Complete the following reaction :
Al₂O₃ + 6HCl → 2AlCl₃ + ______

Correct option is D

The correct answer is (d) 3H₂O
Explanation:
. The balanced chemical equation is:
. Al₂O₃ + 6HCl → 2AlCl₃ + 3H₂O
. Aluminium atoms: 2 on both sides.
. Oxygen atoms: 3 in Al₂O₃, hence 3 molecules of H₂O are required.
. Hydrogen atoms: 6HCl provides 6 H atoms, which form 3 H₂O molecules.
. Chlorine atoms: 6 Cl atoms combine with aluminium to form 2AlCl₃.
Information Booster:
. Aluminium oxide (Al₂O₃) is an amphoteric oxide and reacts with acids as well as bases.
. This reaction is an example of acid–oxide reaction forming salt and water.
