Question

5. A non metal 'x' which is the
largest constituent of air combines
with hydrogen in ratio 1:3 ratio in
presence of Fe as catalyst gives a
gas 'y! The gas 'y' is
O oxygen
O hydrogen
O nitrogen
O ammonia​

Answer 1

Answer: (a)Non-metal A is nitrogen gas N2 since, the percentage in air is largest, i.e., 78%. When N2 is heated with Hg in 1:3 ratio in presence of Fe as catalyst, it forms ammonia (NH3). Thus, B is ammonia (NH3) gas.
