Classify what type of reaction occurred for hydrogen peroxide (there are 5 types you learned): a decomposition reaction occurred due to its characteristics. these characteristics are when a chemical change breaks down a compound into one or two simpler compounds, which in this case were water and gas.

A Reaction of decomposition is ocurred to hydrogen peroxide.

Explanation:

Hydrogen peroxide is a molecule that can break down into Hydrogen and Oxygen or decompose very slow under moderate temperature, as you can see in the image below, hydrogen peroxide has a high electronic cloud that makes it a great oxidizer.
