A salt X is formed and a gas is evolved when ethanoic acid reacts with sodium hydrogen carbonate. Name the salt X and the gas evolved. Describe an activity and draw the diagram of the apparatus to prove that the evolved gas is the one which you have named. Also, write the chemical equation of the reaction involved.

Explanation

### Step-by-Step Solution:

1. **Identify the Reactants**: The reactants in the reaction are ethanoic acid (CH₃COOH) and sodium hydrogen carbonate (NaHCO₃).

2. **Determine the Products**: When ethanoic acid reacts with sodium hydrogen carbonate, a salt, water, and carbon dioxide gas are produced. The salt formed in this reaction is sodium ethanoate (CH₃COONa).

3. **Write the Chemical Equation**: The balanced chemical equation for the reaction is:
\[
