Give balanced equations for
Reduction of hot copper (II) oxide to copper using ammonia gas.

Explanation

To balance the equation for the reduction of hot copper (II) oxide (CuO) to copper (Cu) using ammonia gas (NH3), we will follow these steps:

### Step 1: Write the unbalanced equation
The unbalanced chemical equation for the reaction is:
\[ \text{CuO} + \text{NH}_3 \rightarrow \text{Cu} + \text{N}_2 + \text{H}_2\text{O} \]

### Step 2: Identify the number of atoms of each element
- On the reactant side:
