1. The normal boiling point for acetone is 56.6 degrees Celsius. At an elevation of 5300 ft the atmospheric pressure is 630 torr. What would be the boiling point of acetone (enthalpy of vaporization=32.0 kj/mol) at this elevation? What would be the vapor pressure of acetone at 25.0 degrees Celsius at this elevation? Using Clausius-Clapeyron equation.
2. Consider a 75.0 gram sample of H2O(g) at 125 degrees Celsius. What phase or phases are present when 215 KJ of energy is removed from this sample?
3. A 0.250 gram chunk of sodium metal is cautiously dropped into a mixture of 50.0 grams of water and 50.0 grams of ice, both at 0 degrees Celsius. The reaction is 2Na(s)+2H2O(l) yields 2NaOH(aq)+H2(g) enthalpy=-368 KJ.
Will the ice melt? Assuming the final mixture has a specific heat capacity of 4.18 J/g*degrees celsius, calculate the final temperature. The enthalpy of fusion for ice is 6.02 KJ/mol.
