1) When hydrogen and oxygen gas combine, water vapor is often the product. If 2.98 L of hydrogen gas at 1.05 atm and 25 degress C combine with the 2.05 L of oxygen gas at 821 mm Hg and 20 degrees C, how many mL of water vapor at STP, could result?
2) 150 g of ice at -12 degress C are added to 250 g of water at 35 degrees C. At equilibrium how many grams of ice if any will remain?
3) A glass containing 345 mL of a carbonated soft drink was left sitting out on a kitchen counter. If the CO2 released at room temp (25 C) and pressure (1 atm) occupies 1.4 L, what is the concentration, in ppm, of the CO2 in the original soft drink? (denisty of original drink .965 g/mL)
4) How would you prepare a 6 molar HNO3 solution if only 3 molar and 12 molar solutions of the acid are available for mixing?
5) Consider the reaction of 0.5 molar aqueous solutions of barium chloride and sodium sulfate reacting to form 1.5 molar sodium chloride and barium sulfate precipitate. What is the equilibrium constant of this reaction? At equilibrium, is the concentration of the products greater that that of the reactants? If the concentration of barium chloride were doubled, which direction would the equilibrium shift?
