chemistry equations

[anthony2001]

Hi, i've been studying chemistry and i know we should know the gas equations and stuff, but are there other specific equations that i should memorize as well? Mainly the electrochemistry ones. Thank!

I dont remember having any memorized equations other than the basic pv=nrt calculations on the June test. Lots of stochiometry though.

It doesn't hurt to know Gibbs free energy, delta G = delta H - (T x delta S). There could be a question like: if delta H is positive, and delta S is negative, will the reaction be spontaneous or not? (Remember: if the delta G is negative, the rxn is spontaneous).

You should probably remember q=mC(delta)T or as we used to remember it q=mCAT. You might not use it, but if you don't remember it you will lose out on an easy question.
