Based on the reaction we will be able to tell what the limiting reagent is in the reaction. Furthermore, the theoretical yield of the, reaction also can be calculated when we identified the limiting reactants, theoretical yield is defined as the amount of product obtained when the limiting, reagent reacts completely. The mass of the mixture(1.123g) is equal to the mass of the excess(1.0146g) plus the mass of the limiting(0.1084g) is also equal to the mass of the precipitate(0.148g). To find the amount of remaining excess reactant, subtract the mass of excess reagent consumed from the total mass of excess reagent given. 20 17 >1.rlC8`8~MKTu,@^@'.
