Question

why are covalent compounds are genrally poor
conductors of electricity? What are amphoteric oxides ?
why non melals do not displace hydrogen from dilute acid
​

Answer 1

Answer:

Covalent compounds are generally poor conductors of electricity because they do not produce ions in solution or on melting.

amphoteric compound is a molecule or ion that can react both as an acid and as a base.

The reason why non-metals do not displace hydrogen from dilute acids is because unlike metals, non-metals do not have a tendency to lose electrons but to gain electrons. ... Only those metals which are reactive than hydrogen will displace H2 from acids.

Answer 2

Answer:

amphoteric oxides are react with both acids and base and gives salt
