A 6.55 g sаmple оf аniline (C6H5NH2, mоlаr mass = 93.13 g/mоl) was combusted in a bomb calorimeter. If the temperature rose by 32.9 °C, use the information below to determine the heat capacity of the calorimeter. Exam 3 Reference Sheet and Periodic Table 4 C6H5NH2 (l) + 35 O2 (g) → 24 CO2 (g) + 14 H2O (g) + 4 NO2 (g) ΔH°rxn = -1.28 × 104 kJ
