What gas effuses four times as fast as oxygen?
Helium is a gas that effuses four times faster than oxygen. This is because helium has a lower molar mass compared to oxygen, leading to faster effusion rates as per Graham's law of effusion.
How much faster do ammonia molecules effuse than carbon monoxide molecules?
Effusion goes as the inverse square root of the molecular weight (Graham's Law). The rest is simple algebra.
What technique can be used to separate a mixture in science?
One technique that can be used to separate a mixture is chromatography. In chromatography, the components of the mixture are separated based on their different affinities for a stationary phase and a mobile phase, allowing them to move at different rates and be identified.
What are some common effusion chemistry problems and how can they be resolved effectively?
Common effusion chemistry problems include inconsistent flow rates, contamination of samples, and difficulty in achieving accurate measurements. These issues can be resolved effectively by calibrating equipment regularly, using high-quality materials, and ensuring proper maintenance of the apparatus. Additionally, following standardized procedures and conducting thorough quality control checks can help minimize errors and improve the accuracy of results.
What is the ratio of the rates of diffusion of hydrogen gas to ethane gas C2H6?
According to Graham's Law of Effusion, the rate of diffusion of a gas is inversely related to the square root of the molar mass. Thus, smaller (lighter) gases diffuse faster than larger, heavier gases. Molar mass of H2 = 2 and molar mass of C2H6 = 30. Sqrt 2 = 1.41 and sqrt 30 = 5.48, so the ratio is 5.48/1.41 = 3.88 or H2 will diffuse almost 4x faster (3.88x) than ethane. The ratio of H2/C2H6 would be the inverse, or 1.41/5.48 = 0.257, meaning that the rate of diffusion of ethane is about 26% that of hydrogen.
Calculate the ratio of effusion rates for Ar and Kr?
The ratio of effusion rates for two gases is given by the square root of the inverse ratio of their molar masses. The molar mass of Ar is approximately 40 g/mol, and for Kr it is approximately 84 g/mol. So, the ratio of effusion rates for Ar and Kr is √(84/40) ≈ 1.3.
What is the ratio of effusion rates for the lightest gas H2 to the heaviest known gas UF6?
The ratio of effusion rates is inversely proportional to the square root of the molar masses of the gases. The molar mass of H₂ is about 2 g/mol, and the molar mass of UF₆ is around 352 g/mol. Therefore, the ratio of effusion rates for H₂ to UF₆ is approximately √(352/2) which is about 13.3:1.
What type of eruption causes pahoehoe lava?
High effusion rates
Why do gases effuse?
Gases effuse due to the random motion of their particles. This random motion leads to collisions with the walls of the container, causing the gas to escape through tiny openings. Effusion is a result of the gas particles moving at different speeds and escaping the container at varying rates.

How do you calculate the ratio of effusion rates for nitrogen times two and neon?
To calculate the ratio of effusion rates for nitrogen (N2) and neon (Ne), use Graham's law of effusion: Ratio = (Molar mass of neon / Molar mass of nitrogen)^(1/2) For neon (Ne) with a molar mass of 20.18 g/mol and nitrogen (N2) with a molar mass of 28.02 g/mol, the ratio of their effusion rates would be approximately √(20.18 / 28.02) ≈ 0.75.
