Provide a thermochemical reaction

Reference no: EM13874264

In one experiment, a student placed 50.0ML of 1.00M HCl at 25.5 degrees C in a coffee-cup calorimeter. To this was added 50.0mL of 1.00M NaOH solution also at 25.5 degrees C. the mixture was stirred, and the temperature quickly increased to a maximum of 32.2 degrees C.

a) provide a thermochemical reaction, including delta H (watch sign)

b) What is the energy (delta H) evolved in kJ per mole of HCl?

Because the solutions are relatively dilute, we can assume their specific heats are close to that of H2O, 4.184 JgC. However, do not assume the density of the solutions is that of water. the density of 1.00M HCl is 1.20g/mL and 1.00M NaOH is 1.40g/mL.
