Abundance of the chemical elements

As an essential factor to sustain life and the ultimate protector within numerous industries, the element zinc exists as a crucial factor within the world’s scientific realm. This bluish-white, lustrous metal was previously used in various industrial alloys and for medicinal purposes as early as 2,500 years ago by the Romans and Palestinians (“Zinc,” 2016). Greater rates of zinc production then began in India during the 13th century by heating mineral calamine with wool, yet no reference to it…

Trucks bring large amount of water and chemicals. Per frack, “a well site may need up to 2000 tanker truck trips,”(Hoffman 1). Each well as stated before can be fracked up to 20 times. So for each well, 40,000 tanker truck trips are made. This is not only contributing to the waste of oil, it 's…

This was accomplished by precipitating three different solutions (Solution A, B, and C) with silver nitrate to create a compound of silver and the unknown element. Given that 0.01 moles of AgX were present, the grams of silver and the unknown element were calculated. Using the periodic table, the unknown elements were able to be determined. Calculations Given: 0.01 mol AgX 1 mol Ag = 107.868g Solution A: (mol of Ag)(molar mass of Ag) + (mol of A)(unknown) = mass of salt .01 mol…

V. The Cat’s Eye Nebula One of the most famous nebulae is the Cat’s Eye Nebula (NGC-6543); it was discovered by William Herschel in 1786. NGC-6543 is located in the northern constellation of Draco; it appears as a blooming center with surrounding and expanding rings. The NGC-6543 has a historical importance because it was the first nebula to be studied spectroscopically by the astronomer William Huggins in 1864; this study revealed the distinctions between PNe and the other gaseous nebulae.…

Selling and Making Cigarettes? Ethical or Not? In the great nation of the USA everyone has the right to their own choices, and also obtains the right to have a role in our capitalist economy, whether that be a owning a convenient store, having a job in advertising, or creating a company to sell specific products or services. In the first rendition of the, changing forever more, United States economy they had a completely laissez-faire style. This term, of French origin meaning to allow to…

The purpose of this lab is to calculate the chemical formula of a hydrate compound made up of copper, chlorine, and water molecules by using the law of definite proportions. The water of hydration of the copper chloride hydrate sample will be determined as well as the mass of copper and chlorine through a chemical reaction. The results will be used to calculate the moles of copper and chlorine and then the empirical formula of the compound. Techniques used: In this experiment, different…

The element silver (ag) is named from the Anglo-Saxon word seolfor, it’s chemical symbol, Ag, comes from the Latin word argentum, derived from the Greek ὰργὀς (are-ah-gush). This name comes from a Proto-Indo-European language root. Silver has been around for thousands of years, with many versatile uses. From a scientific layout, silver has an atomic weight of 107.8682, contains 47 protons and electrons respectively, and has 61 neurons. This element has a melting point of 1234.93 K (961.78 °C…

still possible. Wilson also spoke about the “reflections from the eyes of the wolf spiders on the prowl… how could so many exist in such numbers.” (Wilson, 238) this description of life and the abundance of it is quite the contrary to Carson 's writing. Carson does not mention the thriving of life or the abundance she only insists that the soil is infertile and it is very hard for plants to…

results are displayed as spectra of relative abundance as a function of the mass-to-charge ratio (Anon., n.d.). The sample can be identified by the mass of fragments and the fragmentation pattern (Anon., n.d.). (Sparkman, 2000) 2.3 Mass Spectrum 2.3.1 Nature Mass spectrum will be presented as a vertical bar graph (Anon., n.d.). Each bar represents an ion having specific mass-to-charge ratio (m/z) and the length of the bar indicates the relative abundance of the ion (Anon., n.d.). Most ions…

it can be used for such as cryogenics, lasers and neon signs. Also because neon is so rare compared to other elements Neon was discovered or isolated in 1898 by two chemist named Ramsay and Travers along with krypton and xenon Neon got its name from the Greek word neos which means new Neon is important for lighting,signs,lasers and refrigeration Neon is the fifth most abundant element in the universe but is very rare on Earth(about 0.0018%) of the earth atmosphere its symbol is Ne its atomic…
