Re: Final
Sig figs are probably important to keep in mind, but I would pay even more attention to the units and conversions to be on the safe side

Check for standard conditions such as 25C

Re: How are you guys going to study for Test 2?
Solving all the hw problems and reviewing the lectures is the best way for me

Re: Order to balance
First you need to balance elements, then O and H and then finally the electrons.

Re: kJ vs J
You can use whichever as long as you make sure your conversion is correct (1kJ = 1000J).

Re: Calorimeter
We will most likely need to know how to calculate and solve examples with the calorimeter.

Re: Units for pressure
Yes, I think we generally use atm for pressure, even though the difference is small.

Re: Water in ICE tables
Because unlike the other molecules in the reactions we see, water is a pure liquid and we therefore omit it in the ICE tables.

Re: ICE Table Calculations
Yes, I think we may need to solve problems with ICE tables that have more than 3 species.

Re: Q and K
K is the equilibrium constant so the reaction needs to be at equilibrium in order for us to calculate K. Q, on the other hand, can be calculated at any time during the reaction and there does not need to be an equilibrium.

Re: ICE Tables
Because the reactants are used up to form the products, I would assume that the reactants will always show a negative change and so have -x on the table and the products will be increasing and have +x as the change.

Re: equations
You need to write out the chemical reaction, sometimes they are given to you in the question, other times the wording of the question gives it away, like A and
B react to make C and D or something similar to that.

Re: Calculating Q
When calculating both Q and K we put the products over the reactants, so it is the same as K.
