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. Limiting Reagent. You will see the word "excess" used in this section and in the problems. It is used several different ways: . a) "compound A reacts with an excess of compound B" - In this case, mentally set compound B aside for the moment. Since it is "in excess," this means there is more than enough of it. Some other compound (maybe A) will run out first. . 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. Write an equation that describes making a grilled cheese sandwich. . Limiting Reactant. Limiting Reagent. The . reactant. that is totally used up during the chemical reaction. Limits. the amount of . product. produced . Excess Reactant. Excess Reagent. The . reactant. Percent Yield. When you make a peanut butter sandwich, you need 2 slices of bread and 1 tablespoon of peanut butter. The reactant that runs out first is called the limiting reactant. . Learning Goal . What is a limiting . r. eagent?. Steps for . determining the limiting reagent . Percent Yield. TeachWithFergy . Preview File. Please enjoy this preview of your Student Version of the lesson. . Some slides appear blank because they have been removed.. During a chemical reaction, the amount of each reactant will determine how much product is formed.. The . limiting reagent. is the reactant that is . used up first . in the reaction, thus determining when the reaction stops.. If it takes 500 bricks and 1000 boards to make a house, how many houses can you make from 1600 bricks and 2000 boards?. 2 houses, there are enough bricks for 3.2 houses. but only boards for 2 with our plans (reaction).. Advanced Stoichiometry Chapter 9, Section 2 (pages 312 – 318) Problem Set E (p. 314 # 1 – 3) Problem Set F (p. 317 # 1 – 3) Terms to Know and Understand: Limiting Reactant – the substance that controls the quantity of product that can form in a chemical reaction. LIMITING REAGENT PROBLEM:. A strip of Zn metal weighing 2.00 . g. is placed in an aqueous solution containing 2.50 . g. silver nitrate causing the following reaction to occur:. Zn (. s. ) + 2 AgNO.
