Write the balanced chemical equations for the following reactions :
Sodium carbonate on reaction with hydrochloric acid in equal molar concentrations gives sodium chloride and sodium hydrogencarbonate.

Explanation

To write the balanced chemical equation for the reaction of sodium carbonate with hydrochloric acid, we will follow these steps:

### Step 1: Identify the Reactants
The reactants in this reaction are sodium carbonate and hydrochloric acid.
- Sodium carbonate is represented as \( \text{Na}_2\text{CO}_3 \).
- Hydrochloric acid is represented as \( \text{HCl} \).

### Step 2: Identify the Products
