Calculate the enthalpy of change, Delta H of rxn, for each of the reactions. record the values in the data table part 2
I calculated the heat of rxn of the HCl +NaOH------NaCl + H2O. How do i go from here to enthalpy of change
You have q. Then delta H = q/grams or q/moles depending upon the units you want for the answer.
Dr.Bob222, so, i had to use 50 mL of HCL and NaOH. (2M), so i would do Qrxn/0.1 mol
Yes, that will give you delta H in J/mol or cal/mol. Most of the time these are expressed as kJ/mol or Kcal/mol.
