Answer:
It is a decomposition reaction.
Explanation:
In a decomposition reaction, a single substance breaks down or breaks down, producing two or more different substances. In other words, decomposition reactions are those that form two or more substances from a compound. In this reaction the atoms that form a compound are separated to give the products according to the formula:
AB → A + B
This type of reactions can occur spontaneously or caused by certain external factors, such as heat.
In this case, you will see that the H₂O molecule decomposes to form two substances: H₂ and O₂. Then you will see that it is a decomposition reaction.
