Fusion is a type of chemical reaction true or false

True.

Explanation:

Hello,

Fusion, more specifically, nuclear fusion is a nuclear process, in which energy is produced in the form of heat by smashing together light atoms. It is the process by which the sun and other stars generate light and heat as well.

On the attached document, you will find an example wherein deuterium and tritium combine to yield energy, helium and a neutron, validating that the initial composition is quite different than the final one, thus, fusion is actually a type of nuclear chemical reaction.

Best regards.
