Write balanced chemical equations for these equations :
Marble (calcium carbonate) is dissolved in hydrochloric acid to give calcium chloride, water and carbon dioxide.

Explanation

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

### Step 1: Write the unbalanced chemical equation
The first step is to write the unbalanced chemical equation based on the information provided. The reactants are calcium carbonate (CaCO₃) and hydrochloric acid (HCl), and the products are calcium chloride (CaCl₂), water (H₂O), and carbon dioxide (CO₂).

**Unbalanced equation:**
\[ \text{CaCO}_3 + \text{HCl} \rightarrow \text{CaCl}_2 + \text{H}_2\text{O} + \text{CO}_2 \]
