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) +...

Questions 1. Why is it necessary to write the balanced chemical equation for the reaction before completing any stoichiometry problems? The balanced equation makes it possible to Convert information about a reactant or product to quantitative data, per the Conservation of matter. 2. What does your percent yield indicate about the amount of copper actually formed in the reaction? Did you produce all the copper expected? Explain. 3. Based on your percent yield, indicate a source of error...
