Balancing Equations

A very important aspect of this lesson is for you to learn how to balance equations. It may come very easily and quickly to you, or it may take an awful lot of hard work. You may have had previous experience with this and only need review. In any case you need to make sure you get sufficient practice. I will show you how to balance some equations and work through several examples and then have you take the time to get a lot of practice. Each succeeding example adds some degree of difficulty or complexity.

The equations to be balanced in these examples are also shown in example 3 in your workbook. If you already have experience balancing equations, you might want to look at those first and try balancing them. Then look at the worked-out examples of those (if any) that give you trouble.

What we need to do is come up with the numbers that have to go in front of the formulas for each of these chemicals in order to represent the same total number of atoms on each side of the arrow. Those numbers are called coefficients.
