Question

O2 is not the raw material in the manufacture of- (a) HNO3 (b) H2SO4 (c) NH3 (d) SO3​

Answer 1

c) NH3 is correct option

Answer 2

Oxygen is not a raw material in the manufacture of ammonia.

• Ammonia does not contain oxygen atoms so, oxygen is not the raw material for the manufacture of ammonia.
• Ammonia is manufactured by the reaction of one mole of nitrogen gas and three moles of hydrogen gas at high temperatures and pressure.
• The balanced chemical reaction is as follows-
• $N_2+3H_2\rightarrow 2NH_3$.
• Hence the correct option is c.
