(i) The polar covalent compound in gaseous state that does not conduct electricity is ammonia
(ii) A salt prepared by displacement reaction is Ferrous chloride
(iii) The number of moles in 11gm of nitrogen gas is 0.39
Gram molecular mass of nitrogen gas (N2) = 2(14) = 28
28 g of nitrogen gas = 1 mole
∴ 11 g of nitrogen gas = $\frac{1}{28}$ x 11 = 0.39
(iv) An alkali which completely dissociates into ions is lithium hydroxide
(v) An alloy used to make statues is bronze
