On tuesday's class we went over questions 2-11 on page 21

We also learned how to determine the following:
-which element is being oxidized or reduced
-an element is being oxidized if it has a loss in electrons. The charge becomes more positive
-an element is being reduced if it has a gain in electrons. The charge becomes more negative
-which substances are the oxidizing or reducing agent

For hand in we had to do questions 12-17 on page 21
