Chemistry 11:  Today we reviewed balancing chemical reactions and did any 15 balancing problems from pg 110 and 111 in Hebdon.  They start easy and transition to very difficult - find the section that best develops your skills.  We also spent time on Lab 4D, which is due on Thursday.  In the second half, we reviewed reaction categories and took notes.  Do pg 118 # 66 any 15 categorizing problems, do not balance these.
