Here, we are required to determine which chemical formula is the product of the reaction between CaO and C02 given that matter is neither created nor destroyed.
The chemical formula of the product of this reaction is ; CaCO3.
The law of conservation of mass is the basis for the balancing of equations of chemical reactions.
The law states that matter( which is the building block of mass) can neither be created nor destroyed.
Therefore, in a reaction where one molecule of calcium oxide, CaO, and one molecule of carbon dioxide, CO2, combine in a chemical reaction to form one substance;
The chemical formula of the product of this reaction is ; CaCO3.
