1 Stoichiometry Ashley Saylor, Courtney Ford, Sam Kaplan

2 What is Stoichiometry? The portion of chemistry dealing with the numerical relationships in chemical reactions The calculation of quantities of substances involved in chemical equations

3 Mole-to-Mole Ratio Use coefficients from the balanced equation to make a ration Brownies 3 eggs 1 cup of milk 6 cups of flower 4 cups of sugar Ratio for: Eggs to sugar? Flower to milk? -Al:Cl - AlCl:Cl

4 Limiting Reagent & Excess Reagent Limiting- any reactant that is used up first in a chemical reaction Excess Reagent- The leftover reactant

5 Determining Limiting Reagent grams of and grams of given

6 Determining Excess Reagent

7 Theoretical & Actual Yield Theoretical Yield is the amount of product that could be formed Actual Yield is the amount of product that is formed

8 Calculating Theoretical Yield Your limiting reagent is 6.4 moles H2

9 Percent Yield Actual Yield divided by Theoretical Yield to get your percent accuracy

10 15g of reacts with 20g of. How much sodium chlorate can be formed?
