Each of the insoluble salts below are put into 0 10 M hydrochloric acid solution Do you expect their solubility to be more less or about the same as in a pure water solution lead chloride barium sulfite magnesium hydroxide More soluble than in pure water Similar solubility as in pure water Less soluble than in pure water

To an evacuated vessel with movable piston under external pressure of 1 atm 0 1 mol of He and 1 0 mol of an unknown compound vapour pressure 0 68 atm at 0 C are introduced Considering the ideal gas behaviour the total volume in litre of the gases at 0 C is close to

b Suppose you have two chunks of helium gas one at sea level and one at height z each having the same temperature and volume Assuming that they are in diffusive equilibrium show that the number of molecules in the higher chunk is N 2 N 0 e mgz kT in agreement with the result of Problem 1 16

The Boyle temperature TB is defined as the temperature at which the properties of a rea gas coincide with those of an ideal gas in the low pressure limit The graph that shows the pressure dependence of the compression factor Z for a real gas at TB is A C N 1 0 N 1 0 0 0 Pressure bar 1000 A Pressure bar 1000 B D N 1 0 0 1 0 Pressure bar N N 0 1000 Pressure bar 1000

O and SO is filled in two different containers A and B respectively at same T and P A has circular orifice while B has square orifice of edge length equal to the diameter of the orifice of vessel A then ratio of rate of diffusion of the gases from vessel A to that from vessel B will be A 2 2 B C 2 1 4 D 2
