Answer: The given statement is true.

Explanation:

A chemical change is a change that causes change in chemical composition of a substance.

This change is due to the exchange of electrons that lead to the formation or breaking of bonds.

For example, sodium atom on donating an electron to chlorine atom forms an ionic bond due to transfer of electron.

This formation of ionic bond leads to the formation of a new compound named as sodium chloride.

Therefore, we can conclude that the statement a chemical change involves the formation or the breaking of bonds, is true.
