C12H22O11 + 12 O2 Â® 12 CO2 + 11 H2O This illustrates the methods used for writing balanced reaction equations: 1  Determine the reactants and products. In this case, the products are CO2 and H2O, determined by common sense. 2  Apply the fundamental principle of conservation of atoms.
A chemical equation is balanced when the a. coefficients of the reactants equal the coefficients of the products. b. same number of each kind of atom appears in the reactants and in the products. c. products and reactants are the same chemicals. d. subscripts of the reactants equal the subscripts of the products.
