Balance the chemical equations :
`K_2CO_3 + H_2SO_4 to K_2SO_4 +CO_2+H_2O`

Explanation

To balance the chemical equation \( K_2CO_3 + H_2SO_4 \rightarrow K_2SO_4 + CO_2 + H_2O \), we will follow these steps:

### Step 1: Write down the unbalanced equation
The unbalanced equation is:
\[ K_2CO_3 + H_2SO_4 \rightarrow K_2SO_4 + CO_2 + H_2O \]

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