The coefficient for aluminium is 4.

Explanation:

We have the following chemical reaction:

Al + O₂ → Al₂O₃

In order to balance the chemical equation the number of the atoms entering the reaction should be equal to the number of atoms leaving the reaction.

2 Al + 3/2 O₂ → Al₂O₃

However we need integer numbers so we multiply everything with 2.

4 Al + 3 O₂ → 2 Al₂O₃

The coefficient for aluminium is 4.
