Balance the following chemical equations and identify the type of chemical reaction.
`H_(2)O_(2) (l) overset(UV)to H_(2)O(l) + O_(2)(g)`

Explanation

To balance the chemical equation and identify the type of reaction, we will follow these steps:

### Step 1: Write the unbalanced equation
The unbalanced chemical equation is:
\[ \text{H}_2\text{O}_2 (l) \overset{UV}{\rightarrow} \text{H}_2\text{O} (l) + \text{O}_2 (g) \]

### Step 2: Count the number of atoms of each element
