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 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

The Atomic Bomb: Beneficial or Disastrous? Was dropping the atomic bomb on Hiroshima and Nagasaki at the end of World War II the most affective action that the United States could have taken? In the American eyes it was a good punishment on Japan in response to the Pearl Harbor attacks on December 7‚ 1941. The way the Japanese leaders launched the fighter planes that came in a destroyed many U.S. naval ships and took thousands lives‚ including soldiers and innocent bystanders‚ was a completely immoral

As a citizen from the U.S.A.‚ I believe that we should not drop the bomb in Japan.The use of the bomb without warning is contrary to the position of the United States as a great humanitarian nation‚ especially since Japan seems close to surrender.More than 60 of its cities have been destroyed by conventional bombing‚ the home islands are being blockaded by the American Navy‚ and the Soviet Union entered the war by attacking Japanese troops in Manchuria. Even general Dwight Eisenhower said that the
