What happens when aluminium and oxygen combine?

Answer 1

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.

Answer 2

When aluminum and oxygen combine, they form aluminum oxide. This process is known as oxidation. Aluminum oxide forms a thin, protective layer on the surface of the aluminum, which helps prevent further corrosion and degradation.

Answer 3

Aluminum plus oxygen gives aluminum oxide:

4 Al + 3 O2 --> 2 Al2O3

Answer 4

The chemical reaction (without importance in industry) is:
4 Al +3 O2 = 2 Al2O3

Answer 5

Al2O3 is Aluminum Oxide.

Answer 6

Aluminium Oxide : Al2O3 :)

Answer 7

No reaction
