Which gases will have the greatest rate of effusion?
The slowest rate of effusion will be exhibited by the gas with the highest molar mass. For example, Xenon will diffuse at a slower rate than Helium, and chlorine will diffuse at a slower rate than fluorine.
Which stateWhich statement about the effusion rates of nitrogen and oxygen is truement about the effusion rates of nitrogen and oxygen is true?
The rate of effusion is inversely related to the square root of the molar mass. Or stated another way, the larger or heavier the gas, the slower the effusion rate. Nitrogen gas (N2) has a molar mass of 28 g/mole and oxygen gas (O2) has a molar mass of 32 g/mole. Nitrogen will diffuse faster. rate N2/rate O2 = sqrt 32/sqrt 28 = 5.66/5.29 = 1.07. So, N2 effuses 1.07x faster than O2, or 7% faster. For more information on this, look up Graham's Law of Effusion.
What is the star Rigel's core made of?
Hydrogen and Helium, with the former decreasing and the latter increasing. Rigel is fusing H into He at a prodigious rate and in a million years or so will start to collapse as its fuel runs out.
What gases diffuses fastest under the same conditions of temperature and pressure?
because the molecules in a gas have no fixed position relative to one another and can move freely.
Explain why chlorine gas is collected at a slower rate than hydrogen?
Because the weight / density of chlorine is more than hydrogen. Hence the rate of displacement will be less than that of hydrogen.
How does the rate of effusion of sulfur dioxide compare to that of helium?
Sulfur dioxide diffuses at one-quarter the rate of helium
Which gases will have the greatest rate of effusion?
The slowest rate of effusion will be exhibited by the gas with the highest molar mass. For example, Xenon will diffuse at a slower rate than Helium, and chlorine will diffuse at a slower rate than fluorine.
The rate of effusion of Argon was measured to be 0.218mols at a certain temperature Calculate the rate of effusion of helium gas (Molar mass of Ar=40,Molar mass of Helium =4)?
50000
How can you compare the rates of effusion of two gases in a mixture?
The rate of effusion of two gases in a mixture is inversely proportional to the square roots of their molar masses.
What is the rate of effusion of nitrogen compared to oxygen?
The rate of effusion for nitrogen is higher.
What is the rate of effusion of a gas is inversely proportional to the square root of its molar mass?
Graham's law of effusion.
Explain the role of helium in stars?
The nuclear fusion of hydrogen produces helium and energy at the cost of some mass following the conversion rate e=mc^2
Can a red dwarf burn hydrogen?
A red dwarf fuses hydrogen into helium, just like any star, albeit at a very conservative rate.
What is Graham's law of effusion?
Graham's law of effusion states that the rate of effusion of a gas is inversely proportional to the square root of its molar mass. In other words, lighter gases effuse or diffuse at a faster rate than heavier gases under the same conditions.
How is the effusion rate of gas related to its molar mass?
A process related to diffusion is effusion, the process by which a gas escapes from a container into a vacuum through a small hole. The rate of effusion is also related to root mean square velocity-heavier molecules effuse more slowly than lighter ones. The rate of effusion-the amount of gas that effused in a given time- is inversely proportional to the square root of the molar mass of the gas.
Relationship between gas's molecular weight and speed of effusion?
Higher is the molecular mass lower is the rate of effusion, when mass increases by 4 times rate decreases to one half (Graham's law of diffusion).
Graham's law refers to?
Graham's law states that the rate of effusion of a gas is inversely proportional to the square root of its molecular weight.Graham's law states that the rate of effusion of a gas is inversely proportional to the square root of its molecular weight.
