What is the composition of gases in the tanks used by the scuba divers?

View answer and explanation

Correct option: B

11.7 \%

helium

56.2 \%

nitrogen

32.1 \%

oxygen

Option B (

11.7 \%

helium

56.2 \%

nitrogen

32.1 \%

oxygen) is the correct composition of gases in scuba diving tanks, balancing oxygen needs and nitrogen narcosis risks.

Consider the solution of ethanol. In it Assertion: Isotonic solutions don't show net phenomenon of osmosis.

Reason: Isotonic solutions have equal osmotic pressure at constant temperature. 0.2 molal aqueous solution of a monobasic acid is 60% ionised. If Kb for water is

0.52\,K\,kg\,mo{l^{ - 1}}

then the boiling point of the solution will be The vapour pressures of pure liquids
