Step 5: Type one to two paragraphs that describe your models and explain the conservation of mass in the chemical reaction. a) Create a new blank document. Type your name at the top. b) Type one to two paragraphs that describe your models and relate them to the law of conservation of mass. Your document should: i identify the names of the reactants and products in the reaction. identify the number of molecules that make up the reactants and products iii. identify the type and number of atoms in each molecule of the reactants and products iv. explain what happens during the chemical reaction. V. explain how mass is conserved during the chemical reaction.
