Oh, how I admire my beautiful and spontaneous galvanic cell,
The electric current that makes me feel so swell.
It is made of both lead and chlorine,
And an inert platinum electrode that gleams,
A rare and precious metal that would make me rich if I decided to sell.
Electrons travel swiftly through the long copper wire,
From anode to cathode, where reactions occur.
Oxidation gives while reduction receives,
A dance of ions I couldn’t believe,
All powered by potentials no voltmeter could obscure.
Then bubbles arise as the reaction begins,
Yellow chlorine gas forms with a dangerous scent within.
A salt bridge of potassium and nitrate
Keeps the charges in state,
And the battery works, what a marvelous win!
~ David
First we learn half reactions,
to do our work with balanced sides.
We get charges to keep moving,
this is the electric cell design.
Electrons travel through a wire,
to go from place to place
Voltage is the push which gets them moving,
until the charges reach the end.
Electrons are taken at the anode,
and gained at the cathode.
A salt bridge lets the ions flow,
This keeps charges right.
The semester is about to end,
Say bye to our chem morning class.
Though there's little time to lament
as we take a test to see if we pass.
~ Tuomas
Electric Chemistry!
It's Chapter 11's time
So don't let electrochemistry fry your brain
When it comes to studying for the last midterm
Don't refrain
Find out which reaction is oxidation, and which is reduction
For the anode on the left, the buildup is positive, being oxidized
For the cathode on the right, the buildup is negative, being reduced
But for both, the salt bridge forms a truce–a double line in shorthand use
In these Galvanic cells, the reaction is spontaneous
So if there were no relationship between delta G and voltage E, it would truly be heinous
So delta G = -nFE and standard state E = (RT/nF)ln(K)
But when calculating n, make sure those subscripts stay
Or some of those important "minus e's” will incorrectly get lost along the way
Next time you think of a cell or a battery, you can flip that voltage E
But never multiply it because this isn't a change in entropy or enthalpy
And if you're ever stuck in the past, electrochemistry could send you on your way!
Knowing your chemistry always pays
~ Melanie
We learn about the galvanic cell,
Different electrodes, each with a tell.
Anodes and cathodes, tell us the volts,
We measure how, the electron bolts.
A volt is negative work over charge,
We hope that the work that we get, is large.
Batteries serve as the source of a current,
Cells making energy, the pattern recurrent.
Electrolysis places a thin coating of metal,
Like bees pollen on a flower petal.
Dr. Feldwinn told us about fuel cells forming water,
You might think, that a genius taught her.
There is a maximum work a cell can give,
It’s unfortunate, but we can forgive.
Negative w equals qE(max),
No current flowing, this is the tax.
Dry cell battery contains a moist paste,
This is why, we try not to waste.
Corrosion involves the oxidation of metal,
Aluminum, chromium make sure the corrosion doesn’t settle.
This is what we learned in chapter 11,
Electrochemistry and cell potential, 24/7.
~ Ella
Electrons Wander,
Salt Bridge helps voltage through
Anode, Cathode dreams.
~ Andrew
Galvanic Cell Poem
The anode yields its power to the stream,
As oxidation starts the electric dream.
Electrons leave the anode, swift and bold,
Then leaves the ions, lost in the flow.
They reach the cathode on the other side,
Where ions in the liquid wait to ride.
Reduction takes the charge and pulls it near,
As chemical potential becomes clear.
Look up the table for both reactions,
Find the reverse of the oxidation.
To find the voltage, sum the pairs you find,
But flip the sign with oxidation in mind
~ Junxi
The anode said, “This is not fair,
I lose electrons everywhere!”
The cathode laughed, “Well that’s my gain,
They travel to my side again.”
The wire helps them move along,
The salt bridge keeps the charge from wrong.
One side gives, one side gets the show,
And that’s how galvanic currents flow.
~ Breeze
There once was a chemist named Gibbs
Who studied how nature forbids
A reaction to go
Unless ΔG shows
That energy drops, not just fibs.
That measure called entropy, S,
Tracks disorder nothing less.
If particles spread wide
Or change phase in stride,
Then ΔS is positive, yes.
Enthalpy, written ΔH,
Is heat gained or lost in the mesh.
If heat’s given out,
It helps things about
Exothermic systems feel fresh.
He wrote ΔG = ΔH − TΔS,
A formula chemists still bless.
If ΔG’s below zero,
It runs like a hero
If positive? It won’t progress.
~ Alyna
Free energy tells us if a reaction will go,
Spontaneous changes happen, now you know!
Entropy’s a measure of how things can spread,
More ways to arrange means energy’s ahead.
Solids melt, liquids boil, gases fly
Positional probability raises so high.
Dissolve a solid, watch it roam,
Entropy grows as it leaves its home.
Bigger molecules move around and spin,
Higher temperatures let more energy in.
Volume goes up, entropy climbs too,
Higher pressure? It drops, that’s nature’s rule!
Phase changes balance at equilibrium’s gate,
Change in entropy=q/T keeps the math straight.
From melting to boiling, step by step,
Track the changes so your math is strong.
Isothermal expansion is work-free fun,
Remove the weight and zero work’s done.
No matter the process, the rule is the same:
For spontaneous processes, total entropy grows
In nature’s game!
~ Taylor
Our chapter begins learning the first of three laws,
In thermodynamics, we learn without pause.
When energy is used, the amount is unchanged,
But the energy is less useful in the new form we obtain.
Entropy to all spontaneous processes is key,
And it depends on positional probability.
An isothermal process serves to show,
The temperature of a system and surrounding doesn’t flow.
Free expansion occurs without external work and no heat exchanged,
Meaning the temperature of an ideal gas remains unchanged.
As the chapter continues, there's free energy,
It goes hand in hand with delta H and delta S, you’ll see.
At constant temperature and pressure, fundamentally,
A reaction system will proceed spontaneously in the direction that lowers its energy.
~ Saf
Chapters 5 through 9 went by so fast
Try to get out of bed, It's 8am, time for class.
And we finally reached chapter 10
It’s giving more physics then it is chem.
First, we start of with entropy,
Which is represented by the letter S.
This is how energy and matter is distributed
How does it change, were getting there, dont stress
Entropy increases from solid, to liquid, to gas
The same for solids dissolved in liquids, even those in glass
Larger volumes, temperatures, and molecules also make entropy go up
Increasing pressure is the only thing that makes entropy decrease,
Like my dude pressure, what's up?!
For an isothermal expansion of an ideal gas ΔE=0
Which makes work and heat the equation heroes
Entropy of the universe is entropy of systems and surroundings
An increase of these causes spontaneous changes, how astounding!
Finally, we reach G, free energy as it is known
When change in G is zero, the system is at equilibrium, no direction dominates alone
A positive change in G means the forwards reaction is spontaneous,
A negative means the reverse is spontaneous, oh yes!
~ Campbell
Spontaneous Energy
Flip, Flop goes the change in entropy,
From one side of the reaction to the other,
Nature chooses the most spontaneous path,
From a solid to a liquid,
From a liquid to a gas,
The heat and work can help determine that,
Reverse or forward,
Expanding or contracting,
From a little to a lot of free energy,
The total entropy can be found,
Regardless if it is a low temperature,
Or a high temperature,
A positive or negative change,
Spontaneous energy is there always.
~ Melany
While ice will melt, a gas will arise,
Making entropy increase and order die.
A miraculous event is entropy,
An amazing phase change for us all to see.
As explained by the second law,
It's a spontaneous event without a flaw.
The universe is keeping score,
Entropy increases more and more.
But free energy also plays a role,
Delta G decides which way it will go.
If negative, forward we will see,
If positive, it will not be.
At equilibrium things stay the same,
Forward and reverse both in the game.
No net change, just balance there,
Reactions moving everywhere.
Temperature can change the way,
Heat can make it go or stay.
Sometimes it shifts, others times it won’t
Depending on delta H and S, it might or won’t.
~ Sofia
The universe is drifting toward a state of grand decay,
Where order turns to chaos in a silent, slow display.
It’s Entropy, the measure of the madness in the spread,
A dance of many microstates where energy is led.
In Isothermal pathways, where the heat and work align,
The temperature stays steady while the particles entwine.
From liquid turns to vapor, or the melting of the ice,
The Δ S of physical change pays the cosmic price.
The Second Law is absolute: the total must increase,
For every fleeting process, the disorder will not cease.
But Gibbs stepped in to solve the riddle, looking for the key,
To find the driving pressure in his Free Energy.
If Δ G is negative, the reaction finds its way,
A spontaneous transition in the light of common day.
We reach for Absolute Zero, where the Third Law finds its rest,
And use the paths of Hess’s Law to put the heat to test.
Finally, the shouting dies, the forward meets the back,
No longer gaining ground along the thermodynamic track.
The system finds its balance, where the forces all agree,
At the quiet, still perfection of Equilibrium.
~ Diya
I increase from state to state,
Solid, liquid to gas, I inflate.
And when things dissolve,
Or when pressure’s small,
Who am I? Can you guess before it’s too late?
I am a measure of probability,
A choreography of molecules no eye can see.
Oh, wait don’t forget,
Energy levels, you bet!
Who am I? Still a mystery, I see.
To find me involves many steps,
I’ll give you a hint, so you’re not inept.
n delta H over T,
When there’s a phase change to see.
Did you find me? Come on, don’t deflect.
Fine! My code name is the letter S,
Add on a Joules per Kelvin to pass the test
With Boltzmann and microstates,
Better yet, q/T is great.
Who am I? Can you really not guess?
It’s got to be obvious now,
Let’s all make Dr. Feldwinn proud!
Entropy is my name,
Thanks for playing this game.
I’m not gone, you’ll def see me around!
~ Moksha
Spontaneous doesn’t mean fast in pace,
It means the process is thermodynamically in place.
The Second Law makes it clear to see:
The universe gains entropy.
Energy spreads, particles roam,
Gases expand, crystals lose home.
ΔS measures disorder’s rise,
Microstates growing before our eyes.
But heat exchange must join the play-
ΔH shows bonds that form or fray.
Some break apart and absorb the heat,
Some form again and make it complete.
Temperature tips the balance key,
Weighting entropy’s authority.
ΔG = ΔH − TΔS,
The final test of “will it progress?”
If ΔG is negative, it will proceed,
At constant pressure and temperature agreed.
If positive, it will not go-
Not without energy’s extra flow.
Nature doesn’t rush or plea,
It follows lowered free energy.
~ Katharina
Chemistry is hard, especially when learning about entropy
But I can help, here are some keys
Entropy likes when numbers get high, the larger the temperature, the larger this guy
But you thought it was just temperature here, no it is also volume and pressure
Well how can you calculate, well now this is tricky
Make sure to account for phase changes or things might get sticky
Now this is not all thats in this chapter
We also need to think about free energy, its pretty straightforward
As long as you keep your units straight, there is no need to worry
So get out your pencils, chemistry is waiting!
~ Marlee
Energy can change in ways we do not see,
As heat is shared or held from what we start.
The system shifts when things are forced to be,
When space grows wide or walls are pushed apart.
Work happens when a push makes something move,
When pressure changes how much space we have.
The way it happens changes what we do,
Not just the end result we have.
Two states can match but not be solved the same,
Because the change did not occur one way.
A push at once or none, proclaim
A change of how much work is used to pay.
So even if the start and end agree,
The path matters more than the just end we see.
~ Lera
Professor Feldwin, what shall this unit be?
Simply speaking, this chapter is about energy!
Enthalpy is just the total heat,
So, ΔH equals ΔE plus ΔPV
Now that’s pretty neat!
But what path shall we take?
Identify a constant V or constant P
And the first steps we shall make!
Hess lays it out simply, I can’t lie
So don’t fret about calculating ΔH
Just remember to switch the sign and multiply!
Whether in a cup of joe or a bomb
Calorimetry has a constant
So grab your cat equation and stay calm
~ Ryan
8 in the morning, and we start with chem
Students dozing off, can you blame them?
hear the word coffee? -brains wake softly,
But don't be fooled!
its coffee cup calorimeter calling,
At constant pressure, heat we capture,
Be sure to know the quantities of measures,
Before we find what to calculate,
We need to learn the purpose.
Styrofoam cups used to insulate,
Reaction in water you regulate,
Measure heat, isn’t it neat?
Know three different types
We can find c
or even enthalpy,
Depending on the question,
Fusion/reaction, pick your solution!
Heat released from the reaction,
Use q=mCΔT!
Knowing how to solve - brings satisfaction
Do some practice, confidence grows
Midterm in a few days? You already know!
~ Jessie
At 8 a.m. I barely function,
Low internal energy production.
But the First Law says it’s conserved
Energy shifts, it’s not disturbed.
ΔE equals q plus w,
Heat and work both push it through.
If heat flows in, endothermic,
Positive ΔH
If heat flows out, exothermic,
Negative ΔH
At constant pressure we track ΔH,
Enthalpy tells what the reaction gives.
An isolated system stays the same,
Total energy plays no games.
Even if I’m half asleep,
Thermochemistry still balances the heat.
~ Sarah
The movement of energy never fades,
Throughout work, heat is conveyed.
ΔE counts what the systems gain,
When energy rushes in or drains.
Under constant pressure, ΔH speaks,
The heat we release or the heat we seek.
An exothermic reaction warms a room,
It is endothermic that steals the heat bloom.
The volume shifts, work is done,
Push the air or fight with the sun.
Throughout it all, one rule holds true,
Energy is conserved, it just flows through.
~ Esmeralda
Energy moves but stays the same
Changing forms is the name of the game
Heat can flow either in or out
That's what enthalpy is all about
Enthalpy measures heat we see
At constant pressure, we can all agree
If delta H is less than zero heat flows out
But if it is larger than 0 heat is absorbed and cannot float about.
Endothermic takes in heat everyday
But exothermic sends warmth away
Energy shifts everyday
In reactions that are on display
Energy changes all the time
In ways that aren't hard to find
Enthalpy helps explain
How heat is lost or how it is gained.
~ Alexandra
There once was a chemist named Tess,
Who struggled with the heat in a mess.
But Hess had a rule,
Exceptionless, cool:
“Add steps and the totals you’ll guess.”
No matter the pathway you take,
No shortcut or long step you make,
The enthalpy change will not rearrange,
It's the phase that decides what’s at stake.
If reactions are flipped upside down,
Change the sign and don’t frown.
If reactions are multiplied through,
Multiply H too,
Let coefficients lie safe and sound.
Add equations line by line,
Cancel species that hold the same design.
Intermediates fade,
A neat sum is made,
When products and reactants align
From bonds being broken apart,
To new ones that form and restart,
The heat that you track
Is the algebraic stack
Of each reaction's thermal part.
~ Mia
At eight a.m. the board fills fast,
With acids strong and bases past.
Some dissociate all the way,
Some pause where Ka says they may.
Add stress and watch equilibrium shift,
Le Châtelier gives systems a lift.
Buffers stand, the pH stays true,
Holding balance like they’re trained to do.
In every reaction, push and pull,
Nothing stays one-sided or dull.
Even half awake, I finally see
Chemistry loves equilibrium.
~ Piper
A weak acid and its conjugate base,
A pair who cannot be replaced.
In solution together
There isn’t a buffer who’s better
But here comes along OH!
OH and weak acid just happen to meet
A reaction could not be so complete.
But weak acid is so plentiful
And conjugate base so wonderful
Just how could weak acid leave?
Conjugate base, alike in molarity
Ensures a lack of disparity.
Together they resist,
A pH change almost amidst
The pH and pKa in close similarity
~ Gavin
When I was learning buffers
Oh how I suffered
But there’s no time to lament
Problems as hard as cement
Because I know Chem1C will make things tougher
~ Jason
We fill the burette with HCl,
When we know the weak base will rebel.
Not even adding the acid slow,
And yet the pH never gets low.
It’s like it’s under a spell.
~ Marigold
A Buffer keeps the pH in line
Acids and bases are divine
When the two are the same
pKa is the game
And balance is just fine
~ Teddy
Better Together
A weak acid, its conjugate base,
Or, likewise, the reverse
They function all the same.
Together they keep pH in its place,
Or rather I should say, [H+] and [OH-].
Perfectly balanced, there's nothing much stronger,
Than a buffer so equal in volume,
So equimolar.
pH is pKa, that's the way to tell,
What solution you want,
To keep everything going well.
From shampoos and medicine,
To even your own blood.
Life as we know it would not exist,
If not for a buffer, doing its job.
So, If you’re looking for something to save the day,
To hold the pH, to keep things the same.
Don’t fret long.
Don’t run away.
A buffer, A buffer,
A buffer is on its way.
~ Claire
Shout out Bronstead and Lowrey, with out you this never woulda been possible
Your strong acids dissociate so fast they're Unstoppable!
But what happens when they're introduced to a strong base through titration?
The base gets added a drop by drop like menstruation
Then once the equivalence point is reached we pause
The pH is guaranteed to be seven, those are the laws
But not all reactions behave so similarly
Weak acids differ particularly
Take hydrofluoric acid for example
You’d expect the pH to change when the hydrogen added is ample
But this doesn't have to be the case
We can add fluorine, the conjugate base
And so a buffer solution is produced
The H+ created more weak acid, I’ve deduced
So our pH stayed level all thanks to Flourine
Now its time to eat a Professor Feldwinn Tangerine
~ Gavin
Behold chapter seven
A tale to tell
Notes to spin
Into a poem (hopefully) well
Acids give protons to the solution
Bases on contrary take
The terms weak and strong do not warn
Of danger, but tell how much it dissociates
Weak acids and bases partially dissociate
For which Ka and Kb denote extent
Strong acids and bases completely dissociate
With none of their original selves present
pH gives information on proton concentration
For quantifying the acidity of various solutions
Through equation -log(H+;concentration)
One arrives at a mathematical conclusion
Much I could elaborate
And dig into the material deep
But lacking time I find my fate
Is to lay down this work and sleep
~ Ellie
Deep within the molecules of life
Acids and bases in constant strife
A give and take of sought after protons
Acid and bases are chemical icons
To measure their acidity we use pH
Just take the -log with a 10 for the base
A sevens in the middle that is known as neutral
Trying to take a proton from one of these is futile
When the pH is lower than seven it’ll cause a sour taste
Dunk the litmus paper you’ll see the blue erase
Acids turn the paper red while bases keep it blue
All this stuff is measurable based on the papers hugh
When the acids are strong that go through full dissociation
However if they’re weak they’ll be less summation
~ Alex
An acid gives its H+ away,
A base reaches out to stay,
Two become one in shifting roles,
Conjugate partners, trading souls,
Following the Bronsted-Lowry way.
Some break apart, strong and clear,
Some hold back, balance near,
pH tells where waters lean,
Seven’s calm, a quiet scene,
H+ and OH- appear.
~ Aria
It’s 8 a.m., the lights beam loud,
slides shine bright above the crowd.
Dr. Feldwinn speaks with no delay,
Chemistry never waits, wake up, okay?
A Bronsted–Lowry acid gives,
a proton is lost, and a base then lives.
H+ moves fast from bond to bond,
breaking ties, forming one's beyond.
HA dissolves, and its proton is freed,
A- remains, it’s conjugate indeed.
pH drops low when H+ is high,
H+ is fundamental, it’s the reason why.
~ Audrey
In water a strong acid dissociates completely
A weak acid won't dissociate quite as neatly
The concept of strong and weak bases are the same
Weak acids and bases have K values to claim
In the test sheet the values you will find discreetly
~ Andrew
Acids form positive H+, it is kind, it donates
Bases form negative OH-, its greedy, it takes
Strong acids & bases like HCl and NaOH fully dissociate
The stronger it is the weaker it conjugates
Hydrogen and hydroxide always relate
An acidic pH of 2, lemons are great
to the left of the scale it resonates
A basic pH of 12, ammonia will make you feel faint
to the right of the scale its waits
A neutral pH of 7, water is calm and it hydrates
In the middle it mediates
Split a salty compound to identify its traits
When the product is strong a neutral ion it formulates
DI water is neutral it states
rain of an unpolluted area, a basic pH it creates
In industrial areas acid rain it generates
~ Summer
An acid donates a proton, H+ in solution,
Forming its conjugate base by dissociation.
A base accepts protons, reversing the role,
Linked pairs defined by equilibrium control.
pH quantifies hydrogen ion activity,
pOH tracks hydroxide concentration objectively.
Their logarithmic sum, fourteen at standard state,
Defines aqueous systems at equilibrium fate.
Strong acids ionize with complete extent,
While weak acids establish equilibrium, partially spent.
Concentration governs magnitude, not just identity,
In the quantitative language of acid–base chemistry.
~ Elizabeth
Dissociation constant is their weapon
For a pH high or low, starting at seven
A proton to accept or throw
Only they’d know
Acids and bases is the lesson!
~ Kaylee
Acids,
Aren’t so placid
They relish in conjugation
With bases, focused on reorganization
Acids and bases
Focused on homeostasis
Their active protons
Ready to move and hop on
Acids and bases reach elysium
Finally, being in a state of equilibrium
~ Gabi
Acids and Bases
When you're trying to feel more positive, and all you need is that H+.
An acid will always be so kind, and donate it without a fuss.
Bases are the opposite, to acids they are quite strange.
A base will accept your H+, and its sign value will have a +1 change.
Acids have a low ph number, but trust me, they are not flaccid
In Breaking Bad we see the true power of Hydrofluoric acid.
Bases again differ, they don’t burn things at the touch.
They’re ph is higher, and slippery and soapy, they are too much.
They seem quite different, but truly they are siblings not so different from each other.
Using conversions and icetables with one value, you can find that of its brother.
They’re ph and poh will always add to fourteen.
1.0e-14 is where the Ka and Kb product convenes.
In truth, acids and bases compliment each other quite well.
In titrations and acid base reactions, they work together so swell. In Equilibrium reactions, they both play their role.
Just make sure you don’t scoop any of them up, and eat them from your bowl.
~ August
An acid kindly donates a proton to an accepting base in need
In an equation with all weaks, the reaction will proceed
But with a strong acid and strong base staring in your face,
All that’s left is simply H+ and OH-
A pH below 7 is in the acidic range
While above that would be basic, though the equation stays the same
pH equals negative log of H+ concentration
Now we know what’s for cleaning and what's for food disintegration
~ Ava
Low pH means acidic
Now we're getting scientific
If we add more H plus
That causes lower pH for us
Warning strong acids on your skin can be horrific
~ Nina
It amazes me how Ka, just a number so small,
Can tell how many ions choose to leave it all.
They step into water like people into a crowd,
Some shy and some bold, never speaking aloud.
With simple math, we count their choices, reveal all their fates
~ Junbo
“Between H+ and OH”
On a scale from zero to fourteen wide,
Lies a place where acid and bases reside,
The scale chemists trust to clearly tell,
The pH scale is where these strengths dwell.
When H+ ions overpower the base,
The number falls and its an acidic place
Sour solutions fierce and strong,
Where hydrogen ions gather along.
But when OH begins to grow,
The pH rises and the solution starts to flow
Seven stands neutral, all is fair,
Pretty much pure water balanced with care.
With H+ and OH- side by side, neither is able to win the tide.
~ Regan
Acids donate protons with ease,
Bases accept them readily.
Defined by Bronsted-Lowry’s view,
Conjugate pairs form something new.
Strong acids spilt without delay,
Weak ones only partly give way.
Ka and Kb reveal their strength,
Measured by reaction length.
As H+ rises, pH falls,
pOH climbs when OH- calls.
Salts dissolve and shift the scale,
Acidic or basic, trends prevail.
From gases released into the air,
Acid rain forms, chemistry’s there.
~ Ashton
When acids and bases reach equilibrium,
The forward and reverse flow find their rhythm.
Le Châtelier will show
Which way the system will go,
Predicting the shift with minimal delirium.
Strong acids ionize with no hesitation,
Weak ones show only partial dissociation.
The Ka will tell
If they ionize well,
And guide you to the right calculation.
A base can grab a proton with pride,
Forming its conjugate on the side.
pH above seven?
It’s basic, not heaven.
Check concentration, don’t let it slide.
If Kb is tiny, the base is mild,
Strong ones react like a wild child.
Percent ionization low?
Use the x to show
Approximation keeps the math reconciled.
Remember to log when you’re finding the pH,
Mistakes are common, but they’re not your last test.
Double-check your math,
Follow each path,
Soon equilibrium problems will feel like a fresh breath.
~ Ashley
Tanka style poem (5-7-5-7-7)
Products, reactants
Shifts to the right and shifts, left
Le chateliers (le-cha-te-li-ers)
Adding and subtracting heat
the system fights disturbance
~ Aika
The forward reaction runs fast
The reverse matches it refusing to come in last
In dynamic equilibrium
No reaction takes the fun
As they combine to produce a blast
~ Oliver
Equilibrium, equilibrium,
Seems static in the system,
Yet proceeds forward and backward,
Simultaneously, combating against changes.
Products over reactants’ base,
With coefficients raised.
That’s K, the equilibrium constant,
Never change with concentration or pressure.
When the coefficient multiplies,
The change to K applies:
The factor is the exponent.
That’s the new constant.
When the left and right swap,
The constant will flip;
When two reactions add,
Constant will be multiplied.
Want some ice in soda drinks?
Equilibrium says yes!
ICE table is important in calculation,
It tells how the equilibrium changes.
Initial starts the first,
Followed by the change in nx,
Involving the coefficients, equating with constant,
We can find many ways to success.
‘Guess and check’ is useful,
But try simplify first.
Once get the result,
Bring it back to recheck.
Concentration is found,
Everything is done.
Whenever the things change,
We can solve it out.
~ Ziang
Dear Equilibrium,
You have this desire to be seen as dynamic
Others will claim that you already have it
You’ll find the truth in something pragmatic
Reactions will meet, it’s all just a havoc
Pushing and more pushing has led to a habit
Reverse and forward they move how nomadic
Little do you know they can ease all your panic
They continue to argue, but it’s nothing illicit
The solution that awaits will end all this manic
Their problem is solved with one key mechanic
Two sides, one fate, both refuse to just quit
Come together over time, their movement now civic
Don’t you see that their rates are simply organic
Those rates must be equal, two sides, one spirit
Balance has been made it almost feels mythic
Your two sides have done what others see cosmic
Now you understand that you’ve always had it
Equilibrium you are nothing short of dynamic
SoundCloud
~ Sydney
Get the day started with Feldwinn's lecture
A fervent tale of equilibrium
a reversible reaction structure
where forward and backward are in rhythm
the rates are the same, and concentration
stays constant with gas and aqueous state
though particles shift in silent motion
the balance remains, unchanging fate
exponents come from the coefficients
products are favored the larger K is
equilibrium ain't equivalence
temp shifts right and left so beware on quiz
Le Chatelier states when stress is applied,
The system acts to offset the tide.

It can run forward and backward
like a pendulum that swings.
remember it is dynamic.
like a hummingbird's wings
Q is its quotient and K is its constant
you need it to understand the theory of Bronsted
while it is best to make an assumption, if you take it one step at a time
The fundamentals of equilibrium will make Chem 1B a piece of pie.
~ Maisy
There once was an ICE table so neat,
With I, C, and E in a rowed little sheet.
You start with what’s there,
Then change with some x flair,
And end praying algebra admits defeat.
~ Julie
Solve for equilibrium and find k or q
You may have to raise the concentration to the power of one or two
The rate of the forward is equal to the rate of the reverse
This is what equilibrium is for all chemistry in the universe
~ Maya
Equilibrium, forward, reverse
No reaction I can see, so perverse!
Reactions still go
Even though, you know!
They shift back and forth, just to say hello
