WebIn much the same way, a reactant in a chemical reaction can limit the amounts of products formed by the reaction. When this happens, we refer to the reactant as the limiting reactant (or limiting reagent).The amount of a product that is formed when the limiting reactant is fully consumed in a reaction is known as the theoretical yield.In the case of our hot dog … WebThe equation says that 1 mol CaCO 3 reacts with 2 mol HCl. So 0.050 mol CaCO 3 reacts with 2 x 0.050 mol of this HCl = 0.10 mol. Now compare the numbers of moles. The calcium carbonate needs 0.10 mol HCl; you have 0.15 mol. So the acid is in excess. The limiting …
