The average translational kinetic energy and the rms speed of molecules in a container of oxygen at a particular temperature are 6.70 × 10-2j and 416 m/s, respectively, what are the corresponding values when the temperature is doubled? Kav = Vrms m/s Need Help? Watcht
Neon has 10 electrons, and xenon has 54 electrons. Noble gases tend to be relatively unreactive and both atoms are electrically neutral. However, xenon can form xenon difluroride, xenon tetrachloride, and a few other molecules. Explain why xenon can bond atoms to form some molecules but there are no known neon a. compounds. b. Which element (Xe or Ne) do you think has a greater chance of forming a momentary dipole? Explain and draw a diagram that shows the distribution...

The kinetic theory of gases states that the kinetic energy of a gas is directly proportional to the temperature of the gas. A relationship between the microscopic properties of the gas molecules and the macroscopic properties of the gas can be derived using the following assumptions: The gas is composed of pointlike particles separated by comparatively large distances. The gas molecules are in continual random motion with collisions being perfectly elastic. The gas molecules exert no long-range forces on each...

Come ow hack incessary. 6. 0.060 kg of monatomic neon (Ne) are confined in a 600 em' cylinder at a temperature of 227 What is the pressure in the cylinder? At what temperature would these molecules have a root-mean-square velocity of 1200...
The average kinetic energy of the molecules in a gas sample depends only on the temperature, T. However, given the same kinetic energies, a lighter molecule will move faster than a heavier molecule, as shown in the equation for rms speed rms speed = M where R= 8.314 J/(mol.K) and M is molar mass in kilograms per mole. Note that a joule is the same as a kilogram-meter squared per second squared (kg.m-/s). What is the rms speed of Cl,...
