Al2O3
A passive aluminum oxide layer will form on the surface of the aluminum, when it is in the presence of Oxygen (Al2O3). This then goes on to protect the rest of the aluminum from further oxidisation as the layer will remain in place, bonded to the aluminum.
Fe2O3 + 2Al ===> Al2O3 + 2FeIn this reaction the number of moles of Al2O3 produced is dependent on the number of moles of Fe2O3 and Al that one starts with. For every 1 mole Fe2O3 and 2 moles Al, one gets 1 moles of Al2O3.
Al and S combine to form aluminum sulfide, Al2S3
Burning of aluminum in oxygen (air): 4Al + 3O2 → 2Al2O3
Aluminum oxide is formed by combining the aluminum mass consumed by burning with oxygen from the air to form aluminum oxide, with formula Al2O3.

2Al + Fe2O3 -> Al2O3 + 2Fe the thermite reaction-
Al and S combine to form aluminum sulfide, Al2S3
Al2O3+3H2O=2Al(OH)3

The reaction is with aluminium:Fe2O3 + 2 Al = 2 Fe + Al2O3
1.5 moles of O2 react with 2 moles of Al 2Al + 1.5 O2 = Al2O3.
Burning of aluminum in oxygen (air): 4Al + 3O2 → 2Al2O3
We know that Al2O3 is the chemical formula for aluminum oxide.
