PPT-Limiting Reactants and Percentage Yield

vocab Limiting reactant the one that runs out first limits the amount of product that can be made Excess the one with reactant leftovers not used up completely What it looks like C O 2 CO. FIGURE L 17.1 The basic principles of atomic theory (g) + H(g) (g)In this case, he or she cannot simply add another atom of nitrogen and take an atom of hydrogen away from the chemical formula for amm (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 . 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. 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. . stoichiometry. to solve problems where there may be one reactant in limited amount, which thus affects how much product can be produced.. The Limiting Reactant. Stoichiometry. Review. Write a balanced chemical equation. Percentage Yield and Percentage Purity. It is assumed in a chemical reaction that our products are always produced 100% pure. That means whatever our reactants are will all be reacted and turn into pure product without any by-products. 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. .

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. 9-3. 9-3 Learning Targets. Identify the limiting reactant in a chemical equation. Identify the excess reactant and calculate the amount remaining after the reaction is complete. Calculate the mass of a product when the amount of more than one reactant is given. III.. . Limiting Reactants. . A. Why do reactions stop? Are all reactions 100% efficient?. Reactions might . stop. for a number of reasons including: . consumption. of one or multiple reactants; occurrence of side reactions; .
