In the experiment you have added 50.0 mL of Ni(H2O)6
2+ to the calorimeter. To this you
add 5.0 mL of ethlylenediamine and measure the change in temperature of the solution as
the reaction proceeds. The temperature increases by 3.4 oC. Calculate the enthalpy (H)
for this reaction in kJ/mol. [ Answer: -1.0x102 kJ/mol ]
