The Exam

We spent most of today going over the exam.  Exam 3 will cover a LOT of the same material, so make sure that you use your performance on Exam 2 to guide you toward the areas you need to study more.  Having graded the exam, I can identify polyatomic ions as the biggest problem most people had.  There's no real trick for polyatomic ions, you just have to memorize them.  As with anything (music, language, sports, etc), the more you practice the more automatic a thing becomes.  When you write out the formula for nitrate 100 times while you're studying, you will tend to remember the formula for nitrate.

We also did a quick heat capacity problem at the end of class, we'll get more into that next week.  Keep an eye on the schedule, Exam 3 is a week from Monday, so it's coming up quickly.  Have a good weekend.
