The enthalpy of combustion for octane (C8H18(l)), a key component of gasoline, is –5074 kJ/mol. The reaction equation is: C8H18(l) + 12.5O2(g) ( RIGHT ARROW) 8CO2(g) + 9H2O(g).
What is the (TRIANGLE)Hf for this reaction?
16CO2(g) + 18H2O(g) (RIGHT ARROW) 2C8H18(l) + 25O2(g)

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.)
