I believe Professor Lavelle said we were going to cover only up to second order

Arman M 1A

Anyone have an idea of what kind of questions to expect on the final?

Got some pictures

Does Dr. Lavelle curve the final grades for his class?

Arman M 1A

I believe it is cumulative from what we covered throughout the quarter.

Is there a simple method used to balance redox reactions occurring in a basic solution? By that I mean is there a way of balancing redox reactions in a basic solution by reducing the amount of thought we have to put into such questions?

Arman M 1A

By any chance does anyone know if the solutions for test #2 is going to be released?

Arman M 1A

Also, remember that you add H+ and H2O when the redox reaction occurs in a acidic solution. If it takes place is a basic solution, you use OH- and H2O to balance the redox reaction.

In a cell diagram, when do you include a solid and why do we have to include a solid? Also, Is the solid always going to be Pt(s)?

Arman M 1A

I highly doubt that the second test would be curved :(

Arman M 1A

Can someone give an example of expansion and non-expansion work?

I'm hoping this video answers your question.

Arman M 1A

If delta G is less than zero, this means a reaction is always product-favored
If delta G is greater than zero, this means a reaction is always reactant-favored

Arman M 1A

What is the exact difference between isothermal and free expansion?

Arman M 1A

I don't believe you necessarily need to always convert the pressure to atm because when you solve for Kp, you can use bars as well for the units.

Arman M 1A

If ΔU = 0, does that always mean that the process is isothermal? If so, why?

Arman M 1A

Helium walks into a bar,
The bar tender says "We don't serve noble gasses in here."
Helium doesn't react.

Arman M 1A

Why is energy of an isolated system always constant at equilibrium?

Arman M 1A

What is the difference between enthalpy and entropy?

Arman M 1A

How do you determine if a system is open, closed, or isolated?

Arman M 1A

What is pV=nRT used for?

Arman M 1A

Don't be So Salt - y. I don't know why the Y isn't included at the end lol!

Arman M 1A

Why is getting burned from steam more damaging than getting burned with boiling water of the same temperature?

Arman M 1A

How does change in pressure affect gas-phase equilibria?

Arman M 1A

You can determine whether an acid/base is strong or weak by solving for Ka and Kb. If Ka/Kb is larger than 10^-3, consider it to be strong. If it is less than 10^-3 consider it weak.

Arman M 1A

What is autoprotolysis?

Arman M 1A

How do you differentiate strong acids and bases from weak acids and bases?

Arman M 1A

Water can either be a liquid, solid, or gas. Any substance that has been dissolved in water is said to be in an aqueous state (remember that aqua means water). For water to be in an aqueous state is in itself, a contradiction.

Hi everyone, I recently switched my chemistry series from the 20 series to the 14 series. I took CHEM 20A with Baugh in the fall quarter and decided to take CHEM 14B with Lavelle. What are some main concepts from CHEM 14A that I should know that would help me in CHEM 14B? Anything would help!
