Which of the following is different from other oxide ?Al2O3K2OZnOBeO

The oxide that is different from the others is Al2O3. Here's why:

1. Al2O3, or Aluminium Oxide, is an amphoteric oxide. This means it can act as both an acid and a base. It reacts with both acids and bases to produce salt and water, showing both acidic and basic properties.

2. K2O, or Potassium Oxide, is a basic oxide. It reacts with water to form potassium hydroxide, a strong base.

3. ZnO, or Zinc Oxide, is also amphoteric like Al2O3. It can react with both acids and bases.

4. BeO, or Beryllium Oxide, is also amphoteric. It can react with both acids and bases.

So, the one that stands out is K2O because it is only a basic oxide, while the others (Al2O3, ZnO, BeO) are amphoteric oxides.
