3 - Making Carbon Dioxide - IGCSE Chemistry
Calcium Carbonate + Hydrochloric Acid --> Calcium Chloride + Water + Carbon Dioxide. You would see the Calcium Carbonate slowly dissolve and the Carbon Dioxide being made as bubbles. But you would not see the Calcium Chloride or the water being made since there is already water in the flask and the C al cium Chloride will dissolve in it.

Calcium - Wikipedia
Calcium is a chemical element with the syol Ca and atomic nuer 20. As an alkaline earth metal, calcium is a reactive metal that forms a dark oxide-nitride layer when exposed to air. Its physical and chemical properties are most similar to its heavier homologues strontium and barium. It is the fifth most abundant element in Earth''s crust
