Precipitation reaction is a chemical reaction used to separate the insoluble solid to the aqueous solution. This is a technique that is usually used to separate the impurities. By knowing the right chemical to react with, only the pure acid will react and dissolve with ether. The impurity will be precipitated and will settle to the bottom.
To answer this, we use Raoult's Law where the partial pressure is equal to the product of the fraction of the gas in the mixture and its total pressure. Also, we use Dalton's Law of Partial Pressure where the total pressure is equal to the sum of the partial pressure of the gases in the mixture.
Ptotal = 73.44 + 128.52 + 2.04 = 204 atm
201.96 = x (204)
x = 0.99
CO2 will be the first to boil because it will be the first to warm up because it is the closest temperature to 0
