Thermochemistry is the study of the heat energy involved in chemical reactions and changes of physical state . Heat energy is always spontaneously transferred from hotter to colder matter. The First Law of Thermodynamics (Law of Energy Conservation) states that the total energy of the universe must remain constant.

Dec 10, 2007 · Write the balanced equation for the reaction of NaOH and HCl. Calculate its enthalpy change (per mole) for this reaction. Heres my data: 25.0 mL of 2.00 M HCl 25.0 mL of 2.00 M NaOH Both temps are 24'C (above) NaOH and HCl added together achieve a high temp of 34'C. *Each solution contains 0.050 moles of NaOH and HCl How do I do this? :( CONCLUSION The purpose of this experiment was to verify Hess’s law associated with three reactions. Our experiment confirmed it by combining the enthalpy changes of two reactions to equal of that another single reaction (Reaction 2 in our case).

Conclusion: The ∆Hrxn of ammonia (NH3) and hydrochloric acid (HCl) to form ammonium chloride (NH4CL) is kJ/mol was -15.6 kJ/mol. The ∆H of the first and second reactions were -23.3kJ/mol and -7.7kJ/mol, respectively. • Laboratory notebook—prepared before lab (if required by your instructor) SafetyNotes. • Eye protection must be worn at all times. • Hydrochloric acid and sodium hydroxide are caustic and should not come in contact with your skin or clothing. Wear gloves when handling these chemicals. A lab coat or lab apron is recommended.
