reactants are rarely brought together with the exact amount needed. One reactant will be completely used up before the others. The reactant used up first is known as the limiting reactant. The other reactants are partially consumed
There are two methods used to find the limiting reactant. The first is to compare the actual mole ratio of the reactants to the mole ratio of the balanced chemical equation. The other method is to calculate the gram masses of the product resulting from each reactant. The reactant that y...
CHEMISTRY "LIMITING REACTANTS IN A RECIPE" (PLEASE HELP) « on: December 02, 2007, 02:00:18 AM » Hey all,I hve 2 do this chemisty project, and I was given sum recipe:1/2 cup sugar/1/2cup brown sugar, 1 1/3 stick margarin, 1 egg, 1/2 tsp salt, 1 tsp vanilla, 1...
This substance is the limiting reactant, and the other substance is the excess reactant. Identifying the limiting and excess reactants for a given situation requires computing the molar amounts of each reactant provided and comparing them to the stoichiometric amounts represented in the balanced ...
