BALANCED EQUATION

A description of a chemical reaction that gives the chemical formulas of the reactants and the products of the reaction, with coefficients introduced so that the number of each type of atom and the total charge is unchanged by the reaction. For example, a balanced equation for the reaction of sodium metal (Na(s)) with chlorine gas (Cl 2 (g)) to form table salt (NaCl(s)) would be 2 Na(s) + Cl 2 (g) = 2 NaCl(s), NOT Na(s) + Cl 2 (g) = NaCl(s).
