7.4 How to Write Balanced <strong>Chemical</strong> Equations<br />
1. Write a skeletal equation by writing correct<br />
chemical formulas for each <strong>of</strong> the reactants<br />
and products. Review Chapter 5 for<br />
nomenclature rules. (If a skeletal equation is<br />
provided, skip this step and go to Step 2.)<br />
2. If an element occurs in only one compound<br />
on both sides <strong>of</strong> the equation, balance it first.<br />
If there is more than one such element,<br />
balance metals before nonmetals.
