How does aluminium react with air?

1.	How does aluminium react with air?
Answer» Solution :ALUMINIUM is not attacked by DRY air. But it gets a coating of aluminium oxide in the presence of moist air. The oxide film PROTECTS aluminium from further corrosion. When heated aluminium burns brightly in air to form aluminium oxide . `4AI_((s)) +3O_(2(g)) overset ("BURN ") to 2 AI_(2) O_(3(s))`
