Question

1. Describe how oxidation and reduction affect the oxidation number of an element.

2. Solid copper sulfide and silver nitrate react to form copper (II) nitrate and solid silver sulfide. Write a balanced chemical equation that describes the reaction. Identify the oxidation number of each element in the reaction. (You do not need to include the total contribution of charge.) Is this reaction a redox reaction or a non-redox reaction? Explain your answer.

3. How does ease of oxidation correlate with activity? Do highly active metals tend to donate electrons or accept electrons from other metals?

4. Create an activity series for copper, lead, and zinc. Place the most active metal at the top of the list.
