Q

Magnesium with HCL

A

rapid reaction with bubbles produced at steady rate

17
Q

Zinc with HCL

A

Slow reaction with bubbles produced slowly

18
Q

Copper with HCL

A

No reaction even with concentrated acid

19
Q

Displacement reaction

A

A reaction in which one atom or ion (usually a metal) replaces another atom or ion in a compound

20
Q

Why does aluminium lack reactivity

A

Unreactive with water and acids
Because the surface of freshly made aluminium gets coated with a layer of aluminium, oxide by reaction with oxygen in the air

This layer is fairly unreactive and is resistant to corrosion
