Question

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

Answer 1

Answer:

2. i)  Zinc oxide is considered an amphoteric oxide because it can react with both acids and bases.

11. Non-metals in general do not displace hydrogen from dilute acids because nonmetals have "tendency to accept electrons".

iii) Metals conduct electricity because the electrons inside the metal are relatively free to move. So when electricity is pass through metals, electrons carry electricity and spread it all over the metal.
