The following information was obtained when carrying out an experiment to determine the Enthalpy of neutralization (ΔH) reaction between HCl and NaOH. 100 mL of 2.00 M HCl solution was added to 95.00 mL of 2.00 M solution of NaOH. The final temperature reached was 35.40 °C and the initial temperature at mixing was 22.15 °C. The density of the reaction mixture was 1.04 g/mL and the specific heat capacity was 3.89 J/g-°C. What is the enthalpy of neutralization reaction...

ml HCL solution was added to 51 ml NaOH
1. Would the following errors result in a higher or lower heat of neutralization? a. Student transferred 40,0 mL of HCI instead of 50.0 mL H b. Student used the temperature at 15 min. as final temperature instead of using the graph. Student used the specific heat of water, 4.184 J/g°C instead of the specific heat of C. the NaCl solution, 3.98 J/g°C. If the theoretical heat of neutralization for...

2. A 49.45 mL volume of 1.00 M HCl was mixed with 49.14 mL of 2.00 M NaOH in a coffee cup calorimeter (with calorimeter constant = 25.1 J/°C) at 21.34 °C. The final temperature of the aqueous solution after the reaction was 29.37 °C. Assuming that them heat capacity of the solution is 4.18 J/g/°C, calculate the following: e. The enthalpy change (∆H) for the neutralization in kJ/mol HCl ( this should be a negative number) e. The enthalpy...
