Steps in Balancing a Chemical Equation. Identify the most complex substance. Beginning with that substance, choose an element (s) that appears in only one reactant and one product, if possible. Adjust the coefficients to obtain the same number of atoms of this element (s) on both sides.
When atoms gain or lose electrons to yield ions, or combine with other atoms to form molecules, their symbols are modified or combined to generate chemical formulas that appropriately represent these species.
