  • Mechanochemical Methods In Chemistry

    3.2 Mechanochemical synthesis The mechanochemical method was employed to synthesis CP and MgCP where calcium hydroxide (CaOH2), phosphoric acid (H3PO4) and magnesium hydroxide (MgOH2) were used as precursors. Table 3.1 shows the parameter used by varying the weight percentages (wt. %) of Mg. Table 3.1: The weight percentages ratio for magnesium doped calcium phosphate Samples Parameter Calcium Hydroxide Ca(OH)2 (g) Phosphoric Acid H2PH03 (g) Magnesium Hydroxide Mg(OH)2 (g) Undoped CP 27.7 22.3 0.00 1.0wt.% 27.7 22.3 0.50 1.5wt.% 27.7 22.3 0.75 2.0wt.% 27.7 22.3 1.00 3.2.1 Planetary Ball Mill The planetary mills are used in which it is effective in grinding of hard, medium, hard, brittle and fibrous materials in suspension.

  • 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…

  • Carbon Dioxide In Recirculating Aquaculture Systems

    The removal of carbon dioxide in Recirculating Aquaculture Systems (RAS) has been an important topic of research due to the increasing amount of recirculating aquaculture systems being employed in the aquaculture industry. Carbon dioxide, as well as ammonia, are excreted by the fish and can be present in high quantities. Elevated levels of CO2 accumulation within the recirculating water could have toxic effects on fish. The maximum level of CO2 and ammonia that can be present in the tanks…

  • Soil Characterisation Essay

    A detailed description of soil locations, textures and physio-chemical properties can be found in Sections 2.3.1(page 41) and 3.3.1(page 56). We selected four types of soils out of seven types of soils, namely MGA, KBA, TAA and DUA. Key soil characterisation of these four soils is summarised in Table 4.2. The reason why these four types of soils were chosen for this chapter was that they had distinct soil parameters in terms of total organic carbon (TOC), Fe oxide, Al oxide, pH which have been…

  • Errors In Avogadro's Law

    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…

  • 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.…

  • Grignard Reaction Lab

    organometallic compound as it includes a carbon atom bound to magnesium and a halide, usually bromine. Grignard reagents must be prepared in an aprotic solvent, such as diethyl ether or THF, because the MgBr, is a strong nucleophile and thus a strong base. There must also not be any water in the solution for the same reason. As such, the solvent must be anhydrous, the glassware must be totally dry and the humidity should be minimized. There are several other side reactions that need to be…

  • Magnesium And Hydrochloric Acid Essay

    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…
