Question
Chapter 19, Problem 78AE
Interpretation Introduction
Interpretation: A reaction taking place in particle accelerators is given. The energy change for the reaction is to be calculated. Whether the energy is released or absorbed and the possible source for this energy is to be identified.
Concept introduction: In a nuclear fission, two light nuclei combined to form heavier nuclei. In a nuclear reactor, a self-sustained fission chain reaction occurs and energy is released during the process.
To determine: The change in energy for the given reaction; whether the energy is released or absorbed and the source of energy.

When 15.00 mL of 3.00 M NaOH was mixed in a calorimeter with 12.80 mL of 3.00 M HCl, both initially at room temperature (22.00 C), the temperature increased to 29.30 C. The resultant salt solution had a mass of 27.80 g and a specific heat capacity of 3.74 J/Kg. What is heat capacity of the calorimeter (in J/C)? Note: The molar enthalpy of neutralization per mole of HCl is -55.84 kJ/mol.
