Balance the following equations
`As_2O_3 + SnCl_2 + HCl to SnCl_4 + As + H_2O`

Explanation

To balance the chemical equation `As₂O₃ + SnCl₂ + HCl → SnCl₄ + As + H₂O`, we will follow these steps:

### Step 1: Write down the unbalanced equation
The unbalanced equation is:
\[ \text{As}_2\text{O}_3 + \text{SnCl}_2 + \text{HCl} \rightarrow \text{SnCl}_4 + \text{As} + \text{H}_2\text{O} \]

### Step 2: Count the number of atoms of each element on both sides
- **Left-hand side (LHS)**:
