When exposed to air, aluminum metal, Al, 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+3O2รขย†ย’2Al2O3

Part A

What is the theoretical yield of aluminum oxide if 2.80 mol of aluminum metal is exposed to 2.40 mol of oxygen?

aluminum is mined as the mineral bauxite, which consists primarilyof Al2O3 (alumina). The aluminum can be refined by heating thebauxite to drive off the oxygen:

2Al2O3(s) ----> 4Al(s) + 3O2(g)

part a) the aluminum produced from 2.60 x 10^3 kg of Al2O3 is 1.38x 10^3 kg.

the oxygen produced in part a) is allowed to react with carbon toproduce carbon monoxide. write a balanced equation describing thereaction of alumina with carbon.

how much CO is produced from the alumina in part a?
