Hexavalent Chromium Research Paper

318 Words2 Pages

Chromium is a transitional element, with three stable forms. It is a neutrally charged stable form, but naturally occurs in the environment. Trivalent chromium is a +3 charge stable form of chromium that can be naturally oxidized from its neutrally charged version, occurring in the environment (Mertz et al., 1974; Barrett et al., 1985; Alexander et al., 1990). Hexavalent chromium is a +6 charge stable form of chromium which is the product of industry, and it is very toxic to living things. Hexavalent chromium may be reduced naturally in the environment to the less harmful trivalent chromium. Trivalent chromium is also mostly insoluble, while hexavalent chromium is very soluble allowing for this toxic substance to flow easily as a contaminant

  • Analysis Of Nickel And Dimed By Barbara Ehrenreich

    204 Words  | 1 Pages

    In a capitalist world, there are many opportunities to succeed, but an individual must be willing to work hard in order to ascend the social ladder. In Nickel and Dimed by Barbara Ehrenreich, she undergoes an experiment to see whether or not the average low-wage worker can get by in America. Ehrenreich claims that based on the wages that the low wage worker receives, he/she can not really get by and thus they don’t really have a way to get up out of poverty. However, the working poor do in fact have an opportunities to succeed, such as working up the corporate ladder from the bottom and saving money to build wealth, making Ehrenreich’s argument invalid.

    According to the observations recorded, the metal ion Cesium is present in the “unknown samples”. Unknown sample number five produced a violet color when placed in the flame. Unknown sample number four produced an orange color when placed in the flame. Unknown sample number one produced a violet color when placed in the flame. This evidence supports the claim that the metal ion Cesium is present in the unknown samples according to table two, the Flame Spectra of the Alkali and Alkaline-Earth Elements.

  • Dioxins Research Paper

    2333 Words  | 10 Pages

    Dioxin is a large group of chemical compounds that are persistent environmental pollutants (POPs), which essentially comprise carbon, hydrogen, oxygen and chlorine atoms with similar structure. The toxicity of different dioxins is determined by amount of chlorine atoms and their positions in the dioxin molecule. To that, the most toxic dioxin has four chlorine atoms in positions 2, 3, 7 and 8, namely 2, 3, 7, 8-tetrachlorodibenzo-p-dioxin, which is also usually known as TCDD or generically “dioxin”. The name "dioxins" is often used for the family of structurally and chemically related polychlorinated dibenzo para dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs). Certain dioxin-like polychlorinated biphenyls (PCBs) with similar toxic

  • Tetrachloroethylene Research Paper

    570 Words  | 3 Pages

    Tetrachloroethylene is a clear, nonflammable liquid, and is a commonly used solvent that has been in commercial use since the early 1900s. It can be found in water repellant, paint remover, printing ink, glue, sealant, polish, and can also be used to make other chemicals. Although it has been detected in small amounts in the air and in some sources of drinking water, the most common source of exposure is in the industries that use this chemical. Such industries are the dry-cleaning business, where it is used as a solvent, and businesses that degrease and clean metals, or need to dissolve greases and oils from fabrics. Because Tetrachloroethylene is a chlorinated hydrocarbon, it is a central nervous system depressant, and can easily enter the body through respiratory or dermal exposure, allowing this to be taken into the body dangerously easy.

    Many people do not realize that chemistry is a part of our day to day lives. One specific thing we see on a daily basis is the colors and paint people use in paintings, on buildings, and any other place paint could be. When this paint is developed, the people who make it have to decide exactly what the compound should be made up of. This is an important thing to consider when making these paints because as discussed in Chemistry 101 lab, compounds are different things that develop one item, in this case it is paint. They have to make sure that the paint is homogenous because if it was heterogeneous when being applied, the paint would not go on well.

    “Hydrogen bomb or H-bomb, is a weapon deriving a large portion of its energy from the nuclear fusion of hydrogen isotopes. In an atomic bomb, uranium or plutonium is split into lighter elements that together weigh less than the original atoms, the remainder of the mass appearing as energy. Unlike this fission bomb, the hydrogen bomb functions by the fusion, or joining together, of lighter elements into heavier elements. The end product again weighs less than its components, the difference once more appearing as energy. Because extremely high temperatures are required in order to initiate fusion reactions, the hydrogen bomb is also known as a thermonuclear bomb.”
