Purpose:
The purpose of this lab exercise is to construct a table of relative strengths of oxidizing and reducing agents. By completing this exercise, you will see how more extensive tables of relative strengths of oxidizing and reducing agents have been developed.
Procedure:
Using the results from the three tables below, prepare a single table of relative strengths of oxidizing and reducing agents.
Table 1. Reactions of metals and nonmetals with solutions of ions.

Cu2 + (aq)

Question:
1. Of the reactions that occurred spontaneously in the individual tables, what types of qualitative changes would you observe that would indicate the reaction is proceeding?
2. For the reactions that occurred spontaneously in the individual tables, balance these reactions assuming they are in an acidic solution.
ANY HELP would be appericate because i dont get wht they are trying to ask and what to do for it.
