Propane gas reacts with oxygen gas to give carbon dioxide gas and water vapor (gas). If you mix propane and oxygen in the correct stoichiometric ratio, and if the total pressure of the mixture is 300 mm Hg, what are the partial pressures of propane and oxygen? If the temperature and volume do not change, what is the pressure of the water vapor after reaction?

partial pressures of propane =51mmHg

partial pressures of oxygen = 249mmHg

Pressure of water vapor = 171mmHg

Explanation:

The concept of raoult's law of ideal solution was used as shown in the attached file.

this means that the temperature of both substances will be equal

d₁ = displacement of tern from arctic to antarctic = 11000 miles

d₂ = displacement of tern from antarctic to arctic =   - 11000 miles

d = total displacement for the journey

total displacement for the journey is given as

d = d₁ + d₂

d = 11000 + (-11000)

d = 0 miles

t₁ = time of travel from arctic to antarctic = 3 months = 3 x 30 days = 90 days

t₂ = time of travel from antarctic to arctic = 3 months = 3 x 30 days = 90 days

t = total time of travel

total time of travel is given as

t = t₁ + t₂

t = 90 + 90

t = 180 days

average velocity is given as

average velocity = total displacement/ total time

v = d/t

v = 0/180

v = 0 miles/day
