of this experiment is to determine the enthalpy of combustion of naphthalene by means of a bomb calorimeter. First‚ the bomb calorimeter was standardized using benzoic acid and the average heat capacity of the bomb calorimeter was calculated to be 10.60.3205 kJ/K. From that‚ the These results show that heats of combustions of unknown substances can be determined via bomb calorimetry. Introduction The first law of thermodynamics states that energy is conserved.2 Using that law it can be said that

Atomic War or Peace? Was the dropping of the atomic bomb on Japan justified? Many people believe that it was very justified‚ but was it? Some reasons could have been the attack on Pearl Harbor‚ the destruction of Japans power to make war‚ also what seemed to the only answer to end war. “I wouldn’t hesitate if I had the choice. I’d wipe ‘em out. You’re gonna kill millions of innocent people‚ but at the same time we’ve never fought a war anywhere in the world where they haven’t fought and killed

Determination of the Resonance Stabilization Energy of Benzene Using Bomb Calorimetry Kaitlynn‚ Jesse ‚ Belinda Truman State University Abstract The resonance stabilization energy of benzene is investigated by the combustion of cyclododecatriene. The heat of combustion for cyclododecatriene was determined using bomb calorimetry and used to solve for the stabilization energy of benzene. The bond stabilization energy of benzene is found to be 167.6 ± 388

The Rutherford Model of the Atom 1. In 1911 Rutherford proposed the nuclear model of atomic structure. He suggested that an atom consists of a central nucleus (where most of the mass of the atom is concentrated) having a positive charge‚ surrounded by moving electrons carrying negative charge. Geiger and Marsden carried out an experiment to verify his proposal. The Geiger/Marsden a Particle Scattering Experiment 1. The apparatus is illustrated in the diagram below. | 2. The apparatus

Environment is our surrounding which includes everything from a non-living to a living being. There are two kinds namely the natural environment and Built environment. In actual parlance if one has to describe a natural environment it is one that has natural existence and the built is one that man is responsible for like the dams cities etc. The natural atmosphere is being polluted due to the unnatural factors. While natural causes like volcano’s have its own turn in causing pollution it is the

The first deaf event that I went to was the on a cold Sunday morning with my mother‚ and I met up with my aunt and uncle. We lived in the outskirts of Charlotte and the church was downtown‚ so we got up at 9 o’clock in order to get dressed. My mother drove‚ and I used the GPS to navigate us to uptown Charlotte and ultimately to Charlotte Deaf Mission at First Baptist Church. We went into the church and went up the stairs to the multi-media room. In there was a little break room where they served
