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…

FePO4 stands for Iron(III) Phosphate. Although α-FePO4 and β-FePO4 may sound quite similar as they may only differ in terms of the α and β, they β are actually very different in terms of the crystal structures and crystal chemistry of quartz. Based on the research article which was provided in coursera, it states that FePO4 is studied across a range of temperatures ; 294K to 1073K by neutron powder diffraction. The different range in temperature shows different structures. For instance, at…

“With increasing degree of calcification, the concentration of NaOH increases. The relationship between the concentration of NaOH and the factors in the calcified red mud liquor is given by three Equations (16–18): N_NaOH=1.29(N_1 m_1-N_2 (m_2-N_NaOH/1.29) (16) m2 = m1+m1N3 (17) r = 1000/m2…

recorded infrared spectrum and the researched infrared spectrum from the SDBS website (see attached). There were peaks shown to represent aromatic carbon to hydrogen bonds at 618cmˉˡ on both IR spectrums. Peaks were also shown at 3015cmˉˡ on my products recorded IR spectrum and 3016cmˉˡ on the SDBS IR spectrum that represented the carbon to hydrogen bond stretching. There were many other identical peaks which can be observed on the attached infrared spectrums that provide assurance of my formed…

component ( i ) Cn: The total number of carbon atoms Cni : Number of carbon atoms for component ( i ) H_m = ∑ X_i H_mi (3.3) Where: Hm: The total number of hydrogen atoms Hmi : Number of hydrogen atoms for component ( i ) CnHm : The average chemical formula So the average chemical formula has been determined as in the above equations according to the percentages of each components for Iraqi light naphtha which have…

3.3. Mulliken Atomic charges analysis Mulliken atomic charge calculation has an important physical property of the quantum chemical calculation of molecular system because of the atomic charge effect, electronic structure and more a lot of properties of molecular systems [19].The possible molecular bonding of a compound depends on the electronic charge existing on the chelating atoms [20]. The charge changes with basis set presumably occur due to polarization. The charge distribution of (C20 is…

Fatty acids and oil are organic substances, which are composed of carbon, oxygen and hydrogen. When carbon, oxygen and hydrogen are chemically combined with a carboxyl group, a long chain is formed, called as fatty acids. Alternatively, when fats react with water, they break into fatty acids and glycerin. Three chains of fatty acids when react with glycerol molecule, they combine to form triglycerides. Molecules of triglyceride are the basis of fats and oil. The difference in their chemical…

Paragraph 1 (300 - 500 words) Compare and contrast the crystal structures and crystal chemistry of quartz, α-FePO4 and β-FePO4 To compare quartz, α-FePO4 and β-FePO4, it is essential to look at their crystal structures and crystal chemistry. This can be done by observing their three-dimensional structures as well as their reactions to various degrees of temperature. This particular research takes a look at the structure of FePO4 between temperatures of 294K to 1073K. At lower temperatures,…

Paragraph 1 This essay will evaluate the Haines et al. Also, the essay will discuss about how the structure of FePO4 will change at various temperature ranging from 294K to 1073K. FePO4's A cation is a transition metal, thus it is not the same as other α-quartz isotopes. FePO4' has α-quartz structure which is tetrahedral when it is at a very low temperature. Under huge pressure, FePO4's structure goes through a phenomena called β-phase which it became a more condensed octahedral structure.…
