Question

Q.1 Which of the following is not obtained as a component during the isolation of components by fractional distillation of air?

(a) Carbon dioxide

(b) Argon

(c) Carbon Monoxide

(d) Oxygen

Answer 1

(a) Carbon dioxide

(a) Carbon dioxide is the correct answer

Hope it is help for you

Answer 2

Answer:

(a) Carbon dioxide

Explanation:

• The gases in air can be separated via fractional distillation, which involves liquefaction of the gases as the initial stage. $CO_{2}$ freezes at  $79^{o} C$  and is eliminated, whilst $O_{2}$  $N_{2}$ liquefies. It doesn't liquefy in any way.

• It's vital to remember that fractional distillation is an energy-intensive technique for isolating gas from air. The energy used to manufacture $N_{2}$ emits a considerable amount of carbon dioxide ($CO_{2}$)
