2. EQs & Objectives ESSENTIAL QUESTIONS: OBJECTIVES:
How do chemical reactions show the law of conservation of mass?
OBJECTIVES:
8.5(D)  recognize that chemical formulas are used to identify substances and determine the number of atoms of each element in chemical formulas containing subscripts;
8.5(F)  recognize whether a chemical equation containing coefficients is balanced or not and how that relates to the law of conservation of mass.
