Kb is given already, it should be on the constant sheet

Celio_G_Dis2C

Not sure about exception, but one side of the cell diagram must have a conducting metal solid

Celio_G_Dis2C

If you are given two reactants

Q: What did the scientist say when he found 2 isotopes of helium?
A: HeHe

Celio_G_Dis2C

: Anyone know any jokes about sodium?
A: Na

Celio_G_Dis2C

I asked the guy sitting next to me if he had any Sodium Hypobromite…
He said NaBrO

Celio_G_Dis2C

Whats the difference between a Comma and a vertical line?

Celio_G_Dis2C

Is platinum used as the electrode when the redox reaction lacks a solid on either side, oxidation and or reduction?

Celio_G_Dis2C

"Delta G is non-spontaneous when both Delta H and Delta S are positive. Moreover, it can be that both Delta H and Delta S are negative. " is not correct. It MAY become nonspontaneous

Celio_G_Dis2C

When delta H and delta S have differing signs then the reaction is temperature dependent

Celio_G_Dis2C

the reactions occur by themselves therefore they occur spontaneously

Celio_G_Dis2C

I didn't even know he was making one

I'm currently taking in tandem with my 14B and I can safely say you'll de very well in the class if you have Casey because she puts in the effort to help students not only understand the concepts but also be able to interpret and apply it elsewhere. If you took AP Chem in HS it should be a breeze be...

Celio_G_Dis2C

you would add exponentents M and N

Celio_G_Dis2C

How would we integrate it? I thought we only integrate when we want to get from a rate order of 2, for example to rate order 1

Celio_G_Dis2C

So I'm in 14B but this is my first 14 series class (I came from 20A) so I fail to understand how Lavelle's homework system works. How do I know what my homework problems are supposed to be on because he doesn't specify most of the time

Celio_G_Dis2C

It's part of the standard conditions of an ideal gas just as 1 atm is the condition for pressure

Celio_G_Dis2C

K is unit less because all units should cancel each other out

Celio_G_Dis2C

So the syllabus says that a 50% is required o pass the class with at least a C- but at the same time, "there's no curve" is what I've been hearing from most students so if I have a 75% in the class it'll remain the same but if I get a 50% it'll jump up to 70%?

OIL RIG is much better but I learned it as "LEO the lion goes GIR" but both do the job of helping you remember which is which

Celio_G_Dis2C

T will mostly affect free energy only. One might think that it also changes enthalpy because the addition of heat will change the forward/irreversible reactions of an equation but the change is minimal

Celio_G_Dis2C

Doesn't matter as long as it is easy to read (ie Don't have it in joules if you just have it look neater in kj like 10 kJ instead of 10000J) cause the point of science is to be universal and for our data to be easily read and interpreted

Celio_G_Dis2C

Judging from Lavelle's email sent out this weekend, Gibbs Free Energy

Celio_G_Dis2C

that's what causes batteries to die

Celio_G_Dis2C

The adding of these instruments allows for the circuit to continue because there won't be a large accusation of electrons since the purpose of It is to pass ions from one end to another in order to neutralize

Celio_G_Dis2C

Either is fine as long as you're careful as to keeping them constant throughout the calculation because I've noticed that the textbook tends to give enthalpy in terms of kJ and Entropy in J so when you're adding them to get Gibbs Free energy make sure they're the same

Celio_G_Dis2C

I think stability is based on the use of energy. The universe favors disorder as we've learned from entropy therefore the larger the entropy the more negative our Gibbs free energy gets. That's why if our Gibbs free energy is negative it's stable because its spontaneous meaning that the universe pre...

Celio_G_Dis2C

When science becomes ambiguous, I'd stick to what most use. In this case; H+

Celio_G_Dis2C

It's a state function due to its upbringing that stems from the incorporation of two other state functions: Enthalpy and Entropy

Celio_G_Dis2C

Porous disk ~ Salt bridge: both serve the function of transferring ions

Celio_G_Dis2C

When I read the textbook, I get really overwhelmed so I stray away from it :)

Celio_G_Dis2C

Wouldn’t it be easier for a solid to heat up if the surface area is larger? I keep thinking about baking. It’s easier to bake the bread if the mold is less deep and the surface area is increased given the same amount of dough

Celio_G_Dis2C

What’s the difference between them seeing as they’re calculated the same way?
