Answer 2

Amphoteric Oxide Formula

An amphoteric oxide is an oxide that can act as both an acid and a base. It can react with both acids and bases to form salts. The general formula for an amphoteric oxide is MxOy, where M represents a metal and x and y are integers representing the ratio of atoms in the compound.

Here are some examples of amphoteric oxides and their formulas:

1. Aluminum oxide: Al2O3 2. Zinc oxide: ZnO 3. Lead oxide: PbO 4. Chromium oxide: Cr2O3

These oxides can react with both acids and bases to form salts. For example, aluminum oxide can react with both acids and bases to form aluminum salts.
