Question

When exposed to air, aluminum metal, A1- reacts with oxygen, O2, to produce a protective coating of aluminum oxide, Al2O3, which prevents the aluminum from rusting underneath. The balanced reaction is shown here: 4Al + 3O2 rightarrow 2Al2O3 What is the theoretical yield of aluminum oxide if 1 80mol of aluminum metal is exposed to 1 65mol of oxygen? Express your answer numerically in moles. In Part A. we saw that the theoretical yield of aluminum oxide is 0.900mol . Calculate the percent yield if the actual yield of aluminum oxide is 0.441 mol. Express your answer numerically as a percentage.
