  • Magnesium Oxide Lab Report

    The burning of magnesium in open air causes a chemical reaction that forms the compound, magnesium oxide. This reaction occurs due to the heat that provides energy to activate the reaction. A blinding white flame will burn as the reaction occurs. In this lab, magnesium is burned in an open crucible over a Bunsen burner several times until the magnesium ceases to burn. This process allows for the magnesium to completely react with the oxygen found in the open air, forming the chemical compound magnesium oxide. However, our lab did not provide us with the hypothesized results, as no reaction occurred when the magnesium was burned, potentially due to an error in the process. The purpose of this lab is to identify and examine the oxidation-reduction…

  • Explain The Empirical Formula Of Magnesium Oxide

    Abstract: In this lab our main objective is to find the empirical formula of MgO, magnesium oxide. To do this first we have to make sure when we burn Mg in the crucible and it reacts to with O. This lab experiment Mg is complicated by another factor. Mg is so reactive that it reacts with N in the air so some of the Mg which is suppose to react with O will react will N instead. This obstacle can be overcome by simply adding water to the Mg3N2 to yield MgOH2 and NH3. This will undo the reaction so…

  • Summary On Zinc Oxide Nanoparticles With Defects

    Abstract: This paper provides a brief summary of existing article Zinc Oxide Nanoparticles with Defects by Vladislav Ischenko,Sebastian Polarz,Dirk Grote,Victorina Sravarache,Karin Fink,and Matthias Driess. This paper discusses the importance of a nanoscale ZnO with defects in its structure. The article also provides a broad analysis of ZnO nanoparticles using a consolidation of techniques and the resulting data is summarised in this review. The paper gives the realization of when a…

  • Taking A Look At Acid Rain

    1.1 Introduction/ what is Acid Rain? Acid rain, or acid precipitation is a term used to describe any form of precipitation with a pH of less than 5.6. In recent years, the effects of acid rain are being experienced on a global scale with widespread environmental effects. Primarily, acid rain is caused by emissions of sulfur dioxide (SO2) and nitrogen oxides (NOx) from the combustion of fossil fuels. However, even pure rainwater is slightly acidic (pH of 5.6-6.5) due to the reaction between H2O…

  • Soil Characterisation Essay

    that they had distinct soil parameters in terms of total organic carbon (TOC), Fe oxide, Al oxide, pH which have been observed as important controllers for bioaccessibility of As, Cd and Pb reported in previous chapters. MGA soils contained a high amount of TOC (8.37 %), Fe oxide (12.49 g kg-1), Al oxide (12.6 g kg-1) whilst few TOC (1.48 %), Fe oxide (0.64 g kg-1) and…

  • Raman Spectra Analysis

    demands of the continuous casting. In order to coordinate the properties of mold flux, many oxides are used in the mold flux – especially the similar oxides such as Na2O and Li2O, and MgO and CaO. This can micro – adjust the properties of mold flux. The distributions of silicate anionic species (Qn) were obviously different whereas the equimolar substitution of CaO for MgO (and Na2O for Li2O) are at a fixed NBO/T. The degree of polymerization of molten slag with a same NBO/T is same except the…

  • Importance Of Optical Constants

    title>INTRODUCTION Optical constants (complex refractive index n, complex dielectric function ϵ, and reflection and absorption coefficients R and α) of materials are of great importance for optical metrology in the semiconductor industry.1,2 A high-performance complementary-metal-oxide-semiconductor process flow with 11 layers of metal requires about 75 photolayers and may contain up to 100 thickness measurements, most of them performed using spectroscopic ellipsometry.3 This technique has…

  • Hypo Sludge Case Study

    3.1.4 HypoSludge The production of Hypo sludge is estimated about 35% of the daily production in the paper industries. These wastes are used as an ingredient of cement manufacturing in wet process. But present days we use dry process for manufacturing of cement so hypo sludge are not useful for manufacturing of cement. The paper industries are dumped these waste nearby any pit or waste land. It leads to effects the environmental issues. Regarding these situations hypo sludge are…

  • Major Effects Of Air Pollution

    (SO2) and nitrogen oxides (NOx) gases. The combustion of high sulphur content fossil fuels can release harmful toxic gases into the air and therefore pose serious environmental problems. Coal, oil and natural gas are major energy resources available in environment where as fuel combustion processes and power plants are the largest contributor of these gases in the form of flue gas. Since coal and petroleum often contain sulphur compounds, their combustion generates SO2 unless the sulphur…

  • American Air Pollution

    This is what people refer to when they talk about smog. According to the Webster dictionary, smog is “a photochemical haze caused by the action of solar ultraviolet radiation on atmosphere polluted with hydrocarbons and oxides of nitrogen especially from automobile exhaust” (Dictionary, 2016). Because of our atmospheric pollution, when smog is present and it begins to rain, the rain traps the chemicals and brings them down to the earth’s water…
