burning. However, in case water is used when removing the residues even after several days, the fire may reignite. The water will firstly expose the surface of the magnesium residues to reaction and react with it (magnesium) to release flammable hydrogen gas hence reigniting the fire. The fire will be accelerated by the oxygen in the air making it more intense and dangerous. The more the surfaces of the magnesium are exposed the higher the intensity of the fire. It is advisable not to use water…

“The Law of Conservation of Mass states that matter can be changed from one form into another, mixtures can be separated or made, and pure substances can be decomposed, but the total amount of mass remains constant.” (University Of Wisconsin) The data the was found from our lab shows that the data is not consistent to the Law of Conservation of Mass because our results showed an increase in mass. To start the lab, .7 grams of copper was measured out and at the end, the total amount of copper was…

There are numerous scientists who have positively impacted the field of Chemistry; from Robert Bunsen to George Washington Carver, chemists have and continue to shape the publics knowledge of Chemistry. However, one chemist stands out from all the rest because of his historical, societal, and person significance: George Claude Pimentel. Pimentel’s life, work, and contribution to Chemistry have shaped this field and impacted it in ways that other scientists have not. Background George Claude…

Discussion In this experiment, the chemical reaction between acetone (CH3COCH3) and iodine (I2) to make CH3COCH2I, I-, and H+ was observed. Under normal circumstances, this reaction would occur very slowly. In order to speed up the process, hydrochloric acid (H+) was used as a catalyst. A catalyst is a substance that can speed up a reaction by lowering the activation energy of the reaction. It does this by changing the mechanism of the reaction and providing more energetically favorable…

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…
