Ammonia, calcium chloride and water are obtained by heating a mixture of ammonium chloride and calcium hydroxide.
Write a balanced equation of the reaction.

Explanation

To write a balanced equation for the reaction of ammonium chloride (NH4Cl) and calcium hydroxide (Ca(OH)2) when heated, we can follow these steps:

### Step 1: Write the unbalanced equation
The first step is to write the reactants and products based on the information given. The reaction involves ammonium chloride and calcium hydroxide, which produces ammonia (NH3), calcium chloride (CaCl2), and water (H2O).

**Unbalanced equation:**
\[ \text{NH}_4\text{Cl} + \text{Ca(OH)}_2 \rightarrow \text{NH}_3 + \text{CaCl}_2 + \text{H}_2\text{O} \]
