Stoichiometry (How are masses of reactants and products related?) Model 1: The Balanced Chemical Equation As we saw in ChemActivity 19. a balanced chemical reaction can be interpreted in two ways. First, it can describe how many molecules of reactants are consumed in order to produce a certain number of molecules of products. Second, it can describe how many moles of reactants are consumed in order to produce the indicated number of moles of products. | 3 H2 (9) +...
