Answer:

D. silver tarnishing as the silver metal reacts with sulfur​

Step-by-step explanation:

A chemical change occurs when the identity of a substance is changed. Silver tarnishing is a chemical change because silver and sulfur react to form a new substance, silver sulfide. In the other examples, the substances have not changed their identity and only physical changes have occurred.
