    (Maximum length 1 page including chemicals equations) 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…

    There are five common ways to predict the product of chemical changes. They are synthesis (composition), decomposition, single replacement, double replacement, and combustion. Each can be used for different types of problems based on the equation of experiment presented to you. They can also be found using observations throughout the experiment. You use these base guidelines to write a well balanced equation with physical states and all of the reactants and products that are produced. Our…

    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. ρ_CO2=MW_CO2/V_CO2 (5.5) "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…

    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 percentage composition also calculated in…

    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…

    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…
