At a given temperature, 0.300 mole NO, 0.200 mol Cl2 and 0.500 mol ClNO were placed in a 25.0 Liter container. The following equilibrium is established:
2ClNO(g) 2NO(g) + Cl2(g)
At equilibrium, 0.600 mol of ClNO was present. What are the number of moles of Cl2 present at equilibrium? and what is the equilibrium constant, Kc?
The mixture is cooled to the temperature of liquid nitrogen at which ammonia freezes out and the remaining gas is removed from the vessel. Upon warming the vessel to 0.00 degrees C and 1 atm , the volume is 74.0 cm^3 .Calculate the mole fraction o..

You have a sample of bone collected from Nevada and you find that it contains strontium-90 and exhibits an activity of 2.5 Bq. How much strontium-90 was present in the bone when the animal died 45 years ago?(The half-life of 90Sr is 29 years.)
Calculate the work done (in Joules) when 1 mole of ideal gas at 2 bar pressure and 300 K is expanded isothermally to a pressure of 1.5 bar, with the external pressure held constant at 1.5 bar.
O2(g) + 4 HCl(g) → 2 H2O(l) + 2 Cl2(g) When 64.5 g of HCl are allowed to react with 17.6 g of O2, what is the theoretical yield of Cl2(g) in this reaction.
Calcium (Ca+2) and Magnesium (Mg+2) ions are both present in seawater [Ca+2] = 0.011M and Mg+2 = 0.059 M. When aqueous sodium hydroxide (NaOH) is gradually added to the seawater, calcium hydroxide
