That is all
Haha...yeah well for me PChem I lab and lecture sucked, but I loved PChem II. I just like quantum better than thermo.

I loved PChem. I think having tons of math helped a bunch... complex variable calculus was a particularly helpful course, and I wish I'd had abstract algebra before pchem.
But i'd MUCH rather do pchem than biochem. Any day. Hands down.
<-- PChem and Biochem next semester
to top it off, its been 3 years since multivar.... I love to hate myself...
P. Chem tells you what type of lab alcohol is okay to spike your drinks with. 95% = good, 100% = bad. Since ~97% ethanol/H20 is an azeotrope, you can't distill past that point without spiking it with something nasty (like benzene). This is the most memorable thing I learned in p chem (although to be honest it pops up in orgo as well).

When I took PChem a lot of the chemistry students bombed it simply because they sucked at algebra. The math in PChem is basic, nothing harder than some simple integrals or derivatives. The chem students that sucked at pchem simply couldn't do algebra.
100% ethanol is impossible to achieve (but would in theory be perfectly safe). Also, lab grade ethanol has methanol impurities in it, which forms the azeotrope you referred to. Methanol in small quantities (even < 10mL) will:
A) Make you blind
B) Kill you
Moral of the story: Don't drink anything in lab
(PS: I know it was a joke, but some people might be dumb enough to try.)
