Answer:

A gas evolution reaction is a chemical process that produces a gas, such as oxygen or carbon dioxide.

Explanation:

key points: Acids react with carbonates to produce a salt, carbon dioxide, and water.

Acids react with carbonates to produce a salt, carbon dioxide, and water.Limewater can be used to detect the presence of carbon dioxide evolved in a reaction.
