  • 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…

  • Determining The Empirical Formula Of Magnesium Oxide

    Title Determining the Empirical Formula of Magnesium Oxide Introduction Chemical formulas imply the arrangement of compounds. Empirical formulas are the simplest whole number ratio of the elements present in a compound (Owen, 2014). However, the actual amount of each type of atom that a compound is consisted of is called the molecular formula. For that reason, the deduction of the empirical formula and the molar mass of a compound is required to determine the molecular formula of the compound.…

  • Analysis Of The Enthalpy Of Formation Of Magnesium Oxide

    In part C, the enthalpy of formation of magnesium oxide was found by adding together three reactions, as shown in the table below. Experiments were performed to obtain the ΔHrxn value of the first two reactions in the table, which were reactions 4 and 5 respectively in the experimental section, while the ΔHrxn for the third reaction in the table was provided. Using the ΔT obtained experimentally, heat energy (q) was determined using the equation q = mCΔT + CΔT where q was the heat, m was the…

  • Decision Tree Analysis In Chemistry

    The powder do not 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…

  • 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…

  • Emperical Formula Lab Report

    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.…

  • How To Save Our Planet Essay

    We have one planet to live on. Have you ever thought of that? We only have this one giant rock, hurtling through the sky at speeds too fast for us to even comprehend; and we have nowhere else to go. Yet, we still take advantage of our home. We pollute it, mine mountains, clear-cut forests and think nothing of it. In everyday life people normally like to keep their home clean and tidy, they may buy insurance to help them buy a new one if something happens to their old one. Earth is our home, yet…
