University of Nebraska at Omaha Bomb Calorimetry Physical Chemistry 3354 Enthalpy of Combustion: 1‚2-diphenylethane January 6‚ 2014 Author: Jon D. Paul Signature Professor: Dr. Edmund Tisko Date Abstract Experimentation involving constant volume calorimetry produces the heat of reaction for many substances. When choosing adiabatic conditions we are allowed to focus on the reaction system while neglecting everything else. The reactions that are studied should proceed relatively

The Debate There has been a debate over whether ADHD is being overdiagnosed‚ thus overmedicating patients. The rate of ADHD diagnoses has increased immensely. In 1990‚ 900‚000 youths were diagnosed with the disorder; while in 2000‚ three to four million children are diagnosed with the disorder (Mayes‚ 2009). This increased rate can be attributed to many factors. The age range for the diagnosis of ADHD has broadened‚ allowing more children as young as four to be diagnosed with the disorder (Rubin

of nuclear bombs. The two main types of nuclear weapons: atom bombs and hydrogen bombs. The hydrogen bomb is the most powerful‚ destructive bomb of all. In this essay I’m going to give a brief history of the hydrogen bomb‚ the chemistry behind the bomb‚ and how much destruction the hydrogen bomb can do. After the Soviet Union’s atomic bomb success during the cold war‚ the U.S wanted something bigger and stronger. In 1950‚ President Harry S. Truman announced work on the hydrogen bomb. A group of

heat of combustion for naphthalene. This is the some basic bomb procedures. In this experiment‚ we us naphthalene as a fuel in bomb calorimeter which naphthalene powder is turned to pellet using pellet press. The fuel is burnt at constant volume condition in a high pressure container (the bomb). The whole bomb‚ pressurized with excess of oxygen. The mass of iron wire‚ ma =0.02g. The mass of naphthalene pellet with iron wire‚ mb =0.38g. The bomb is submerged in 850g of water and the initial temperature

The Manhattan Project World War II started on September 1 1939‚ when Germany attacked Poland. By 1941‚ the Germans were ahead in the race for the atomic bomb. They had a heavy-water plant‚ high-grade uranium compounds‚ capable scientists and engineers‚ and the greatest chemical engineering industry in the world. Even before its entry into the war‚ the United States had become very concerned with the nuclear threat of the Axis powers. On October 11‚ 1939‚ President Franklin D. Roosevelt received

The First Presidential Debate At the first debate where estimated 100 million people watching‚ Donald Trump and Hillary Clinton shook hands with smile on the stage‚ and Lester Holt of NBC nightly news explained the rule of the debate. It was a temperament test for Trump to prove that he is suitable for the President. However‚ he failed to do so in my opinion. This debate proves that he is not sincere‚ not patient enough to listen‚ not honest‚ not prepared enough‚ and absolutely not suitable for
