A balance chemical equation is an equation describing a chemical reaction with the right number of molecules to cancel out each side of the equation. For example: H2 + O2 —> H2O Make sure the number of molecules in your reactants equal the number of molecules in your product 2H2 + O2 —> 2H2O (4 hydrogens and 2 oxygens = 4 hydrogens and 2 oxygens)
