  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 • Al:Cl • AlCl:Cl • 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?

  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 12.93 grams of and 108.80 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?
