1 Limiting Reactants

2 Limiting Reactant – limits the extent of the reaction Excess Reactant – left-over reactants For example: –For your birthday, you are given 10 bicycle frames and 15 wheels/tires –How many bicycles can be made? –What is the “limiting reactant”? –What is the “excess reactant”

3 6Na + Fe 2 O 3  3Na 2 O + 2Fe If 100.0g sodium and 100.0g iron(III) oxide are used in this reaction, determine: a. the limiting reactant

4 6Na + Fe 2 O 3  3Na 2 O + 2Fe If 100.0g sodium and 100.0g iron(III) oxide are used in this reaction, determine: b. the reactant in excess

5 6Na + Fe 2 O 3  3Na 2 O + 2Fe If 100.0g sodium and 100.0g iron(III) oxide are used in this reaction, determine: c. the mass of the solid iron

6 6Na + Fe 2 O 3  3Na 2 O + 2Fe If 100.0g sodium and 100.0g iron(III) oxide are used in this reaction, determine: d. the mass of the excess reactant that remains after the reaction is complete
