Question

What type of reaction is shown in the following chemical equation: 2H2O → 2H2 + O2?

Answer 1

Answer:

Decomposition

Explanation:

A reaction in which one compound breaks up into two or more compounds is called a decomposition reaction.

Answer 2

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.
