Chemistry in a Nutshell

Practice problems for balancing chemical equations using the trial and error AND algebraic methods. The algebraic method is a must for equations that are difficult to balance. Answers are shown for each problem.

Although the algebraic method can be used to balance any chemical equation, I personally use the trial and error method for beginner or intermediate level problems and the algebraic method for hard or time-consuming problems. To learn about the trial and error method of balancing chemical equations, see this: /youtube/video/Vtu5aI2MJgM
