Today was a busy day with two labs and a discussion of reaction rates and endothermic vs. exothermic reactions. We took a look at just how much water, salt and sugar is in a mole and we also did electrolysis, one of my favorite labs.
Homework for next week is to:
Read pgs. 279 - 300 Don't worry about the #'s and the math.
Investigate electrolysis and create a report telling me:
1. The chemical reactions taking place within the experiment.
2. Why do you think the water changed color?
3. What do you think happened to the paper clip?
4. What do you think happened to the water in the test tube?
5. Why did we need the battery?
6. Why did we need to use salt water?
