which statement correctly compares the mass of the reactants to the mass of the prodect in this chemical reaction CH4 + 2 O2 CO2+2 H2O A) the mass of the reactiant is one-four the mass of the products B) the mass of the reactants is half the mass of the products c) the mass of the reactant is equal to the mass of the products D) the mass of the reactant is twice the mass of the products.

Answer;

C. the mass of the reactant is equal to the mass of the products

Explanation; According to the Law of conservation of mass, the mass of the reactants should be equal to the mass of the products, and therefore, the number of atoms of each element on the reactants side should be equal to those on the products side. Mass cannot be created or destroyed in a chemical reaction. The total mass of substances taking part in a chemical reaction is conserved during the reaction. Thus, the number of atoms in a reaction remains the same.
