(a) Halogen, V reacts with hydrogen gas to form HV only when heated to 200 °C in the presence of a platinum catalyst. An aqueous solution of HV is formed when HV is dissolved in water. When aqueous silver nitrate solution is added to the HV solution, precipitate W is formed. With the aid of a balanced chemical equation, explain the reaction between precipitate W and concentrated ammonia solution. (i) The melting point of hydrogen fluoride, HF is higher than HV. Explain this phenomenon in terms of structure and bonding.
