Question

What happens when aluminium is heated at ${800}^{0}C$?

Statement 1: Aluminium reacts with air to form chlorides.

Statement 2: On heating aluminium at ${800}^{0}C$, it burns to form its oxides and nitrides.

• A. Statement 1 and statement 2 are true.
• B. Statement 1 and statement 2 are false.
• C. Statement 1 is true and statement 2 is false.
• D. Statement 1 is false and statement 2 is true.

Answer 1

The correct option is D

Statement 1 is false and statement 2 is true.

On heating aluminium at ${800}^{0}C$, it burns very brightly forming its oxide and nitride.

$4Al+3O_2\to 2A{l}_2{O}_3$ (Aluminium Oxide)

$2Al+N_2\to 2AlN$ (Aluminium Nitride)
