Question

give reasons :-
(i) metals conduct electricity
(ii) ZnO considered as amphoteric oxide ​

Answer 1

1. metal have free electrons that's why it will conduct electricity.
2. zinc oxide is considered as amphoteric oxide because it will react both acid as well as base and have been both properties acidic as well as base.

➊

Metals conduct electricity because the electrons inside the metal are relatively free to move. So when electricity is through metals, electrons carry electricity and spread it all over the metal. The mobility of electrons is the reason why metals conduct electricity.

➋Zno is an amphoteric oxide,because it can react with both acids and bases. while in general most oxides only react with acids alone due to its basic nature. Amphoretic oxides contradicts the Bronsted –Lowrey theory of acids and bases
