Answer to Question 1

ANS: D
Oxygen concentrators are devices that produce enriched oxygen from atmospheric air. Thus, ox-ygen and water vapor diffuse through these membranes faster than nitrogen.

Answer to Question 2

ANS: B
Fractional distillation generates bulk oxygen. Molecular sieves and semipermeable membranes are used in oxygen concentrators. The combustion of natural gas produces carbon dioxide.
