chemistry-1 Final The maximum amount of product that can be formed in a chemical reaction can be calculated from the number of moles of the reactant in excess If a compound contains three elements, the empirical formula cannot be determined by performing analyses for just two of those elements You cannot calculate the theoretical yield for a reaction, knowing the starting amounts of each reactant and a balanced chemical reaction If you know the mole ratio of a compound, you need more information to determine the molecular formula The total number of moles of reactants is necessarily the same as the total number of moles of products in a balanced chemical reaction If you know the molecular formula of a compound, and have access to a periodic table you can determine the formula weight Combustion in air involves a reaction with oxygen Zinc (I) phosphate will have the formula Zn?(PO?)
