Al is limiting reagent moles of fe formed = 0.080 mol mass of fe = 56 x 0.080 = 4.48 g 6 what mass of aluminium chloride is formed when 13.5 →g of aluminium reacts with 42.6 g of chlorine? Define limiting and excess reactants. 12.3.1 explain how the amount of product in a reaction is affected by an insufficient quantity of any of the reactants.
To determine the grams of excess reagent, subtract the amount you need from the amount that you have, then using the molar mass, convert the moles left to grams. Web c) how much of the excess reagent is left over in this reaction? Web limiting reactants in solutions. 12.3.1 explain how the amount of product in a reaction is affected by an insufficient quantity of any of the reactants. Once the limiting reactant gets used up, the reaction has to stop and cannot continue and there is extra of the other reactants left over.
