Correct Answer

D

Explanation

The correct statement is: "a new substance is formed."

In a chemical change, also known as a chemical reaction, the substances involved undergo a change in their chemical composition, leading to the formation of one or more new substances with different properties. This is a key characteristic that distinguishes chemical changes from physical changes. In physical changes, the substances involved may undergo a change in state (such as melting, freezing, or boiling) or undergo a physical transformation, but their chemical composition remains the same.
