Which of the following is NOT true of a chemical change? A. Chemical bonds are broken B. The identity of a substance has changed C. The substance has only changed form or appearance D. It can be identified by the presence of bubbles or rust

Answer 1

C. The substance has only changed form or appearance

This statement is NOT true of a chemical change. A chemical change involves a transformation that alters the identity of a substance, not just its form or appearance. In contrast, a physical change only affects the form or appearance without changing the substance's chemical identity.
