Balancing Equations (Sec 4 SE and Sec 4 ST)

In this lesson, we review the basic principles of balancing equations. Foremost, students must bear in mind the Law of Conservation of Matter, or in other words, that elements must be equal on the reactant and product sides of any chemical equation. Using coefficients (not subscripts!), students can balance elements to ensure the law is followed and the reaction balanced.

Learning Goals:

  • To balance a chemical equation
