I was very impressed how quickly you caught on to Stoichiometry (relationships between reactants and products)We will do a lab on Tuesday and see if you can get the right amount of salt from the baking soda.

For Monday: Finsih to 50.  Omit c and d on the following- 33,36,49 and on 42 produce chromium III oxide.

Monday: Finsih equations
