Question
A chemist designs a galvanic cell that uses these two half-reactions:

| half-reaction                                   | standard reduction potential         |
|-------------------------------------------------|-------------------------------------|
| \( \text{Zn}^{2+}(aq) + 2e^- \rightarrow \text{Zn}(s) \)       | \( E^\circ_{\text{red}} = -0.763 \, \text{V} \) |
| \( \text{MnO}_4^-(aq) + 2 \text{H}_2\text{O}(l) + 3e^- \rightarrow \text{MnO}_2(s) + 4 \text{OH}^-(aq) \) | \( E^\circ_{\text{red}} = +0.59 \, \text{V} \) |

Answer the following questions about this cell.

1. Write a balanced equation for the half-reaction that happens at the cathode.

   [Cathode space for answer]

2. Write a balanced equation for the half-reaction that happens at the anode.

   [Anode space for answer]
