### Multiple Choice Question 6

**What is being oxidized and reduced in this reaction?**

Reaction:
\[ \text{Fe}_{(s)} + \text{CuSO}_4{(aq)} \rightarrow \text{FeSO}_4{(aq)} + \text{Cu}_{(s)} \]

Options:
A. Fe is oxidized and Cu is reduced.
B. Cu is oxidized and Fe is reduced.
C. The oxidation states of both Fe and Cu do not change.
D. Oxygen is oxidized and sulfur is reduced.

### Explanation:
To determine what is being oxidized and what is being reduced in the reaction, identify the changes in the oxidation states of the elements involved:

1. **Oxidation**: Refers to the loss of electrons.
2. **Reduction**: Refers to the gain of electrons.

In the given reaction:
- Fe (iron) starts with an oxidation state of 0 (elemental form) and ends with an oxidation state of +2 (in FeSO₄).
- Cu (copper) starts with an oxidation state of +2 (in CuSO₄) and ends with an oxidation state of 0 (elemental form).

Thus, Fe loses electrons (is oxidized) and Cu gains electrons (is reduced).

**Correct Answer:**
A. Fe is oxidized and Cu is reduced.
