![## Galvanic Cell Reaction Description
### Chemical Reaction
The galvanic cell illustrated operates according to the following reaction:
\[ \text{Mg}(s) + \text{PdCl}_2(aq) \rightarrow \text{MgCl}_2(aq) + \text{Pd}(s) \]
### Diagram Explanation
- **Electrodes**:
- **E1** is the electrode in the left beaker labeled as "S1".
- **E2** is the electrode in the right beaker labeled as "S2".
- **Solutions**:
- **S1** contains a solution with a light yellow color.
- **S2** contains a solution with a blue color.
- **Connections**:
- The electrodes are connected by wires through which electrons flow, indicated by the green arrows marked \( e^- \).
- A voltmeter is placed in the circuit to measure the potential difference.
- **Salt Bridge**:
- A salt bridge or porous barrier connects the two solutions S1 and S2 to allow ions to flow and maintain charge balance.
### Questions and Answers
1. **Write a balanced equation for the half-reaction that happens at the cathode of this cell.**
2. **Write a balanced equation for the half-reaction that happens at the anode of this cell.**
3. **Of what substance is \(E_1\) made?**
4. **Of what substance is \(E_2\) made?**
5. **What are the chemical species in solution \(S_1\)?**
6. **What are the chemical species in solution \(S_2\)?**
