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

the Atomic Mass # differ from the Atomic #? The atomic mass differs from the atomic number by the fact that the atomic mass is composed of the total number of protons and neutrons in the nucleus‚ and the atomic number is the number of protons found in the nucleus‚ and is identical to the charge of the atom. 3) What is an isotope? Give an example (show how it is an isotope). An isotope is a form of the same atom that differs from the original atom in atomic mass

The goal 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

DEVELOPMENT OF THE ATOMIC THEORY Part A: HISTORY * 1869: Mendeleev formulated the Table of the Elements - listing them by their atomic weight and grouping them with similar characteristics. * 1897: JJ Thomson discovered electron and isotopes‚ and invented the mass spectrometer. * 1898: Marie Curie discovered and isolated radium‚ a new element which unprompted disintegrated into other elements. This proved that the atoms of one element at least were not indivisible. * 1911: Ernest
