Chemical Weapons Chemical weapons use the toxic properties of chemical substances rather than their explosive properties to produce physical or physiological effects on an enemy. Although instances of what might be styled as chemical weapons date to antiquity‚ much of the lore of chemical weapons as viewed today has its origins in World War I. During that conflict "gas" (actually an aerosol or vapor) was used effectively on numerous occasions by both sides to alter the outcome of battles. A significant

Forces on Physical Properties By Hannah Kloss Chemistry 112L- 01 --- Eric Boakye November 10‚ 2014 Physical properties are properties that can be measured and seen in an object. An example of a physical property of an object would be the color‚ mass‚ solubility‚ volume‚ or the polarity of an object. A physical property can change the appearance of an object‚ but that does not mean that the chemical composition has to change. The chemical composition can remain the same. Physical properties

Chemical Bonds Chemical Bond: is the force that holds atoms together in a compound. They form because they lower the potential energy of the charged particles that compose atoms. Chemical bonds can be broadly classified into two types: Ionic and Covalent. Ionic: metal & nonmetal Metals have a tendency to lose electrons and nonmetals have a tendency to gain them. The metal atom becomes a cation and a nonmetal becomes an anion. The oppositely charged ions attract one another and form an ionic

HARPER CHEMICAL COMPANY The Harper Chemical Company (HCC) was a medium sized producer of industrial chemicals‚ which sold its products primarily to customers in the paper industries and the paint industries. In 1980‚ HCC diversified into the production of a mineral called Dominite. By acquiring the Dominite activities‚ HCC hoped it would yield at least 15% return on investment after taxes. In early 1980‚ the HCC board of directors authorised the construction of a processing plant having a 40 000
