Activity+15+-+Day+4+chemical+changes

Here is activiity 15 on chemical changes. It will follow the Menots and Diet Coke demo. I will also have two redox demos set up at the beginning. One with copper wire in silver nitrate and one with copper wire in zinc sulfate. Explanations on types of reactions, especially oxidation/reduction will be given, along with a review of writing and balancing equations. All done in 45 minutes ?????? :)
