The equation for Aluminum: a = 2c. The equation for Oxygen: 2b = 3c. Assuming a = 1, we get: c = a/2 ; c = 1/2. 2b = 3* (½) = 3/2 ; b = ¾.Tips for Balancing Equations . When balancing equations, remember chemical reactions must satisfy conservation of mass. Check your work to make certain you have the same number and type of atoms on the reactants side as on the products side. A coefficient (number in front of a chemical) is multiplied by all the atoms in that chemical.

These are the steps: First, count the atoms on each side. Second, change the coefficient of one of the substances. Third, count the numbers of atoms again and, from there, repeat steps two and three until you’ve balanced the equation. Here is an example of a chemical reaction that needs balancing: H 2 + O 2 → H 2 O.
