1.	State reason for the following :(i) Non-metals cannot displace hydrogen from the acids.(ii) Hydrogen is not a metal, yet it is placed in the activity series of metals.(iii) Aluminum is more reactive than iron, yet its corrosion is less than that of iron.
Answer» (i) Non-metals are electron accepters, they cannot supply electrons so as to convert H⁺ ion to H₂(g). (ii) Like metals, hydrogen can lose an electron to form positive H⁺ ion. (iii) Aluminium is covered with a strong Protective layer of oxide which protects the metal from further corrosion.
