Complete and balance the following chemical equations :
`CaCO_(3(s))+ H_(2) O_((l)) + CO_(2(g)) to`

Explanation

To complete and balance the given chemical equation, we will follow these steps:

### Step 1: Write the unbalanced equation
The unbalanced equation is:
\[ \text{CaCO}_3(s) + \text{H}_2\text{O}(l) + \text{CO}_2(g) \rightarrow ? \]

### Step 2: Identify the products
When calcium carbonate (CaCO₃) reacts with water (H₂O) and carbon dioxide (CO₂), it forms calcium hydrogen carbonate (Ca(HCO₃)₂). Thus, the products can be written as:
...
