Rank the samples of gas described in the table below in order of increasing average speed of the atoms or molecules in them. That is, select "1" next to the sample in which the atoms or molecules have the slowest average speed. Select "2" next to the sample in which the atoms or molecules have the next slowest average speed, and so on. gas sample 2.7 mol of helium gas at 3.0 atm and -21. °C 1.4 mol of argon gas at 2.5 atm and -21. °C 1.5 mol of neon gas at 2.9 atm and -21. °C 1.1 mol of helium gas at 2.1 atm and 3. °C average speed of atoms or molecules X Ⓒ

Since the volume of one mole of any gas at STP is 22.7 L, the density of one mole of any gas at STP is a constant value.  Do you agree or disagree with this statement? Why?

Match the characteristic of gases described below to the postulates of the kinetic molecular theory that best explain that characteristic. (Note: You may need to list more than one postulate.) The pressure of a gas in a fixed volume increases when its temperature increases. Select one or more: The average kinetic energies of gas particles increase with an increase in temperature. Gas particles are widely spaced. A gas consists of many small particles in rapid, random motion. The total volume of the molecules themselves is very small compared to the volume of the container. There are virtually no attractive forces between gas particles.

The average molecular speed in a sample of O2 gas at a certain temperature is 447 m/s. The average molecular speed in a sample of CH4 gas is ____m/s at the same temperature.

Super fast!!!!!

He has a velocity of 1,361 m/s. What is the velocity of Cl2 gas? Assume standard temperature. Nitrogen has a velocity of 515 m/s. What would be the molar mass of a gas with velocity of 194 m/s? Assume standard temperature.

For the following set of pressure/volume data, calculate the new volume of the gas sample after the pressure change is made. Assume that the temperature and the amount of gas remain constant. V = 115 mL at 738 mm Hg %3D V = ? mL at 781 mm Hg Volume mL %3D
