Answer 1

Answer:

2 is right answer

Explanation:

bcz both gases have different chemical formula.

Answer 2

Answer:

The number of components in the system is 2.

Explanation:

A system containing O2 and N2 have one phase (gas) and two components.

The air is a mixture of a number of gases. The major components are oxygen and nitrogen with approximate proportion of 20% to 79% by volume at 298 K. The water is in equilibrium with air at a pressure of 10 atm. At 298 K, if the Henry's law constants for oxygen and nitrogen at 298 K are 3.30×107 mm and 6.51×107 mm respectively, calculate the composition of these gases in water.
