Question

11. The amphoteric oxide among the following is
K20
CO2
ZNO
CаO​

Answer 1

Answer:

ZnO, Zinc oxide is an ampotheric oxide.

Explanation:

Amphoteric oxide : Generally, the oxides formed by metals are basic in nature while oxides formed by non- metals are acidic in nature. Some oxides are neutral in nature. But, some oxides act as both acidic and basic oxide and such oxides are known as Amphoteric oxides.

Examples: Aluminium oxide (Al2O3), Zinc oxide (ZnO), Tin oxide (SnO), Lead oxide (PbO) are amphoteric oxides. They neutralise acidic and basic oxides.

So the correct option is C,ZnO.

Answer 2

correct option is 3

ZnO

Zinc oxide, or ZnO, is an amphoteric oxide.

Explanation:

Amphoteric oxide: Oxides created by metals are generally basic, whereas oxides formed by non-metals usually acidic. Some oxides are naturally neutral. Some oxides, however, operate as both acidic and basic oxides, and are referred to as amphoteric oxides.

Amphoteric oxides include aluminium oxide (Al2O3), zinc oxide (ZnO), tin oxide (SnO), and lead oxide (PbO). Acidic and basic oxides are neutralized by them.

As a result, C,ZnO is the right answer.
