When excess of ammonia and chlorine react, nitrogen and ammonium chloride are formed. Write the balanced equation and find out how manty ammonium chloride molecules are involved in the balanced equation ?

Explanation

To solve the problem, we need to write the balanced chemical equation for the reaction between ammonia (NH₃) and chlorine (Cl₂) that produces nitrogen (N₂) and ammonium chloride (NH₄Cl). We will then determine how many molecules of ammonium chloride are formed in the reaction.

### Step 1: Write the unbalanced equation
The unbalanced equation for the reaction is:
\[ \text{NH}_3 + \text{Cl}_2 \rightarrow \text{N}_2 + \text{NH}_4\text{Cl} \]

### Step 2: Identify the number of each atom
- On the left side (reactants):
