6‚ 1945‚ the United States shocked the world by dropping an atomic bomb over the city of Hiroshima‚ Japan. (www.grolier.com) Hiroshima was a major industrial city with an estimated population of almost 400‚000 people. A B-29 bomber was loaded with the Atomic Bomb and left the United States Pacific air base at 2:45 a.m. local time and dropped the bomb at 8:15 a.m. The bomb was detonated one minute after being dropped. The atomic bomb‚ nicknamed "Little Boy"‚ which was dropped on the Hiroshima

Atomic Theory Essay We are first going to talk about Protons‚Neutrons and Electrons. These three elements are a very good example of most things that are in use of gas fumes. It all started when Protons and neutrons where‚ Protons were discovered by Experimenting with discharging tubes. Eventually they found out the rest of the Atoms over time. Which brings me into the word of Orbital. Orbital is a Neutron‚ electron or a proton Going around a single atom with certain amounts of energy levels. Which

had every right to drop the Atomic bomb on Japan and therefore force them to surrender. The Japanese had at that time‚ already lost quite a lot of battles against the US and were forced to retreat back to Japan. Yet‚ the Japanese borders were heavily fortified. Had the Americans attacked Japan‚ they estimated their losses to be about 500 000 men. By dropping the atomic bomb‚ an estimated number of 100 000 people died. So in the end you can see that dropping the atomic bomb has saved quite a lot of

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

Congenital Heart Defects in Children Congenital heart defects in children are frightening conditions that are yet to be understood fully by cardiologists (Mayo Clinic). Ranging from a benign murmur to complete cardiac arrest‚ congenital heart defects are important disorders to be educated about (Fulton). Because of the potential severity of these illnesses‚ one should understand what is thought to cause this‚ forms of it‚ the risk involved‚ precautionary measures‚ and what the prognosis is. By

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

INTRODUCTION: In atomic spectroscopy the samples are vaporized at 2000-8000k. The process of this involves two steps ‚ one is atomization of sample and the other is absorption of light radiation from light source. The atoms in the vapour are measured by absorption or emission at characteristic wave lengths. The main usage of this was to detect one element from another in the complex sample which has taken ie.‚ it has ability to perform multiple element analyses. Absorbance should obey Beer’s law

Explain the multiple impacts endured by the Mexican Americans. After WWI money was being spent three times the rate of tax collection and soon the government began to cut spending in the 1920’s. This then resulted in the Great Depression. The Great Depression was a massive economic
