2. Explain an automobile tire at 32.0 psi at 75.0 degrees F is driven on trip. At the end of the trip the pressure is 35.0 psi. Explain what is the temperature of the tire in degrees Celsius?
3. Compute the height in meters of a column of liquids ethanol (density=0.7893 g/cm3) needed to exert the same pressure as 760mmHg (d=13.60g/cm3)
4. If 250. L of nitrogen reacts with 582L of hydrogen by the reaction: N2 (g) + 3H2 (g) --> 2NH3 (g), explain how much nitrogen is unreacted? All gases are at the same temperature and pressure.
5. A 34.8mL sample of an unknown, water-insoluble gas was collected over water at 22.6 degrees Celsius and a barometric pressure of 0.895 atm. While the gas was dried and chilled, it formed 114.6mg of liquid. Explain what was the molar mass of this substance? Vapor pressure of water at 22.6 degrees Celsius is 20.mmHg
