Balance the equations given below :
`K_2Cr_2O_7 + H_2SO_4 +SO_2 to K_2SO_4 + Cr_2(SO_4)_3 + H_2O`

Explanation

To balance the chemical equation \( K_2Cr_2O_7 + H_2SO_4 + SO_2 \rightarrow K_2SO_4 + Cr_2(SO_4)_3 + H_2O \), we will follow these steps:

### Step 1: Write down the unbalanced equation
The unbalanced equation is:
\[ K_2Cr_2O_7 + H_2SO_4 + SO_2 \rightarrow K_2SO_4 + Cr_2(SO_4)_3 + H_2O \]

### Step 2: Count the number of atoms of each element on both sides
