A balanced equation for each step of preparation of calcium carbonate has to be written. Concept introduction: There is a law for conversion of mass in a chemical reaction i.e., the mass of total amount of the product should be equal to the total mass of the reactants. The concept of writing a balanced chemical reaction is depends on conversion of reactants into products. First write the reaction from the given information. Then count the number of atoms of each element in reactants as well as products. Finally obtained values could place it as coefficients of reactants as well as products.
