Question
Assuming ideal behavior, which of the following changes will NOT affect the total pressure of gas in a container, assuming all other factors remain constant? The frequency of collisions of molecules with the walls is increased The average velocity of the molecules is lowered. The temperature of the sample is altered. Half of the molecules are replaced by an equal number of molecules of a gas with a different molecular weight The total number of molecules is altered. A 2.5 ml bubble is released at a depth of 178 feet in a lake where temperature is 4.0 degree C. What is the volume (mL) of the bubble at the surface the total pressure is 6.4 atm and the when the pressure is 758 torr and 20 degree C? 18 mL 17 ml 15 mL 14 mL 12 mL Arrange the following gases in order of increasing rate of effusion. CO_2Explanation / Answer
Arrange the following gases in order of increasing rate of effusion.
A) CO2: < Ar < 02 < C2H6 ------ANSWER
8) C2H6 < 02 < Ar <
C) CO2 < 02 < C2116 < Ar
D) C2H6 < Ar < 02 < CO:
E) CO2 < 02 < Ar < C2H6
indicated by Graham's law the rate of radiation is conversely relative to the square foundation of the molar mass of the gas,
that implies as littler the molar mass so higher the rate of EFFUSION is
Ar molar mass =39.948 u ± 0.001=40 g/mol
the molar mass of C2H6= 30.07 g/mol
the molar mass of 02= 31.99 g/mol
the molar mass of c02= 44.01 g/mol
