Question

Calcium carbonate decomposes on heating to form calcium oxide and carbon dioxide when 10 gram of calcium carbonate is decomposed completely than 5.6 gram of calcium oxide is formed calculate the mass of carbon dioxide what law of chemical combination will you use in solving this problem

Answer 1

Answer:

law of conservation of mass

Explanation:

because here in this reaction,

dissociation of product is complete

therefore, total mass of reactants is equal to total mass of product.

I. e., 10=5.6+4.4
