Explanation:
Aluminuim is a highly reactive metal and Hydrogen falls under in the least reactive metals. Thus, this is a displacement reaction. Since, Aluminuim is more reactive, it displaces Hydrogen and reacts with Oxygen.
If you are wondering about the numbers in the subscript:
The valence electrons of Aluminum(Al) is 3 and that of Oxygen(O) is 2. Hence, when Aluminuim reacts with Oxygen, the number of valence electrons is crossed with the other element and hence, we get Al²O³ and Hydrogen is left out. Hydrogen itself is a diatomic element, which forms a covalent bond with another hydrogen to form H².
