  1. Double Cheeseburgers and Stoichiometry • 1 Double Cheeseburger needs 1 bun, 2 patties, 2 slices of cheese, 4 strips of bacon • For 5 Double Cheeseburgers how many units of each ingredient do I need? • Fill in the final column below with how many complete burgers I can make:

  2. Objectives • To understand the concept of limiting reactants • To learn to recognize the limiting reactant in a reaction • To learn to use the limiting reactant to do stoichiometric calculations • To learn to calculate percent yield

  3. A. The Concept of Limiting Reactants • Stoichiometric mixture • N2(g) + 3H2(g) 2NH3(g)

  4. A. The Concept of Limiting Reactants • Limiting reactant mixture • N2(g) + 3H2(g) 2NH3(g)

  5. A. The Concept of Limiting Reactants • For a Limiting reactant mixture the number of moles are not balanced to match the reaction equation • N2(g) + 3H2(g) 2NH3(g) • Limiting reactant is the reactant that runs out first • When the limiting reactant is exhausted, then the reaction stops

  6. B. Calculations Involving a Limiting Reactant

  7. Method 1: LAURA CHANG METHOD OF LR DETERMINATION • Grams of reactant A- convert to moles and divide by the coefficient g/(g/mol)= x/coeff • Grams of reactant B- convert to moles and divide by the coefficient (g/(g/mol)= x/coeff) The smaller value is the limiting reactant!

  8. Method 2:Calculations Involving a Limiting Reactant
