Answer 1

$<I>Hey there ✌⭐⭐☺⭐⭐☺⭐⭐☺⭐⭐☺⭐⭐ here's the answer......<I>$

✔ here the chemical formula of x is Fe2O3...

✔ this is a displacement reaction in which aluminium which is more reactive than iron displaces iron from Fe2O3.

✔. the reaction is:

Fe2O3 + 2Al ---------> Al2O3 + 2 Fe

hope it helps you ✔✔✌✌⭐⭐☺⭐⭐☺⭐⭐☺⭐⭐

Answer 2

(a) X is Fe2O3 i.e., Iron (III) Oxide

(b) The reaction involved is thermite reaction or aluminothermy.

(c) Fe2O3(s) + 2Al(s)→ Al2O3 (s) + 2Fe(s) + Heat

Ferric oxide Aluminium Aluminium Iron Oxide.
