Chapter 4: Quantities of Reactants and Products
... Check your answers: A properly balanced equation has the same numbers of atoms of each type (4 C, 12 H, and 14 O) in the products and reactants. The law of conservation of mass says that masses of the reactants must add up to the masses of the products, 284.16 g. This looks right. 12. Define the pro ...
