PPT-Limiting Reactant/Reagent Problems

Consider the balanced equation for the production of ammonia N 2 3 H 2 2 NH 3 If you have 2 moles of nitrogen and 3 moles of hydrogen which reactant will be used up How much ammonia will you be able to make. Balancing Hints:. Balance the metals first.. Balance the ion groups next.. Balance the other atoms.. Save the non ion group oxygen and hydrogen until the end.. Balance . the following equations;. __Ca . (aka limiting reagent). Excess Reactant. Theoretical, Actual, and Percentage Yield. Limiting Reactant. (aka limiting reagent). Limiting reactant. : The substance you run out of first, that is consumed first--The reactant that . Reactants. Suppose that you are in a car factory. . In . order to assemble a car, 4 tires and 2 headlights are needed (among other things). . In . this example, imagine that the tires and headlights are reactants while the car is the product formed from the reaction of 4 tires and 2 . Stoichiometry. !. So far. In all our reactions, we assume both reactants get used up. We assume both reactants provided are pure. We rarely see these two.. Limiting reagents. Percent Purity. Percent Yield. Bon Appetite. Suppose you are a chef preparing . F. rench toast for a group of people. You make French toast the way you have always made it: . one egg for every three slices of bread. . You never waiver from this recipe, because the French toast will be either too soggy or too dry. There are 8 eggs and 30 slices of bread in the pantry.. Yes…it’s still stoichiometry…. Think about making grilled cheese…. To make a . decent . grilled cheese sandwich, you need two pieces of bread, 2 pieces of cheese, and 1 pat of butter.

Introduction. In any stoichiometry problem we start with a given quantity of a reactant or product. We use conversion factors and unit analysis to determine the quantities of the unknowns that react or form.. III.. . Limiting Reactants. . A. Why do reactions stop? Are all reactions 100% efficient?.
