(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.

Sodium nitrate contains 0.3% iodine in the form of calcium iodate, Ca(IO3)2. After the sodium nitrate in the niter is dissolved and recrystallized, the remaining solution contains 9 g/Lsodium iodate, NaIO3(aq). The NaIO3 is converted to iodine when it reactswith sulfur dioxide and water.2NaIO3 + 5SO2 + 4H2O → Na2SO4 + 4H2SO4 + I2a. How many liters of sodium iodate solution that contains 9 g of NaIO3 perliter would be necessary to form 127.23 kg of iodine, I2?
