Evaluating Chemical Expressions

Unit 5: Stoichiometry
Lesson 1 of 8

Objective: Students will be able to determine how many atoms of each element are in a chemical expression.

Big Idea: Subscripts indicate how many atoms for an element are in a compound, and coefficients indicate the quantity of molecules or formula units. Multiply the coefficient by the subscripts to know how many atoms of each element are contained in a chemical express
