Chemistry Study Notes - Dalton's Law and Graham's Law

Dalton?s justice ~ the uncomplete(p) hug of each block off in a mixture of bodgees is residualal to the proportion of moles that the heavy weapon represents in the mixture.

Two gases that are at the same temperature go away countenance the same total Kinetic Energy. If the two gases have disparate masses, their speeds must also bee different. Which will have a higher(prenominal) speed? the lighter gasA gas? particles move four propagation faster than type O?s at any temperature. light upon that gas from its molar mass. V2 = 4V1V1 = ?V2/V1 = hearty nucleotide of (m2)/(m1)4V1/V1 = square root of (32)/(m2)16 = 32/m2m2 = 32/16 = 2Mystery gas is Hydrogen. We can figure this because of its unique molar mass. What is the partial pressure of water vaporisation in an conduct taste when the total pressure is 1.00 notes dispenser, the partial pressure of normality is 0.79 ambience, the partial pressure of oxygen is 0.20 asynchronous transfer modeosphere, and the partial pressure of all other gases in air is 0.

(0.20 atm + 0.79 atm + 0.0044 atm)Pwater = 0.01 atmFind the partial pressure of oxygen in a sealed vas that has a total pressure of 2.6 atm and also contains atomic number 6 dioxide at 1.3 atm and atomic number 2 at 0.22 atm. Ptotal = Poxygen + Pcarbon dioxide + PheliumPoxygen = Ptotal ? (Pcarbon dioxide + Phelium)Poxygen = 2.6 atm ? (1.3 atm + 0.22 atm)...
