    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 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…

    mixture of wet and dry depositon that contain high amounts of nitric and sulfuric acids (see Figure 1). These gases come from electric generation, factories, forest fires, burning fossil fuels and acid rain forms when these gases react with water, oxygen and air. Wet deposition happens when acid chemicals fall to the ground in a rain or snow for although dry deposition happens when acid chemicals fall to th ground in a dust or smoke form. The strength of an acid rain is determined by measuring…

    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…

    Oil and water are two different concepts that are believed to not mix. Normally, when pouring oil into water or vice versa, the two separates instead of mixing. However, when they do mix, both oil and water complement each other. The concept of the three main religions, Judaism, Christianity, and Islam, can be explained through the idea of oil and water. When these religions mix, they create something special. Each religion has two different ways of viewing God even though it is the same God. In…

    The Brukunga Mine site lies above Brukunga Township in South Australia, located 4km north of Nairre and 40km east of Adelaide, Mount Lofty Ranges. The operation of iron sulfide (pyrite and pyrrhotite) quarrying in Brukunga mine occurred between 1955 and 1972 (PIRSA, 2005). The manufacture of sulfuric acid in fertiliser industry caused the production of superphosphate fertilisers. The sponsorship from the state and federal government for the development of the mine provided employment and…
