Explain the balancing of the given equation by hit and trial method.
`As_2O_3 + SnCl_2 + HCl to SnCl_4+ As+ H_2O`

Explanation

To balance the chemical equation \( \text{As}_2\text{O}_3 + \text{SnCl}_2 + \text{HCl} \rightarrow \text{SnCl}_4 + \text{As} + \text{H}_2\text{O} \) using the hit and trial method, we will follow these steps:

### Step 1: Write Down the Unbalanced Equation
We start with the unbalanced equation:
\[ \text{As}_2\text{O}_3 + \text{SnCl}_2 + \text{HCl} \rightarrow \text{SnCl}_4 + \text{As} + \text{H}_2\text{O} \]

### Step 2: List the Number of Atoms of Each Element
Next, we create a table to count the number of atoms of each element on both sides of the equation.
