Creation of mass. Creation of mass. No extra mass allowed. New creation of mass is not allowed. Deduction of mass. No deduction of mass allowed. In a chemical reaction, mass cannot be created, mass cannot be destroyed. In a reaction, number of atoms should be same. Before and After. Example. Hydrogen plus Nitrogen is equal to Ammonia. Here, 2 is the subscript of hydrogen and nitrogen. We need to balance the number of atoms on both the sides. Reactants and Product. 2 Hydrogen atoms. 3 Hydrogen atoms. 2 Nitrogen atoms. 1 Nitrogen atom. 2 Nitrogen atoms. 1 Nitrogen atom. I need to balance nitrogen atoms on both the sides. 2 Ammonia atoms. 2 Hydrogen atoms. 3 Hydrogen atoms. 3 Hydrogen atoms. 6 Hydrogen atoms. I need to balance hydrogen atoms on both the sides. 3 Hydrogen atoms. Perfectly balanced chemical equation. Hydrogen plus Nitrogen equals Ammonia. The End.
