Essential Understandings

Conservation of matter is represented in balanced chemical equations. A coefficient is a quantity that
precedes a reactant or product formula in a chemical equation and indicates the relative number of
particles involved in the reaction.
Essential Knowledge, and Skills
In order to meet this standard, it is expected that students will

transform word equations into chemical equations and balance chemical equations.
