Answer:
Double decomposition reaction
Explanation:
When hydrochloric acid reacts with any carbonates/hydrogen carbonates the products formed are metal chloride , water and carbon dioxide.Since HCl decomposes salts of weaker acids.
So the equation of the reaction between calcium carbonate and HCl is:
CaCO3+2HCl =CaCl2+H2O+CO2
This reaction is also known as double decomposition reaction.

Answer:
3.14 moles of hydrogen are produced
