2. Given the balanced equation below: 4Al + 30, - 2Alz03 A student reacted aluminum in excess oxygen gas and produced only a 50% yleld of aluminum oxide. What is a possible reason for this result? Some aluminum was spilled during the lab. The products were contaminated with another substance. As a reactant, aluminum oxide was limiting. There was not enough oxygen gas.
