Explanation:

they are not connected at all

Answer 2

Answer:

assertion. Soda water is a mixture of carbon dioxide in water. In this solution, carbon dioxide is the solute and water is the solvent.

reason.The vapour pressure of air over water is 10 atm. 

The partial pressure of nitrogen =PN2=10079×10=7.9atm=7.9×760mmHg=6004 mm Hg

The partial pressure of oxygen PO2=10020×10=2.0atm=2.0×760mmHg=1520 mm Hg

According to Henry's law, 

PN2=KH(N2)×XN2

XN2=KH(N2)PN2=6.51×1076004=9.22×10−5

XO2=KHO2
