The Fundamental Ideas in Chemistry
... Recall that chemical reactions can be represented by word equations or symbol equations. Describe how no atoms are lost or made during a chemical reaction so the mass of the products equals the mass of the reactants. Calculate the mass of a reactant or product from information about the masses of th ...
