Class began with the ChemCatalyst from the Lesson 72 PowerPoint. With the lesson focusing on balancing chemical equations, we worked through the ChemCatalyst equation with a focus on differentiating coefficients and subscripts (slides 11 and 12). We used the remainder of the class period to practice balancing equations.

For students who would like additional instruction around balancing equations and enjoy learning by watching videos, I recommend Tyler DeWitt’s videos Introduction to Balancing Equations (above) and Balancing Chemical Equation Practice Problems (below):
