(a) Covalent bonding is present in ammonia as shown below —
(b) The formula of liquid ammonia is NH4OH.
The aqueous solution of ammonia [NH4OH] is a weak base. It dissociates partially to give hydroxyl ions [OH1-].
The basic nature of NH4OH is due to the presence of hydroxyl ions [OH1-].
NH3 + H2O ⟶ NH4OH
NH4OH ⇌ NH4+ + OH-
