  1. Chemical Reactions Introduction LT 5C:Describe how the Law of Conservation of mass determines what reactants and products will be in a reaction. Identify the reactants and the products of a chemical reaction. Determine how many atoms are reacting or being produced, given the formula of a compound using subscripts and coefficients Balance a chemical equation given the reactants and products of a reaction Justify how chemical reactions obey the Law of Conservation of Mass Vocabulary: Chemical Reaction Reactants Products Chemical Equation Law of Conservation of Mass Subscript Coefficient
