When two cotton plugs. one moistened with ammonia and the other with hydrochloric acid, are simultaneously inserted into opposite ends of a glass tube that is 87.0 cm long, a white 1111g of NH4Cl forms where gaseous NH3 and gaseous HC1 first come into contact. NH3(g)+HCl(g)NH4Cl(s) At approximately what distance from the ammonia moistened plug does this occur? (Hint: Calculate the rates of diffusion for both NH3 and HCI, and find out how much faster NH3 diffuses than HCI.)

A weighed quantity of PCI5(s) is sealed in a 100.0-cm³ glass bulb to which a pressure gauge is attached. The bulb is heated to 250°C, and the gauge shows that the pressure in the bulb rises to 0.895 atm. At this temperature, the solid PCI, is all vaporized and also partially dissociated into Cl2(g) and PCI3(g) according to the equation PCI5(g) 2 PCI3(g) + Cl(g) At 250°C, K = 2.15 for this reaction. Assume that the contents of the bulb are at equilibrium and calculate the partial pressure of the three different chemical species in the vessel.

n Unknown elemental metal was reacted with Hydrochloric Acid. It was determined that this reaction evolved Hydrogen gas and left the metal in solution in the 2+ oxidation state. The Unknown metal was then subjected to the same test as Magnesium in the “Molar Mass of Magnesium” lab. After some adjustments to get the volume of gas collected in the right range, the following results were obtained: Mass of Metal used = 0.3682 g P (atmospheric) = 761.1 mm Hg Temperature of gas = 21.6 degrees C Volume of gas collected = 67.5 ml Difference in height of solution levels in the buret and beaker = 163.0mm Vapour pressure of H20 at gas temperature = 19.349 mm Hg Some Constants: R = 0.0820575 L*Atm/mol/K = 62.3637 L*mmHg/mol/K dsolution = 1.00g/ml dHg = 13.6 g/ml From this data, calculate and report the molar mass of the unknown metal with correct significant figures and unit
