Answer 2

out of these gallium oxide is amphoteric in nature as it can react with both acids and bases to form corresponding salts and water

other amphoteric oxides: zinc oxide , aluminum oxide , lead oxide

when gallium oxide react with acid

ga2O3 + HCl -------> gacl3 +H20

when gallium oxide react with base

ga2O3+ NaOH ------->NaGaO2 + H2O(sodium gallate)
