13.16 as you need to use formula square root of ( 352.019/2.016)=13.16
Deserts are biomes where evaporation rates typically exceed precipitation rates. This imbalance leads to arid conditions with limited water availability, making deserts some of the driest places on Earth.
In dry climates, rates of evaporation exceed rates of precipitation. This leads to low humidity levels and a higher number of sunny days. As a result, there is limited condensation in these regions, contributing to their arid conditions.
rates of precipitation
Yes, abundant moisture and warm temperatures can result in high rates of chemical weathering because water and heat can facilitate chemical reactions that break down minerals in rocks. This process is known as hydrolysis and can lead to the breakdown of minerals into clay minerals and other dissolved ions.
The deserts biome is an example where evaporation rates often exceed precipitation rates. These regions receive limited rainfall, resulting in higher evaporation due to the intense heat and lack of moisture in the air.
High effusion rates
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.
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.
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.
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.
The rate of effusion of gases is inversely proportional to the square root of their molar masses. By comparing the molar masses of the two gases, you can determine which gas effuses faster. The gas with the lower molar mass will effuse more quickly.
The ratio of effusion rates between helium and radon gas is approximately √(Molar mass of gas 2 / Molar mass of gas 1), which in this case would be √(222 / 4) = √55.5 ≈ 7.46. This means that radon gas effuses approximately 7.46 times slower than helium gas under the same conditions.
The rain is heaviest in a hurricane near the center of the storm, which is called the eye wall. The eye wall is where the strongest winds and most intense rainfall occur, with rainfall rates reaching several inches per hour.
Well-known lending interest rates include the prime rate, the discount rate, and consumer rates for automobiles or mortgages.
Effusion goes as the inverse square root of the molecular weight (Graham's Law). The rest is simple algebra.
The variables involved in Graham's law are the molar mass of the gas particles and the rate of diffusion or effusion of the gas. The rate of diffusion or effusion is inversely proportional to the square root of the molar mass of the gas particles.
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.
