Heat of Neutralization Introduction: Enthalpy is, by definition, a thermodynamic quantity equivalent to the total heat content of a system. The heat released from a reaction is caused by the change in enthalpy when matter is change by the occurrence of a chemical reaction. In this experiment, the purpose was to demonstrate the calorimeter’s heat capacity through the use of chemicals and water. This produced an exothermic reaction; a reaction producing heat. Experimental: At the beginning of the experiment, a thermos, magnetic stir bar, and a thermometer were gathered. The mass of each object was recorded. Water was added to the thermos that was placed on the stir bar. As the water was stirred, the temperature was recorded at equilibrium. Next, more water was added at a set amount and the mass of this was recorded. This mass of the thermos without water was subtracted from the mass of the thermos with water. This mass number gives the exact number for q. Once equilibrium was reached, another set amount of water was measured. After the water reached a temperature of roughly 65 degrees, it was added to thermos. The starting temperature was recorded

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
