Answer

Brief Explanations:

A chemical change results in the formation of new substances. When hydrochloric acid and magnesium react and produce a gas, new chemical substances are formed. In a physical change, no new substances are created, only the physical state or appearance changes. Since a gas (a new substance) is produced here, it is a chemical change.
