How is matter and energy conserved in this chemical reaction?

The ratio of reactants and products in a chemical reaction is called chemical stoichiometry . Stoichiometry depends on the fact that matter is conserved in chemical processes, and calculations giving mass relationships are based on the concept of the mole . One mole of any element or compound contains the same number of atoms or molecules, respectively, as one mole of any other element or compound.
