Magnesium

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 not found on earth in the form of their free metal. They are seen in nature in the form of ionic compounds like calcium carbonated and this occurs naturally in limestone etc. Alkaline earth metals…

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…

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…

I chose to write about magnesium because I had taken chemistry before. I took chemistry in high school and we had a lab where we created really bright colors that are used in fireworks. One of them was magnesium. Using magnesium in this lab we created a really bright white light. This really intrigued me so I decided to do my paper on magnesium. Magnesium is not only used in many of our electronics, but it’s a basis for life in both humans and plants. The original discoverer of magnesium was…

“Magnesium was discovered by Sir Humphrey Davy in England (1755). Sir Humphrey Davy also discovered MgO and HgO. The original name of Magnesium is Magnesia from the Greek word. In 1618, a farmer at Epsom in England gave his cows water from a well, but the cows refused to drink because of the water’s bitter taste. However, the farmer noticed the water seemed to heal scratches and rashes. The words spread out. Eventually it was recognised to be magnesium sulphate, MgSO4. Until 1755, it recognized…

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…

Post Lab Questions: In the theory discussion, it was suggested that the magnesium could be weighed directly. However, in the actual experimental procedure, the mass of the magnesium was determined by an indirect measurement. Explain the advantages of using an indirect measurement to determine the mass of magnesium used. By using indirect measurement to weigh the magnesium, students get a more precise measursment. This prevents any components of the magnesium from escaping and error from the…

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…

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…
