Questiоn 4 — Limiting Reаctаnt: Thermite Reаctiоn The thermite reactiоn: Fe2O3(s) + 2 Al(s) → Al2O3(s) + 2 Fe(l) A chemist combines 100.0 g Fe2O3 and 54.0 g Al and allows the reaction to go to completion. What is the theoretical yield of Fe and what mass of the excess reactant remains unreacted? Molar masses: Fe2O3 = 159.69 g/mol; Al = 26.98 g/mol; Fe = 55.85 g/mol Warning: On a mass basis, 100 g Fe2O3 looks like the larger quantity — convert to moles before deciding which is limiting.
