Find the wavelength of light that would be emitted when a hydrogen atom undergoes the transition from the state n = 4 to the state n = 2. Express your answer in nm. (hint: the wavelength for the transition 41 is 97.534 nm, 21 is 121.556 nm, and 31is 102.583 nm) TRUE or FALSE: At a given temperature, all gas molecules in a sample have the same velocity. According to the kinetic molecular theory of gases, which of the following gases will have the greatest average molecular speed? HF H2 Ar The pressure in a natural gas tank is maintained at 2.20 atm. On a day when the temperature is 15°c, the volume of the gas in the tank is What is the volume of the same quantity of gas on a day when the temperature is 31°c? Write the noble gas core electron configuration for the following species: Mg Zn2+ A 0.5 mol sample of oxygen is confined at 0oC and 1atm in a cylinder with a movable piston. The piston compresses the gas so that the final volume is half the initial volume and the final pressure is 2.2 atm. What is the final temperature of the gas in degree Celsius? 21.
