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...

When a chemist mixed 3.33 g of LiOH and 255 mL of 0.62 M HCl in a constant-pressure calorimeter, the final temperature of the mixture was 23.4°C. Both the HCl and LiOH had the same initial temperature, 20.4°C. The equation for this neutralization reaction is: LiOH(s) + HCl(aq) → LiCl(aq) + H2O(l). Given that the density of each solution is 1.00 g/mL and the specific heat of the final solution is 4.1801 J/g·K, calculate the enthalpy change for this reaction...
