Answer

Brief Explanations:

A chemical change occurs when a new substance is formed. When calcium carbonate reacts with hydrochloric acid, gas (carbon dioxide) is produced, indicating a chemical reaction where calcium carbonate is transformed into different substances like calcium chloride, water, and carbon dioxide. Physical changes do not result in new substances being formed.

Answer:

chemical change because gas formation was observed, which indicated that the calcium carbonate was transformed into a different substance
