Show how to solve: The determination of the heat of neutralization for HCl was determined, using a calorimeter having a calorimeter constant of 85.0 J/°C. To this calorimeter, 50.0 mL of 2.100 M HCl were added to 50.0 mL of 2.210 M NaOH. The temperature rose from 25.0 °C to 35.0 °C. The specific heat of the mixture is 5.02 J/g°C. The density of the mixture is 1.02 g.cm-3. What is the heat of neutralization for HCl in kJ/mol? (Answer...

A common laboratory reaction is the neutralization of an acid with a base. When 49.6 mL of 0.500 M HCl at 25.0°C is added to 52.0 mL of 0.500 M NaOH at 25.0°C in a coffee cup calorimeter (with a negligible heat capacity), the temperature of the mixture rises to 28.2°C. What is the heat of reaction per mole of NaCl (in kJ/mol)? Assume the mixture has a specific heat capacity of 4.18 J/(g·K) and that the densities of the...
