Physical and chemical changes are reversible and nonreversible changes. The release of carbon dioxide gas indicates a chemical change.

The release of carbon dioxide is a chemical change as limestone and hydrochloric acid react with each other chemically and as a result, a new substance was formed.

Therefore, the production of carbon dioxide indicates a chemical change.
