Question

1 Calcium carbonate and hydrochloric acid react
together to form carbon dioxide. Name another
carbonate and another acid that could be used
instead. Write a balanced equation for the reaction
that takes place.

Answer 1

Answer:

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.
