4.1 Writing and Balancing Chemical Equations – Chemistry
The nuers of H atoms on the reactant and product sides of the equation are equal, but the nuers of O atoms are not. To achieve balance, the coefficients of the equation may be changed as needed. Keep in mind, of course, that the formula subscripts define, in part, the identity of the substance, and so these cannot be changed without altering the qualitative meaning of the equation.
