Verified by Experts
When aluminium is heated in oxygen it forms aluminium oxide which is amphoteric in nature . `4Al + 3O_(2) to 2Al_(2)O_(3)` X is aluminium . Y is aluminium oxide Reaction of Aluminium oxide with hydrochloric acid: `Al_(2)O_(3)+6HCl to 2AlCl_(3)+3H_(2)O` REaction of Aluminium oxide with sodium hydroxide `Al_(2)O_(3)+2NaOH to 2NaAlO_(2)+H_(2)O`
