Calculate the molar Gibbs free energy (in kJ) of mixing 5moles of He(g) with 10moles of H2(g). The separate gases and the gas mixture are all at a pressure of 1 bar and at a temperature of 36oC. Assume that both the separate gases and the mixture behave ideally.

A spherical balloon contains 10m^3 of helium at 1 atmosphere and 0C. What will be the diameter of the balloon at the altitute of 3.2 kilometer, where the temperature are -7C and 85000 N/m^2 respectively? What would be the diameter of the balloon if instead of the helium we had hydrogen? Find the weight difference for both cases.

If a can containing one pound of freon (CCL2F2) were punctured releasing all the contents as a cloud of vapor, what would be the volume of the resulting cloud? V = _________ cubic meters. What would be density of the cloud? Would it float or sink in the air? ________________g/L; _______________.

A 10 mg of methyl chloride vapor is added to one liter of nitrogen at 20 C. Pressure is kept constant at 1 atmosphere. What is the final volume and the methyl chloride concentration in mg/cu m and ppmv? ______ Liters; _________mg/m^3 ___________ppmv

A water treatment plant uses liquid Cl2 for disinfection, which it obtains in railroad cars containing 55 metric tons. If a catastrophic accident released the entire cargo which completely vaporized, what would be the volume of the resulting cloud? Assume ambient temperature and pressure. What would be the density of the cloud, and would it rise in the air or hug the ground?
