    formed.
    A Water Correct Answer Incorrect Answer
    B Carbon dioxide Correct Answer Incorrect Answer
    C Salt Correct Answer Incorrect Answer
    D All of the options Correct Answer Incorrect Answer

    Solution

    When an acid reacts with a metal carbonate, salt, water, and carbon dioxide are produced. • Example: Hydrochloric acid on reaction with sodium carbonate forms sodium chloride, carbon dioxide and water. 2HCl+Na2CO3 → 2NaCl+CO2+H2O  Sulfuric acid + Ferrous carbonate → Ferrous sulfate + water + carbon dioxide ■H2SO4 + FeCO3 -->  FeSO4 + H2O + CO2 • The salt that forms will depend on the specific acid and metal carbonate which were used in the reaction.
