CH301 Chapter 3 Limiting Reagents: Consider an assembly line for a car: Each chassis needs 4 wheels and 1 windshield. If I have 2 chassis, 8 wheels, 2 windshields, how many cars can be assembled? What if I have 2 chassis, 7 wheels, 2 windshields? What if I have 2 chassis, 7 wheels, 1 windshield? What if I have 10 chassis, 55 wheels, 5 windshields? Recognizing Limiting Reactant Problems MUST have a balanced equation!! Work the problem in moles - even if the final answer is in g. The amounts of at TWO reactants will be given: one is the limiting reagent. If there is NO information about the amounts of other reactants, assume they are present in excess - so they will not be limiting. Working Limiting Reactant Problems 1. Convert given amounts of reactants to moles. 2. Use amount of moles of one reactant to calculate amount of product. 3. Repeat for the amount of moles for the second reactant. 4. The SMALLEST answer is the correct choice for amount of product made.
