  • Temperature Lab Report

    1 WRITTEN ESSAY Paragraph 1 The FePO4 crystal is examined at various temperatures ranging between 294K and 1073K by neutron powder diffraction. At relatively low temperatures, FePO4 adopts an α-quartz structure, which is tetrahedral. High pressures causes a phase change to a more dense octahedral structure, which is known as β-phase. The transition temperature is 980K. Cutoffs can be observed during the firstorder transition,. For α-phase, the increases in cell parameters…

  • Amylase Lab

    Amylase Laboratory Report Introduction: Enzymes are a catalytic protein in a quaternary structure, that helps with the acceleration of molecules called substrates to achieve its desired chemical reaction. In this lab we used a specific enzyme called amylase. According to the lab manual, amylase is an enzyme found in one’s saliva or the pancreas to accelerate metabolism and cause a spontaneous reaction that helps with digestion of a substrate called starch. In order for any polymer such as…

  • Influence Of Enzyme Thermostability

    Lipases from thermophiles are expected to play a significant role in industrial processes, since they are thermostable and resistant to chemical denaturation. Thermostable lipases are employed in various industries which includes food and diary, fat and oil modification, detergent, cosmetic, pharmaceuticals, organic synthesis, oleo-chemical and biodiesel production. The high potential of lipase application in various industries has resulted in increasing demands for new lipase which is…

  • Tartarin Melting Point

    Abstract: The melting point ranges for the substances Tartaric Acid, Acetaminophen, and Phenacetin, which are in powder form and white in color, was found and compared to their literature values to find their purity. The melting point range of a 9:1 mixture of Phenacetin and Tartaric acid was later found to show the effect an impure substance has on temperature. Melting point range for unknown three that was lastly tested was matched to Acetaminophen by comparing their melting points.…

  • Lab Report Cyp1a1

    Additionally recent studies indicate that this enzyme is highly contributed in the detoxification and protection of the organs or parts of the body that are exposed to carcinogens chemicals. For example, it has been found that this enzyme is highly active in smokers than the non-smokers in order to metabolize the chemicals in lungs however the exact function of this enzyme in lungs is not determined yet. In fact it has been found that CYP4501A1 has this type of protective function in skin and…

  • Enthalpy Of Neutralization Lab Report

    Research Question: To compare the enthalpy change of reaction of 3 neutralization reactions by using 3 different acids of distinct pH. The same base of NaOH will be used in all three experiments. Introduction: Chemical reactions always have energy change. Energy in the form of heat, if liberated is known as exothermic and if absorbed in the reaction is known as endothermic. When a reaction carried out under standard condition at a of temperature 298K and 1 atm of pressure and 1 mole of water…

  • Hydrogen Sulphid Test

    1.7.3.4. Hydrogen sulphid test (MacFaddine, 1980): Tubes of triple sugar iron agar media were inoculated by suspected culture through stabbing into the butt and the slant then covered with sterile melted paraffin wax and incubated anaerobically for 48 h at 37°C, appearance of blackening in the butt indicates H2S production. 1.7.3.5. Sugar fermentation test (Willis, 1977): Suspected culture was inoculated to 1% peptone water tubes containing 2% bromocresol purple and 1% quantities of the…

  • Sn2 Reaction Lab Report

    Leaving group: A specie with electron deficiency or positive charge, negative charge i.e Cl- What is SN1 Reaction:- SN1 indicates the unimolecular nucleophilic substitution reactions. Their rate determining step of the mechanism depends on the decomposition of a single molecular species (substrate). So the rate of an SN1 reaction can be expressed by: rate = K [R-LG] Furthermore, SN1 is a multi-step reaction, which forms an intermediate and several transition states…
