... water. are very inexpensive. It does not take a very sophisticated industrial base to produce lethal chemicals. This makes it a viable means of warfare for Third World countries. The use of chemical weapons by Iraq and Libya in 1988 reinforces the danger that these weapons will spread (Cass 1996). Not only are these weapons cheap, but they are very effective. Defense Secretary William S. Cohen held up a five-pound bag of sugar on national television last month to show how, with an equivalent amount of anthrax, Iraq could eliminate at least half the population of Washington. The US Law Enforcement Assistance Administration reported in March 1977 that a sin ...
... Before Weight After Mass of Test tube + KClO4 41.5g 39.8g Mass of Test tube 37.5g 37.5 Mass of KClO4 4.0g 2.3g 2. Set up the apparatus shown below. 3. Gently heat the test tube containing the potassium perchlorate. Gas should begin to collect in the collection bottle. Record all observation. 4. Once the reaction is complete, no more gas give off, allow the test tube to cool. While the test tube is cooling test the gas in the collection bottle with glowing splint. Caution: Do not leave the rubber tubing down in the water trough during cooling or you will experience back-up. 5. After the test tube has cooled weigh it on a balance. What is the change in mas ...
... that will carry on through to the next generation. There have been enough sicknesses and fatalities directly related to the use of methyl bromide for the phase out of the pesticide to be considered a worldwide emergency. The producers and users of the substance argue that phasing out the pesticide will cause will be economically disastrous, but clearly their view does not take into account the devastating effect on the ozone layer and the health of humans by the use of this deadly fumigant, the cost to the community far out ways the cost to the users. So what is the alternative? There is no one single alternative for all of the uses of methyl bromide, but th ...
... of life. It is an attribute characterized by sensation and voluntary movement which described the difference between normal waking state of animals and men and their condition when asleep.2 Other descriptions included an analysis of consciousness as a form of relationship or act of the mind toward objects in nature, and a view that consciousness was a continuous field or stream of essentially mental "sense data." The method believed by most early writers in determining consciousness was introspection—looking within one’s own mind to discover the laws of it’s operation. This belief was limited when it was apparent when observationalists could not agree on ...
... up with a theory that most scientist believe it to this day. this is called the theory of evolution. His book was called “The Origin of Specie.” Alfred R. Wallace, came out with a theory that was almost identical to Darwin’s theory. Darwin’s theory was much more developed and better known. For example Darwin pointed out that farmers would take certain qualities from two different plants and mix them together and it would produce the desired plant. He believed this happened in nature also and he called it “the survival of the fittest” or “natural selection.” There are a lot of different creation stories a ...
... but more than 1.5 PPM would cause mottled tooth, so basically a little fluorine would be okay but a lot of fluorine would be bad (Behrman 182). In 1938, with this information, Dr. Gerald Cox of the Mellon Institute began to promote the addition of fluoride to public water systems, claiming that it would reduce tooth decay, however there were two major obstacles in his path, The American Medical Association, and The American Dental Association. Both associations wrote articles in their journals about the dangers of fluoridation of water supplies. The American Dental Association wrote the following in the October 1, 1944 issue: “We do know the use of drinking w ...
... Corona, New Mexico. The next day William "Mac" Brazel, foreman of the Foster Ranch, and his seven-year-old neighbor, Dee, found the remains of the wrecked UFO scattered over a large area. When Brazel drove Dee back home, he showed some of the material to her parents. They all agreed the material was unlike anything they had ever seen. On July 6 Brazel drove into town with a few pieces of the wreck. He showed the material to the Chaves County Sheriff George Wilcox. The sheriff called the Roswell Army Air Field(AAF) and talked to Major Jesse Marcel, the intelligence officer. After inspecting Brazel's material, Marcel reported to his commanding officer Colonel Willia ...
... sometimes exceeding 98% . The chiral manganese complex Jacobsen utilized was [(R,R)-N,N'-Bis(3,5-di-tert-butylsalicylidene)-1,2- cyclohexanediaminato-(2-)]-manganese (III) chloride (Jacobsen's Catalyst). (R,R) Jacobsen's Catalyst Jacobsen's catalyst opens up short pathways to enantiomerically pure pharmacological and industrial products via the synthetically versatile epoxy function . In this paper, a synthesis of Jacobsen's catalyst is performed (Scheme 1). The synthesized catalyst is then reacted with an unfunctional alkene (dihydronaphthalene) to form an epoxide that is highly enantiomerically enriched, as well as an oxidized byproduct. Jacobsen's work ...
... skis, wheelbarrows, and lawn mowers. In 975AD calcium was useful for setting broken bones. There have been many uses for calcium over the years, but calcium has not been available on a large scale until the twentieth century. Calcium is a metallic element, which is fifth in abundance in the Earth’s crust. It is essential for forming leaves, bones, shells, and Portland Cement. Calcium occurs in many highly useful compounds such as marble, limestone, and chalk. Plants and animals must have calcium to live. A plant cannot grow without a good supply of calcium. A lack of calcium prevents bones from developing properly. Calcium is the major component of te ...
... second highest cause of water pollution is ship waste. Ships used to take much garbage with them on their ships and dump them. This was very common until the government took action. They were giving sailors up to one million dollars fines for disposing waste. Because of that, ships now carry less garbage with them. Animals are not the only thing being harmed by water wastes. Fishing lines, rope, and plastic nets are being caught in the rutter and the engine, but the ships are not exactly perfect. The other main cause of water pollution is industrial waste. Industries do not be harmed by water pollution but the cause much it. Many companies pour chemicals i ...
