Chemistry 11:  We started with some review of percent composition and finding empirical formula, looking at SiO2 (quartz crystals).  pg 90 and 92 in Hebdon have the questions we did back in March on these skills, try a few for review.  A few examples on the board, and looking at the molecular model kit showed everyone about how to name and draw structures of cyclic hydrocarbons.  Read pg 222 -225 and do Unit 10 # 15 and 16, drawing every structure.   Finish Lab 6C, which is due Monday (all questions, follow-up questions, and a conclusion).  For those who had time, we started a year end review WS on the Moles Unit.  In the second half, we took notes on the names and structures of Haloalkanes, read 10.3, and did Unit 10 # 17-20.  All the textbook work is due Friday.

Chemistry 12:   Unit 5 # 47,48, 41-43.  Labs 21C and 21D are due Tuesday.  Test on Electro-chem on Thursday am.
