Balance the chemical equations :
`Cl_2+SO_2 + H_2O to H_2SO_4 +HCl`

Explanation

To balance the chemical equation \( \text{Cl}_2 + \text{SO}_2 + \text{H}_2\text{O} \rightarrow \text{H}_2\text{SO}_4 + \text{HCl} \), we will follow these steps:

### Step 1: Write down the unbalanced equation
The unbalanced equation is:
\[ \text{Cl}_2 + \text{SO}_2 + \text{H}_2\text{O} \rightarrow \text{H}_2\text{SO}_4 + \text{HCl} \]
