    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.
