beneath. This black crust is primarily composed of gypsum‚ a mineral that forms from the reaction between calcite‚ water‚ and sulfuric acid. Gypsum is soluble in water; although it can form anywhere on carbonate stone surfaces that are exposed to sulfur dioxide gas (SO2)‚ it is usually washed away. It remains only on protected surfaces that are not directly washed by the rain. Gypsum is white‚ but the crystals form networks that trap particles of dirt and pollutants‚ so the crust looks black.

The global market for rare earth elements is expected to reach USD 10.96 billion by 2020‚ according to a new study by Grand View Research‚ Inc. Growing demand for metal catalysts such as Cerium and Lanthanum is expected to drive the market over the next six years. These metal catalysts find applications across a host of industries including automobiles‚ metallurgy‚ phosphors and glass among others. In addition‚ growing market for permanent magnets is expected to particularly boost the demand for

P IntroductionThere has been a spill of concentrated sulphuric acid at the chemical plant where I work at as the Safety Engineer. In this report‚ I will explain what Sulfuric Acid is‚ the health risks and hazards associated with it‚ the safety precautions that should be taken and how the spill should be handled. Sulfuric Acid‚ H2SO4‚ also commonly known as battery acid or vitriol‚ is one of the top products in the chemical industry‚ with 40 million tons produced annually in the U.S. It is a colourless

this paper I will be talking about Acid rain in this atmospheric and the issues behind it. “Acid rain is also called acid precipitation or even acid deposition is precipitation possessing a pH of 5.2 or below primarily produced from the emission of sulfur dioxide (SO2) and nitrogen oxides (NOx; the combination of NO and NO2) from human activities mostly the combustion of fossil Fuels”(Butler and Likens‚ 2012) I will also comparing and contrasting the indoor air pollution tobacco smoke with acid rain

analyzed through their melting point and IR spectroscopy to determine whether the metal bonded to a Sulfur atom or an Oxygen atom of the DMSO. After analyzing the IR spectrum‚ it was determined that S=O shifted to a lower wavenumber in CuCl2~2DMSO and that S=O shifted to a higher wavenumber in RuCl2~4DMSO. Introduction Depending on the metal‚ it will bond to DMSO through its oxygen or sulfur atom. This will cause the frequency of the S=O bond absorption to move depending on which atom it bonds

The roots are damaged by acidic rainfall‚ causing the growth of the plant to be stunted‚ or even in its The acid rain causes harmful elements like mercury and aluminum to be leached from the soil and rocks and it is then carried into the lakes where aquatic life may be affected . The effects of acid rain also inhibit plant germination and reproduction. As the pH reaches 5.5‚ plankton‚

paramagnetism. 2 An interhalogen compound is a molecule whose atom contains two or more different halogen atoms (fluorine‚ chlorine‚ bromine‚ iodine or astatine). Most interhalogen compounds known are binary (composed of only two distinct elements). Their formulas are generally XYn‚ where n = 1‚ 3‚ 5 or 7‚ and X is the less electronegative of the two halogens. They are all prone to hydrolysis‚ and ionise to give rise to polyhalogen ions. No interhalogen compounds containing three or more
