Carla and her friends were tasked with determining the heat of reaction for the neutralization of the newly synthesized monoprotic acid HX and NaOH. The rubber ball calorimeter was initially calibrated using the reaction of 7.0 mL of 0.200 M HCl and 14.0 mL of 0.1000 M KOH. This measured a temperature rise from 15.7 °C to 27.9 °C. After that, the heat of reaction was calculated for a combination of 2.00 mL of 1.00 M NaOH and 5.0 mL of 1.00 M HX. This represented a temperature rise of 3.7 degrees Celsius. What is the calorimeter's heat capacity in J/°C? (Δ??????????????? =-55.85 kJ/mol)? For the reaction between NaOH and HX, create the chemical and net ionic equations that are equally balanced.
