Question

Give reason why
metals are good conductors, whereas non-metals are bad conductors of electricity.
2. Metals replace hydrogen from acids whereas non-metals do not.
3. An iron knife dipped in a blue copper sulphate solution turns the blue solution light green​

Answer 1

Answer:

Metals replace hydrogen from acids whereas non-metals do not.

Answer 2

Answer:

Metals replace hydrogen from dilute acids whereas non-metals do not. Non-metals are electronegative in nature. This means that their atoms can take up electrons and cannot lose them. Therefore, they do not evolve hydrogen on reacting with dilute acids.
