Limiting Reactants

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”

6Na + Fe2O3  3Na2O + 2Fe If 100.0g sodium and 100.0g iron(III) oxide are used in this reaction, determine: a. the limiting reactant

6Na + Fe2O3  3Na2O + 2Fe If 100.0g sodium and 100.0g iron(III) oxide are used in this reaction, determine: b. the reactant in excess

6Na + Fe2O3  3Na2O + 2Fe If 100.0g sodium and 100.0g iron(III) oxide are used in this reaction, determine: c. the mass of the solid iron

6Na + Fe2O3  3Na2O + 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
