are they are used to great effect‚ killing thousands and injuring many more. Chemical weapons were first used in combat in May 1915 when the Germans released chlorine gas against the French in the Battle of Ypres. Over the course of WWI new chemical agents were developed including cyanide‚ phosgene and mustard gas. The Geneva Protocol of 1925 condemned chemical weapons but states that if a state used chemical weapons retaliation in kind was acceptable. The treaty also did nothing to stem the production

In the displacement reaction of metals‚ the more electropositive metal will displace the less electropositive metal from its salt solution Through the observations of experiment results‚ aligning them with theory‚ oxidizing and reducing agents are distinguished. DISCUSSION Part A: Metal-Metal Ion Displacement Reactions In the first set experiments involving metal-metal ion displacement metal-nitrate solutions were prepared first. Using the formula: Molarity=moles of solute liters

Impact of The Vietnam War on Society (Aus&VC) The Vietnam War had a lasting effect on Vietnam Vets‚ Who although fought their hardest for their country returned to a country that saw them as murderers and less than heroes. There were no parades for them and they were met with contempt rather than gratitude. Many of the Vietnam veterans suffered from both psychological and medical problems from open battles‚ sniper attacks‚ chemical warfare and just the general stress of war life. Although the Vietnam

Abstract: The purpose of this experiment was to determine the percentage purity of the iron(II) salt in an unknown sample. We performed titrations using Potassium permanganate which is a strong oxidizing agent‚ with unknown sample dissolved in deionized water. The result of the experiment was a 99.5% purity for the anhydrous iron (II) ammonium sulfate. Introduction: In this experiment‚ oxidation/reduction (or redox) will be used in the titration analysis of an iron compound. We will use potassium

Toxicological Chemistry - relates the aspects of toxicology to the chemical structure and reactivity of the toxin. It is concerned with the chemical interaction of the toxin with the receptor that gives the physiological response. The ultimate aim is to relate functional group chemistry of both toxin and receptor to the interaction Toxicity - the degree to which a substance causes damage to an organism Acute toxicity - the adverse effects resulting from a single exposure‚ or exposure over

to TCDD. Dioxin is formed as an unintentional by-product of many industrial processes involving chlorine such as waste incineration‚ chemical and pesticide manufacturing and pulp and paper bleaching. Dioxin was the primary toxic component of Agent Orange‚ was found at Love Canal in Niagara Falls‚ NY. (http://www.enviroweb.org/issues/dioxin/index.html) The major sources of dioxin are in our diet. Since dioxin is fat-soluble‚ it bioaccumulates up the food chain and it is mainly (97.5%)

compound. This method is based on either acid-base reaction or oxidation-reduction (Redox) reaction. Usually potassium permanganate solution is used as a standard solution in such redox reactions. Since potassium permanganate ion is a strong oxidizing agent ‚ hence can be used to analyse the solutions. The main advantage of permanganate solution in the titration of colorless unknown solutions is that it acts as self-indicating. The color of

robots that walk‚ talk‚ appear human‚ and also make friends with people such as a human would do. We need to examine the meaning of the word artificial intelligence. All textbooks define the field as "the study and design of intelligent agents" where an intelligent agent is a system that perceives its environment and takes actions that maximize its chances of success. John McCarthy‚ who coined the term in 1956‚ defines it as "the science and engineering of making intelligent machines.” Reading these
