Answer 2

Answer:

carbon dioxide

Explanation:

When acids react with carbonates, such as calcium carbonate (found in chalk, limestone and marble), a salt, water and carbon dioxide are made. The carbon dioxide causes bubbling during the reaction, which is observed as fizzing. It can be detected by passing the gas through limewater, which will go cloudy.
