2. The reaction between solid sodium and iron(III) oxide is one in a series of reactions that inflates an automobile airbag. 6Na(s) + Fe2O3(s) 3Na2O(s) + 2Fe(s) If 100.0 g Na and 100.0 g of Fe2O3 are used in this reaction, determine (a) the limiting reactant; (b) the mass of solid iron produced; and (c) the percent yield if 62.3 g of solid iron was isolated.
