1. The student decided to do an experiment with his leftover copper(II) sulfate (CuSO4) solution. He divided the solution up into two beakers. He dropped an iron nail (Fe(s)) into one beaker. He dropped a silver rod (Ag(s)) into the other. Write the chemical equation of any reactions he saw. Explain his results.

2.An electrochemical cell has the following standard cell notation:

AI(s) | AI3+(aq) || Mg2+(aq) | Mg(s)

Write the balanced oxidation and reduction half-reactions, labeling the oxidation reaction and reduction reaction.

What is the standard potential for the cell?

Is this a galvanic cell or an electrolytic cell? Explain your answer.

Write the balanced redox equation for the cell using the oxidation and reduction half-reactions.
