Write the cell reaction for the cell
`Sn"|"Sn^(2+)"||"Au^(3+)"|"Au`

Explanation

To write the cell reaction for the electrochemical cell represented as \( \text{Sn} | \text{Sn}^{2+} || \text{Au}^{3+} | \text{Au} \), we need to identify the oxidation and reduction half-reactions occurring at the anode and cathode, respectively.

### Step-by-Step Solution:

1. **Identify the Anode and Cathode**:
- The left side of the cell notation (Sn | Sn²⁺) represents the anode where oxidation occurs.
- The right side of the cell notation (Au³⁺ | Au) represents the cathode where reduction occurs.
