Using SN1 reaction mechanism with hydrochloric acid, t-Pentyl alcohol was converted to t-Pentyl chloride in an acid catalyzed reaction. The reaction took place in a separatory funnel designed to separate immiscible liquids. The crude product was extracted by transferring a solute from one solvent to another. The process of washing the solutions by phase transfer was used in order to remove impurities from the main solvent layer. Finally, the crude product was dried with anhydrous Calcium chloride and purified once more by simple distillation technique.…
hydrogen chloride has properties: Hydrogen chloride has one molecule of hydrogen and one molecule of chlorine: Hydrogen chloride has a very powerful smell. It is in the form of a gas but only when it is at room temperature which is approximately 25 Celsius and when the pressure is high. The solubility of hydrogen chloride is very high this means that it can dissolve in water quickly because it dissolves many times in its own solution (the gas form of hydrogen chloride). It is very soluble because the smaller the chain of the molecules are then the energy required in small quantities however if the chain is long then it will need more energy so that means that the longer chain will have a slow reaction and the longer the chain the chances…
Clostridium tetani is a pathogenic bacterium. It is a gram positive bacillus, which means it possesses thick cell walls made of peptidoglycan and appear as rod shaped. C. tetani is an obligate anaerobe that form spores which are resistant to heat and exposure to oxygen (Brüggemann, 2015). This ability to form spores allows the cell to survive in harsh conditions, packing everything it needs to survive until conditions improve. C. tetani is found mostly in warm, damp areas, especially in soil, but can also be found in the intestines or feces of many animals (Wells, 1983). The medical importance of bacterial endospores is significant. While it is typically pretty easy to kill off vegetative cells, no matter how scary a pathogen they may be, bacterial…
In general, members of the genus Vibrio are Gram-negative, motile and most of the members have a single polar flagellum, when grown in liquid medium (Kaysner & DePaola, 2004). Vibrio cholerae lives naturally in riverine and is the causative agent of cholera outbreaks and epidemics. Vibrio cholerae is comma-shaped. Initial isolates are slightly curved, whereas they can appear as straight rods upon laboratory culturing. Vibrio cholerae is a facultative anaerobe and can undergo respiratory and fermentative metabolism. Vibrio parahaemolyticus is a curved and rod-shaped and usually found in brackish, saltwater. Once ingested, this bacteria can cause gastrointestinal problems. Vibrio parahaemolyticus is oxidase positive, facultatively aerobic and does not form spores and same like other members of the Vibrio genus, this bacteria is also motile and has a polar flagellum (Ryan and Ray, 2004).…
Chlorine was founded by Carl Wilhelm Scheele in 1774. Chlorine's normal phase of matter is gas and it has a classification as a non metal. Chlorine is also apart of the halogens family. Chlorines boiling point in Celsius is –34.04, but the melting point is –101. Its origin is Greek. The atomic number is 17. Chlorine has 17 protons and electrons and 18 neutrons.…
As an attorney specializing in labor and employment and higher education law, Bostonian, Dana L. Fleming wrote an article entitled, “Youthful Indiscretions: Should Colleges Protect Social Network Users from Themselves and Others? The article was published in the Winter 2008 The New England Journal of Higher Education. In 2008, two social networking sites, MySpace and Facebook, were becoming increasingly popular with young people. Adolescents, college students, and people in their twenties began to expose their lives online for all the world to see. Fleming questions the role that colleges and universities should play protecting its students from the dangers of indiscrete online exposure.…
Finding a bacterium that I felt even a shred of confidence to discuss in a paper was no easy task, but while doing research I discovered this (probably more well-known than I realize) bacteria that had some properties that were incredibly interesting to me. The basic properties of Pseudomonas syringae is that it 's gram-negative, has a rod-shaped morphology, and is an aerobic respirator. It 's categorized as gram-negative due to crystal violet being washed away, and stained pink by the counter stain safranin during a gram-stain. The crystal violet can be washed away due to a gram-negative organisms thinner peptidoglycan layer. It 's rod-shappedness is merely a morphological characteristic, and doesn 't seemingly mean much in describing it 's toxicity in plants. It 's aerobic nature is characterized by utilizing oxygen to create energy. More specifically oxygen is the final electron acceptor in the Electron Transport Chain for Pseudomonas syringae which is responsible for most of it 's energy production.…

Salt is obtained by introducing water into salt caverns which in turn dissolves the salt deposits within the caverns, allowing the salt solution (brine) to be brought to the surface for further processing. The brine is boiled in order to remove most of the liquid, resulting in salt crystal deposits. The salt crystal deposits are then further dried to remove all residual moisture to produce the final product; salt. The finished product is stored within a silo awaiting production.…
