Limiting Reactant A.K.A. Stoichiometry
How do we determine which reactant limits the product? One reactant remains while the other is consumed in a reaction Mole ratio will help determine the limiting reaction Need to create a conversion pathway
Two! The chocolate syrup limits the recipe!
Which reactant is the limiting reactant? Step 1 Moles of reactant Moles of product • Which reactant remains when 6.70 mole Na reacts with 3.2o moles of Cl2 • 2 Na + Cl22 NaCl
2 Na + Cl22 NaCl Step 1 Step 1 Cl2 is the Limiting Reactant!

Limiting Reactant and Mass-Mass Conversions • Which reactant is the limiting reactant when 3.5 g Cu reacts with 6.0 g AgNO3? • Cu + AgNO3 Cu(NO3)2 + Ag; balanced? • Cu + 2 AgNO3 Cu(NO3)2 + 2 Ag
Create a Conversion PathwayCu + 2 AgNO3 Cu(NO3)2 + 2 Ag Step 1 Step 2 Step 3 Moles of Reactant Mass of Product Mass of Reactant Moles of Product We have 3.5 g Cu and 6.0 g AgNO3
Cu + 2 AgNO3 Cu(NO3)2 + 2 Ag Silver nitrate is the limiting reactant!
