Magnesium oxide

affect the chemical structure of the magnesium in the fire extinguishing process. However, a protective coat of magnesium oxide is formed on all the surface of the magnesium as it reacts very fast with air. This layer makes it hard for it continue burning. However, in case water is used when removing the residues even after several days, the fire may reignite. The water will firstly expose the surface of the magnesium residues to reaction and react with it (magnesium) to release flammable…

Introduction The purpose of this lab is to find the emperical formula of a compound made of magnesium and oxygen. We took a strip of magnesium and combusted it to figure out how much of the strip was magnesium by weighing the remaining ashes. The weight that wasn’t transferred to ashes was burnt off in the smoke as oxygen. To find the emperical formula, you had to take the average mass of both magnesium and oxygen and divide by the average mass to get the amount of mols in the compound.…

Regarding these situations hypo sludge are used as a partial replacement of cement to increases the durability, setting time and strength of the concrete. In hypo sludge the chemical components present like Silicon Dioxide (SiO2), Calcium Oxide (CaO), Magnesium Oxide (MgO), etc...These are helps to increases the physical and chemical properties of concrete. Fig 3.2 Hypo Sludge Physical properties of Hypo Sludge Hypo sludge waste material is soft. From paper industries we get hypo sludge in wet…

1. Introduction Pre-industrial revolution, humans beings used to live a primitive life whereby they used wood for cooking, warming house; as biofuel. Even later when they lived in houses, they used candles to light up their homes. Post-industrial revolution, human beings discovered new energy resources which have made life much easier to live. And the discovery of these resources (coal and oil), have also supported the advancement of new technologies e.g. automobiles, airplanes, generation of…

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…

Carbon Dioxide, is a natural occurring chemical compound that consists of one carbon atom and two oxygen atoms. On Earth carbon dioxide is released into the atmosphere from respiration, combustion of coal or hydrocarbons, and respiration. However most of the carbon dioxide that is released into the atmosphere is removed by organisms that conduct photosynthesis. Photosynthesis is the processes in which organisms, such as, plants, algae and cyanobacteria (bacteria that obtain their energy from…

As of September 2016, over 260 million Americans have consumed at least 1 bag of potato chips. This means that at least 24375 tons of chips have been eaten in the past year. However, that calculation would only be true if each bag contained at minimum its labeled amount. When opening a bag of chips, it is easy to assume that the labeled amount is false due to the amount of empty space inside. Thus, the goal of this paper is to explore this idea and document the experimentation that follows in…

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 been described in various books…

The change in enthalpy for the combustion of magnesium metal Abstract ======== Hess’s law of heat summation states that the value of DH for a reaction is the same whether it occurs directly or as a series of…

Recent research shows that AgNPs enhance luminol fluorescence and chemiluminescence by acting as a catalyst with hydrogen peroxide. When AgNPs interact with hydrogen peroxide they cause the peroxide to degrade into superoxide and hydroxyl radical, which also react with luminol to form 3-aminophthalate (Equations 2-5) [13]. The further degradation of hydrogen peroxide into other reactive oxygen species promotes higher fluorescence intensity. Figure 5 shows the increased fluorescence intensity…
