50.0 ml each of NaOH (aq) and HCl (aq), both at a concentration of 1.00 M and a temperature of 20.5°C, are mixed in a styrofoam coffee cup calorimeter. The final temperature of the system is 27.3°C. The resulting 0.500 M NaCl (aq) has a density of 1.02 g/ml, and a specific heat of 4.02 J/g-deg. What is the value of ?H in kJ/mole or the reaction?NaOH (aq) + HCl (aq) ? NaCl (aq) + H20 (l)
