The reaction between solid sodium as well as iron (III) oxide is one in a series of reactions that inflates an automobile airbag 6Na(s) + Fe2)3(s) (produces) 3Na2O(s) +2Fe(s). If 100.0 g of Na and 100.0g of Fe2O3 are used in this reaction, determine the following:
a. limiting reactant
b. reactant in excess
c. mass of solid iron produced
d. mass of excess reactant that remains after the reaction is complete
