DO NOW VL: 0

ESSENTIAL QUESTIONS: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.
