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+3O2→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?

Oxygen gas reacts with powdered aluminum according to the following reaction:
4Al(s)+3O2(g)→2Al2O3(s)

Part A

What volume of O2 gas (in L), measured at 772 mmHg and 27 ∘C, is required to completely react with 54.6 g of Al?

Aluminum is mined as the mineral bauxite, which consists primarily of Al2O3 (Alumina). The aluminum can be refined by heating the bauxite to drive off the oxygen. 2 Al2O3 ---> 4 Al + 3 O2 How much aluminum is produced from 4.40 x 10^3 kg of Al2O3::::::I got 2.3 x 10^3 which is correct. b) The oxygen produced in part (a) is allowed to react with carbon to produce carbon monoxide. Write a balanced equation describing the reaction of alumina with carbon: Al2O3 + 3 C----->2 Al + 3 CO WHERE I AM STUCK IS HERE!!!! How much CO is produced from alumina in part (a) I tried 1.90x10^3kg CO and its wrong :(
