What happens when (write balanced chemical equations):
Ammonia is passed through hydrochloric acid.

Explanation

To solve the question of what happens when ammonia (NH₃) is passed through hydrochloric acid (HCl), we need to write the balanced chemical equation for the reaction. Here’s the step-by-step solution:

### Step 1: Identify the Reactants
The reactants in this reaction are ammonia (NH₃) and hydrochloric acid (HCl).

### Step 2: Understand the Reaction
Ammonia is a weak base and hydrochloric acid is a strong acid. When they react, ammonia accepts a proton (H⁺) from hydrochloric acid, resulting in the formation of ammonium chloride (NH₄Cl), which is a salt.
