Nuclear Disasters and Accidents Introduction: One of the scariest things about nuclear power is when something goes wrong and an accident occurs. Radiation is released into the environment and people get hurt. Two of the most famous nuclear accidents occurred at the Three Mile Island reactor 2 in the United States and the Chernobyl reactor 4 in the former Soviet Union. In this text we will discuss these two disasters‚ along with correcting a few common misconceptions about nuclear accidents. The

The Element: Chlorine General Information We researched the chemical element known as chlorine. Chlorine has an atomic number of 17 and an atomic weight of 35.453. It has a valence number of 3. The element has 3 energy levels. Chlorine exists as a greenish-yellow gas at normal temperatures and pressures. Chlorine is second in reactivity only to fluorine among the halogen elements. Chlorine is a nonmetal. It is estimated that 0.045% of the earth’s crust and 1.9% of sea water are chlorine.

Ken Kesey’s use of symbolism in One Flew Over the Cuckoo’s Nest transforms the novel and the hospital within the novel a microcosm of society‚ a battle between the sane and insane‚ the conformist and the non-conformist. Randle McMurphy’s arrival influenced the lives of almost every person‚ whether patient or employee. Whether or not his motives and actions were moral or good-hearted is difficult to conclude‚ however. On one hand‚ he undoubtedly saved the patients from losing their souls‚ so to

chemical compounds whose molecules contain carbon. For historical reasons discussed below‚ a few types of carbon-containing compounds such as carbonates‚ simple oxides of carbon and cyanides‚ as well as the allotropes of carbon such as diamond and graphite‚ are considered inorganic. The distinction between "organic" and "inorganic" carbon compounds‚ while "useful in organizing the vast subject of chemistry... is somewhat arbitrary".[1] Organic chemistry is the science concerned with all aspects

Chemistry Summary The particle theory: 1. Matter is made of tiny particles 2. Particles of matter are in constant motion 3. Particles of matter are held together by very strong electric forces 4. There are empty spaces between the particles of matter that are very large compared to the particles themselves. 5. Each substance has unique particles that are different from the particles of other substances 6. Temperature affects the speed of the particles. The
