When you calculate ΔH using bond dissociation energies, you often get a slightly different answer than if you experimentally determine ΔH from a calorimetry experiment (See chapter 5). Why do you think this is so? Give an example of a reaction where you think that gas phase bond energy calculations might not be as accurate as a calorimetry experiment done in aqueous solution.

100 grams of molten lead (600°c) is used to make musket balls. if the lead shot is allowed to cool to room temperature (21°c), what is the change in entropy (in j/k) of the lead? (for the specific heat of molten and solid lead use 1.29 j/g⋅°c; the latent heat of fusion and the melting point of lead are 2.45 × 104 j/kg and 327°c, respectively.)
