1.
The combustion of 0.1584 grams of
benzoic acid increases the temperature of a calorimeter by 2.54 °C. Calculate the heat capacity of this
calorimeter. The energy released by the
combustion of benzoic acid is 26.42 kJ/gram.
2. In a coffee cup calorimeter,
100.0 mL of 1.00 M NaOH and 100.0 mL of 1.00 M HCl are mixed. Both solutions were originally at 24.6 °C. After the reaction, the final temperature is
31.3 °C. Given that the density of 1.00
M NaCl is 1.038 g/mL and the specific heat of 1.00 M NaCl is 3.87 J/g°C, calculate the DHneut/mole
for the reaction of HCl with NaOH.
Assume that no heat is lost to the surroundings.
