Question 2
Which of the following reactions needs to be reversed to solve for the Heat of Neutralization between Hydrochloric Acid and Ammonia?
Question 3
What is the molar heat of neutralization (Enthalpy of Reaction) in kJ/mol if 5 moles of HA neutralized 5 moles of BOH and released 8173 J of heat?
Question 4
Calculate the molar heat of neutralization in kJ/mol of the reaction between HA and BOH given the following information:
