Introduction In class, a series of experiments were performed that pertained to the enzyme known as catalase, which converts hydrogen peroxide into oxygen. Due to peroxide being toxic to the tissues of both plants and animals, both possess the enzyme catalase, which breaks into two non-toxic compounds: water and oxygen gas. Enzymes are proteins that react to certain substrates to create a product, and continue doing so afterwards. Methods and Materials To test reactions between catalase and hydrogen peroxide, groups of three to four people were formed.
In this lab, the oxidation of a secondary alcohol was performed and analyzed. An environmentally friendly reagent, sodium hypochlorite, was used to oxidize the alcohol, and an IR spectrum was obtained in order to identify the starting compound and final product. The starting compound could have been one of four alcohols, cyclopentanol, cyclohexanol, 3-heptanol, or 2-heptanol. Since these were the only four initial compounds, the ketone obtained at the end of the experiment could only be one of four products, cyclopentanone, cyclohexanone, 3-heptanone, or 2-heptanone. In order to retrieve one of these ketones, first 1.75g of unknown D was obtained.
An oil spill is a release of a liquid petroleum hydrocarbon into the environment, it is a form of pollution that tends to be caused by human mistakes or carelessness. When oil is being transported across the ocean though pipelines or by ships there is a lot of room for accidents to happen. Accidents involving tanks, pipelines, drilling rigs and storage facilities are very common, but the attention tends to revolve around the bigger, catastrophic spills rather than the little ones that happen frequently (Kaushik, 2016). There are on average 70 spills happening every day, mostly insignificant, but still worth preventing. (Biello, 2013)
This catalyst is necessary for an aerobic organism to survive in aerobic conditions. After the experiment it was observed that my Gram positive organism did in fact bubble and utilize catalase. The third test conducted was on the MSA agar. This test was conducted for the purpose of selective and differential whether or not my organism can tolerate high salt concentrations. It is based on the mannitol fermentation.
The effects of oil spills on marine life is slowly killing certain species and marine life is and oceans are essential to human life. This issue does not just affect the oceans but the whole earth. Oil spills can take many years to clean up and most of the oil is never completely removed. Frost notes, “removing oil from the ocean in an extremely difficult task” (n. pag.). Because oil spills are so hard to clean up it continues to sit on top of the water and
To extract and produce the oil from the sands, carbon is released into the air 17% more than that of conventional oil. The increasing carbon emissions in the air can speed up the changing climate, and can lead to severe health risks. Pollution is a result of extracting this alternative oil, but
Salem Abdullah Alazmi S00036124 Dr. Buckton-Tucker ENGL 102-05 May/4 Annotated Bibliography The earth is surrounded with oceans, oceans covers around 70% of the earth. With this number of oceans, all of it is effect by pollution.
There’s a vast amount of issues going on in the state of Texas and no one seems to make an innovation. One of the biggest issue in the state of Texas is pollution in our cities. Based on my outside knowledge, no person seems to bother to make a change in our ecosystem. People seem to care less on how our environment’s health is and focus more in themselves, which is causing a more serious problem. Maybe not in that same time, but thorough the years, it’ll not just cause an issue in our environment, but also among ourselves. As an example, air pollution has been one of the main issues we face and choose to not attend.
Most companies have their downfalls throughout their history that are either due to natural causes, or due to poor management. The Exxon Valdez oil spill is no exception to this. This particular oil spill has had Exxon Valdez oil spill was an environmental catastrophe that caused lasting effects on the Exxon company, environment and the people who live and depend on the prosperity of the area. On March 24, 1989 the Exxon Valdez tanker loaded with oil entered Prince William Sound, Alaska. Joe Hazelwood was in charge of piloting the 986-foot vessel. The internal events that prior to the spill aren’t exactly clear but what was clear was that people who were put in charge for the Exxon Valdez tanker were negligent. The vessel had traveled outside
Studies examining the effect of oil exposure on polar bears indicate that upon petroleum or fuel exposure, polar bears absorb bulk of oil in their hairy coat. After the physical contact, polar bears can metabolize sufficient quantity of oil, causing kidney malfunction, digestive system imbalance, and brain diseases that lead to death. Removal of thick blanket of hair, and skin and eye irritations are few of the other harmful effects (“Polar bears and oil developments”). Species like polar bears and seals are able to absorb oil across their skin, via gastrointestinal tract, or by inhalation. Once absorbed, it spreads to all tissues in varying quantities.
the Crude oil also known as petroleum. Crude oil composed naturally from that remaining part of plants and creatures that died millions years ago and fell underneath of the see. Unrefined (Crude oil) contain hydrocarbons and alkanes in it. The hydrocarbon indicates that crude oil only made of hydrogen and carbon atoms. The hydrocarbon has different structure (straight chains, branching, and rings).
The crude oil is heated in a tall cylinder called fractionator for at least 350 degC. The process is based on the principle that different substances boil at different temperature. The cyclohexane content of naphtha fraction of crude oil can vary from 0.5 to 5.0 volume %. N-hexane, isohexanes, methyl cyclopentane, benzene and dimethyl pentanes have normal boiling points very close to cyclohexane.1 Advantages: 1. Uses a simple method of cyclohexane recovery. Disadvantages: 1.
It is commonly known throughout human history that the energy used is burned from coal which creates biomass. During the Industrial Revolution, coal was an essential need to everyone, hence the discovery of oil as a substitute. Yet, the mass formation from the unearthing of oil causes more damage than benefits for the planet. Humanity had never seen a more compatible source in which came a higher demand for oil. As the public has urged to generate more oil, scientists theorized that fossil fuels will eventually run out, making way for a renewable energy route in the future (Mason).
