The hypothesis of this experiment is that empirical formula is going to be close to a ratio as 1:1, because that is the theoretical empirical formula for the compound magnesium oxide. Empirical formula is simplest formula for a compound, it is the smallest possible whole- number ratio of subscripts of the elements in the formula. Generally, this the same thing as its simplest molecular formula, this is generally the actual number…
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.

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…

where mCO2 is the mass fraction of CO2 in the solution, and MWsolution, MWbrine, and MWCO2 are the molecular weight of the solution, of the brine, and of CO2, respectively. Considering the definition of density as shown on 5.5, equation 5.3 can be modified to equation 5.6.
"1" /"ρ" _" solution" =("1-" "m" _"CO2" )/"ρ" _" brine" "+" "m" _"CO2" /〖"ρ" _"CO2" 〗_" " (5.6)
where ρ solution and ρ brine are density of solution and brine, MW CO2 and ρm CO2 is…
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…

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…
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…
