Answer» Question 59 A non-metal A, which is the largest constituent of air, when heated with $H_{2}$ in 1:3 ratio in the presence of catalyst $Fe$ , gives a gas B. On heating with $O_{2}$ , it gives an oxide C. If this oxide is passed into water in the presence of air it gives an acid D, which acts as a strong oxidising agent. (a) Identify A, B, C and D (b) To which group of periodic table does this non-metal belong?
