Which gas will be produced when heavy water is treated with a mixture of calcuim nitride and magnesium nitride? Give equations.

Explanation

To determine which gas is produced when heavy water (D2O) is treated with a mixture of calcium nitride (Ca3N2) and magnesium nitride (Mg3N2), we can analyze the reactions that occur with each nitride.

### Step-by-Step Solution:

1. **Identify the Reactants:**
- Heavy water (D2O)
- Calcium nitride (Ca3N2)
- Magnesium nitride (Mg3N2)
