Chemistry 12:  I did not get to see Unit 2 # 15 & 16, so please have it ready to show me on Thursday.  Today we did Lab 19B Parts I (make a dilution series) and Part II ( measure absorbance to find concentration).  Some groups will do Part II on Thursday.  No Lab homework, but I do want you to finish the WS titled "Review of 2.1 to 2.3" for Thursday.

Chemistry 11: Unit 5 # 6 & 7 (any 10 problems total) and # 8 & 9 (any 12 problems total).  Show math statements for everything and check answers along the way, paying attention to the number of digits in your final answers.  You were also given your myed login and password, and I would like you to be keeping track of your progress in Chemistry 11.
