Here's some more practice problems for you to try: one exam from 2010, and another compilation from earlier than that (note: there is an error in Q38, the formula should be C4H8O, not C4H10O.
I recorded myself solving the compilation. The picture is a little fuzzy and the sound not great, but if you get stuck on a particular question and want to know how I got the answer, just skip through the video until you find it. I went through problems at roughly 1/minute. I circled the wrong answer in Q4 AND Q7 (the answers are right in the key); sorry! See how easy it is to make silly mistakes when you're rushing?
Dr Briggs reports that answers to old exams are not posted for any course. I am of course happy to answer any questions you have during the review session, office hours, etc.
