The Key to Balancing Chemical Equations The ultimate goal for balancing chemical equations is to make both sides of the reaction the reactants and the products equal in the number of atoms per element This stems from the universal law of the conservation of mass which states that matter can neither be created nor destroyed A balanced equation is a chemical equation in which mass is conserved and there are equal numbers of atoms of each element on both sides of the equation We can write a chemical equation for the reaction of carbon with hydrogen gas to form methane CH4 CH 4 C s 2Catoms H2 g 2Hatoms CH4 g 1 Catom 4H atoms C s H 2 g CH 4
