* Decomposition: A single reactant breaks down into two or more products.

* Chemical Reaction: The molecules of the reactant are rearranged, forming new substances with different properties.

In this case, hydrogen peroxide (H₂O₂) decomposes into water (H₂O) and oxygen gas (O₂):

2 H₂O₂ → 2 H₂O + O₂
