1) Convert 6.66 calories to joules.
2) Will a weak acid/strong base neutralization have the same molar heat of neutralization as the strong acid/strong base neutralization? Explain.
3) In a calorimetry experiment, why would one use the heat capacity of a 2.5 M NaCl solution (3.59 J/gC) rather than the heat capacities of the original acid and base solutions?
4) Why is the dissolving of ammonium chloride endothermic? Would you get similar results for dissolving all salts? Explain your answer using another salt as an example.
5) In a calorimetry experiment, suppose the calorimeter used in the experiment had been made of a heat-conducting material such as a metal rather than styrofoam. Would the measured calorimeter constant be larger or smaller? Explain.
