    Magnesium is one of the most important minerals for human health and is required throughout the body; but by far the largest quantities are found in the bones and muscles. Almost all the body's enzymes are dependent to some degree on adequate supplies of magnesium, and these enzymes are essential for several hundred vital metabolic reactions; amongst the most important being the production of energy within cells through the metabolism of dietary proteins, carbohydrates and fats. Magnesium is also needed for the synthesis of protein, the activation of genes and the transmission of impulses between nerve cells. In addition to the above general functions, magnesium is a vital element in the complex of nutrients required for the production of glutathione, one of the body's most important fat-soluble anti-oxidant enzymes. Glutathione protects those parts of the body's cells which are composed of fat, such…

    elements form the mass of the earth’s crust, ocean and atmosphere. Two of the most abundant elements of the eight are calcium and magnesium. Calcium and magnesium are located on the periodic table located both in group 2 sharing the same family meaning that they share chemical property’s as well as the same valence electron because of their location and family relation to the period table. The alkaline metals are a reactive group of metals and combine with other elements so easily that they are…

    Aim: • To investigate the effects of on the rate of reaction of magnesium with different concentrations of Hydrochloric acid (HCl). • To investigate the effects of different surface areas of magnesium in its rate of reaction with hydrochloric acid (HCl). Introduction: The rate in which reactions occur between chemicals, such as Magnesium and Hydrochloric Acid, are effected by four main factors. These factors are temperature, concentration, the presence of a catalyst and the surface area of…

    Magnesium Oxide Lab Report

    • 5 Pages

    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…

    If heating magnesium in the presence of oxygen and they react completely, then the ionic compound’s empirical formula can be found using this equation by calculating the masses of magnesium and oxygen in this equation: Mg + O2 → MgxOy Since an ionic compound is the hopeful result of this lab, an ionic compound is a chemical compound comprising ions, which ions are an atom or molecule with a net electric charge due to the loss or gain of an electron. Ions can be negatively charged and called…

    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…

    This lab was a two week long lab called the Grignard Reaction lab. The purpose of this lab was to perform the Grignard reaction and to obtain the final product triphenylmethanol from a halide, phenylmagnesium bromide and the starting material, methyl benzoate along with the Grignard reagent. Bromobenzene, magnesium turnings, and anhydrous ether were needed to form the Grignard reagent. To synthesize the reagent, react the reagent with methyl benzoate to form a tertiary alcohol. The objective of…

    manipulated to find the volume and divide that volume by moles of magnesium. Being close to the theoretical value, 22.4L, it verifies that one mole of all gases occupy 22.4L in any container under standard temperature and pressure. This information could be valuable in many ways. For example, it proves Avogadro’s Law which states that at a standard temperature and pressure, one mole of any gas will occupy the same value which is 22.4L. Like a puzzle piece, once discovered, it…

    A. Heating Magnesium: This station consisted of magnesium, a slim, flexible, silver metal and a Bunsen burner. We used crucible tongs to hold the magnesium over the Bunsen burner until it began to ignite. When it first ignited, sparks were seen and the flame emitted a bright, white light. The flame spread across the magnesium and eventually turned it into a white, ashy substance. The combination of fire and magnesium caused a chemical change. This is evident as there were many signs of a…
