1. 1020 atoms of helium at 60 C are mixed with 1020 atoms of argon at 30 C. What is the temperature of the mixture? 2. What is the total momentum of the molecules in a gram of helium gas in a container at a temperature of 300 K?
Which of the following is NOT true about helium gas and argon gas samples at the...
Which of the following is NOT true about helium gas and argon gas samples at the same temperature and pressure? Question 1 options: If you have twice as many moles of argon as helium, the volume of argon will be twice as large. The same number of moles of each will occupy the same volume. One mole each of helium and argon in a container will take up twice the volume of 1 mole of helium by itself. The same...

A gas mixture containing 50 g of Helium (He), 120 g of Argon (Ar), and 0.1 g Carbon monoxide (CO), has a total pressure of 2560 mbar. (M Ar = 39.95 g/mol, M He = 4 g/mol, M CO = 28 g/mol) The gas mixture is used to reduce hematite (Fe2O3, M = 159.6 g/mol) to iron. State which of the gas constituents is expected to react with hematite, derive a chemical equation for this reaction, and determine the mol fraction of gas mixture required for...

Consider a mixture of 2.00 g of helium and 10.0 g of xenon atoms in a container with a volume of 1 L. Assume that helium and xenon are ideal gases. (a) If the root mean square speed (vrms or urms in Chapter 9) of helium is 1500 m/s, what is the temperature of the gas? (b) Assuming that the helium and xenon are at the same temperature, what is the root mean squared speed of the xenon gas? (c)...
