    Magnesium is a mineral that can be described in so many different ways. It is almost impossible to name every little thing that magnesium may assist in to help our body function. To start with, magnesium is roughly involved in 300 essential reactions that happen within our body. The adult contains about 25g of magnesium in their body. Magnesium has specific recommended consumption level. If there is not enough magnesium in the body, it can cause multiple problems or illnesses. The same applies…

    1. The reported mole ratio of magnesium to oxygen will be too high. The experiment will have less oxidation while burning. Since there are 2 oxygen and some of the magnesium evaporates as it burns, the ratio will be higher than usual 2. Since there are some magnesium present at the end of the result from not allowing all of magnesium to react and oxidize, the ratio of Mg:O will be too high -Source of error: The first source of error happened when students lifted the lid off, sometimes he/she…

    Johan Gottlieb Gahn, a swedish chemist, heated the mineral pyrolusite (MnO2) and in the presence of charcoal, found element 25, manganese in the year 1774. This silvery-metallic element has an atomic mass of 54.938049 rounded to 55 with 7 valence electrons. Manganese is a transition metal in group 7, period 4. Manganese is very flammable and dangerous with very strong intensity! It’s found in the earth’s mantle while having a melting point of 1246℉. The element manganese stimulates functions 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…

    Nanocrystals (NCs) are interesting material, as their electrical and optical properties can be tuned by tuning their size or surface area. They have diverse applications in electrical devices. Nanocrystal thin film transistors (NC TFTs) have been intensively researched, because of their low-temperature processability.1,2 Colloidal NCs are synthesized in a liquid solution containing some stabilizing organic molecules, broadly termed as surfactants, which are bulky and insulating ligands. The…

    Magnesium Research Paper

    “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 aim of this experiment was to determine the percentage composition of magnesium and oxygen in magnesium oxide and evaluate if the composition varies or remains constant. To test this, magnesium was heated and made to react with the oxygen gas in the atmosphere. This reaction formed the ionic compound, magnesium oxide. The percentage composition was later calculated based on the results of the experiment as shown in the above calculations, Figure 4. These results were compared to the expected…

    Some issues regarding emissions include the Volkswagen Scandal which involved the German company activating emission controls to meet laboratory test standards with nitrogen oxides, but in real driving emit up to 40x more; test manipulation is a growing problem in the world today (EPUK 1). As a result of test manipulation, millions of vehicles on the roads in the US and all over the world are operating without properly certified…

    In particular, selecting noble electrode materials is the hottest topics in the LIB field. Among them, bulk metal oxide such as Fe2O3, SnO2, ZnO, and In2O3 are promising material owing to their high theoretical capacity (~1000 mAh g-1), which considerable exceeds those of commercial graphitic anodes (372 mAh g-1).7–11 However, low electrical conductivity, huge…

    The software activated full emissions controls during testing but reduces the effectiveness during regular driving. As a result, the cars emit nitrogen oxides at up to 40 times more than the allowable standard. The software enables cars to get better fuel economy at the cost of higher nitrogen oxide emissions (Boston et al., 2015). Volkswagen tried to sell their cars saying their cars had better performance and lower emissions but they did not mention the nitrogen emissions…
