Justify that the reaction is a redox reaction.
`" "2Cu_(2)O(s)+Cu_(2)S(s) rarr 6Cu(s)+SO_(2)(g)`

Explanation

To justify that the reaction \( 2Cu_{2}O(s) + Cu_{2}S(s) \rightarrow 6Cu(s) + SO_{2}(g) \) is a redox reaction, we need to analyze the changes in oxidation states of the elements involved in the reaction.

### Step-by-Step Solution:

1. **Identify the Reactants and Products**:
- Reactants: \( Cu_{2}O \) and \( Cu_{2}S \)
- Products: \( Cu \) and \( SO_{2} \)
