Benzene is a starting material in the synthesis of nylon fibers and polystyrene (styrofoam).

Its specific heat capacity is 1.74 J/(g•K). If 16.7 kJ of energy is absorbed by a 280. g sample

of benzene at 23.0°C, what is its final temperature?

A common lab experiment is known as an acid-base neutralization. Typically, one may perform the following experiment: 50.0 mL of 0.500 M HBr at 25.0°C is added to 50.0 mL of 0.500 M KOH at 25.0°C in a coffee cup calorimeter; and observe the temperature of the mixture rises to 28.2°C. What is the heat of reaction per mole of acid? Assume the mixture has a specific heat capacity of 4.18 J/(g•K) and the densities of the reactant solutions are both 1.00 g/mL.
