Write a balanced chemical equation for the reaction between sodium carbonate and hydrochloric acid indicating the physical state of the reactants and the products.

Explanation

To write a balanced chemical equation for the reaction between sodium carbonate and hydrochloric acid, we will follow these steps:

### Step 1: Identify the Reactants
The reactants are sodium carbonate (Na2CO3) and hydrochloric acid (HCl).

### Step 2: Write the Unbalanced Equation
The unbalanced chemical equation can be written as:
\[ \text{Na}_2\text{CO}_3 (s) + \text{HCl} (aq) \rightarrow \text{NaCl} + \text{H}_2\text{O} + \text{CO}_2 (g) \]
