A mixture of `Cu_2O` and `Cu_2S` is heated. Write a balanced chemical equation.

Explanation

To write the balanced chemical equation for the reaction between a mixture of \( \text{Cu}_2\text{O} \) (copper(I) oxide) and \( \text{Cu}_2\text{S} \) (copper(I) sulfide) when heated, we can follow these steps:

### Step 1: Write the unbalanced equation
When \( \text{Cu}_2\text{O} \) and \( \text{Cu}_2\text{S} \) are heated, they react to form copper (Cu) and sulfur dioxide (\( \text{SO}_2 \)). The initial unbalanced equation is:
\[ \text{Cu}_2\text{O} + \text{Cu}_2\text{S} \rightarrow \text{Cu} + \text{SO}_2 \]
