Why Lesson Planet?
Newcomers to chemistry compare hydrogen peroxide to water, realizing that the difference of one oxygen atom significantly affects the chemical properties. Other pairs of compounds and their formulas are also examined. A few chemical reactions are set up to help learners identify evidence of a chemical reaction and understand the conservation of mass. Plenty of practice applying learned concepts is also provided through a series of assessment assignments. You can breathe easy using this resource as a guide to teaching chemical formulas.
