Thank you for this!

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

Resolving the hw problems, the two tests, the midterm and attending review sessions

Mercan Bayazit 4E

This week in discussion section I would guess

Mercan Bayazit 4E

Check for standard conditions such as 25C

Mercan Bayazit 4E

Include H+ but do not include H2O

Mercan Bayazit 4E

Solving all the hw problems and reviewing the lectures is the best way for me

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

Mercan Bayazit 4E

Yes balancing redox reactions will be on the test.

Mercan Bayazit 4E

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

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

Mercan Bayazit 4E

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

Mercan Bayazit 4E

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

Mercan Bayazit 4E

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

Mercan Bayazit 4E

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.

Mercan Bayazit 4E

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.

Mercan Bayazit 4E

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.

Mercan Bayazit 4E

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