Answer 2

The reactivity series is:

Potassium

Sodium

Calcium

Magnesium

Aluminium

Zinc

Iron

Lead

Hydrogen

Copper

Etc

Hence copper being less reactive can't displace hydrogen from its solution of HCl.

Answer 3

The reactivity series is:

Potassium

Sodium

Calcium

Magnesium

Aluminium

Zinc

Iron
