Question

Q2. Support the following statements with valid reason
i) Zinc oxide is considered an amphoteric oxide.
ii) Non-metals in general do not displace hydrogen from dilute acids.
iii) Metals conduct electricity​

Answer 1

Answer:

Reasons: Zinc oxide can react with both acid and bases, that's why it is considered as amphoteric oxide. Only more reactive compound can displace less reactive compound. Since, non-metals are less reactive than hydrogen. So, they can't displace hydrogen from diluted acids.

1.ans..Since ZnO act as both acid as well as base.

2.ans..Since non metal are less reactive than hydrogen.

3.ans..Due to highly electrolositive in nature and metals have their delocalised electrons which carry charge.
