Carbon Footprint Essay

is a reducing agent that is able to reduce ketones and aldehydes. In this case, camphor, which contains a ketone, was reduced with sodium borohydride. Reduction of a carbonyl with sodium borohydride occurs when the hydride ion adds to the carbonyl carbon, breaking the C=O bond and creating a new C-H bond. When the reduction occurs, the hydride transfer will occur on the less hindered side of the carbonyl group. This addition will usually create the more hindered alcohol but will generally create…

5-CinthiaV-Selenium The name of my element is Selenium. The element symbol is “Se”. Selenium was discovered in Sweden by Jons Jacob Berzelius in 1817. Selenium is an origin for a greek word meaning moon. Selenium has four energy levels. In the first energy level, it has two electrons. The second energy level has eight electrons. The third energy level has 18 electrons. The fourth energy level has six valence electrons. Selenium has forty-five neutrons. Selenium has the…

Reduction involves increasing the number of carbon hydrogen bonds by adding hydrogen across a double or triple bond which results in an increase in electron density at the carbon atom. Organic functional groups containing double and triple bonds which undergo reduction are unsaturated. The reduction of the double bond by addition of hydrogen atoms results in the product being fully saturated. Metal hydride reducing agents that have different reactivities toward specific functional groups are…

The World witnessed a struggle for the control of oil in 1973, the decisions of which ultimately lead to globalization. As America saw the pace of life quicken in the twentieth century with the use of cars, planes, airplanes and appliances, the demand for oil to fuel this development increased. Believing that there was endless energy, the American way of life had an insatiable appetite for oil. Up until 1950 the United States had been able to supply its own energy needs, but in less than 25…

In 2010, St. Patrick's Day started out as a normal day for Jamie Laiaddee. She had gotten her oiled changed at Greulich’s Automotive, local mechanic, and was expecting to start her new job the next day a year after being laid off. The 32 year old had no idea that she would drop off the face of the earth. A California girl, Jamie was born in Los Angeles on October 12th, 1977. Her family, of Tai decent, had made the decision to move to the United States in search of a better life. Jamie was a…

given case study also results in the reconsideration of the carbon footprint of banana and introduces the main aspects of the production of this product. According to it, there are three main environmental concerns related to bananas, their distribution and usage. These concerns are the process of transportation of the product to the markets; the production and the package. These factors have the significant impact on the carbon footprint of banana and result in the increase of the awareness…

When dinosaurs ruled the earth, the climate was most likely humid and warm. The carbon dioxide in the atmosphere was close to present day levels. Scientists found that the reasons of extinction of dinosaurs have linked to the global warming. Changes in climate would have occurred due to the disruption of wind and ocean currents. These marine changes, combined with volcanism and an extraterrestrial impact, may have caused the mass extinctions. (Dinosaurs Climate Change and Biodiversity) Similarly…

An ecological footprint is a tool of resource accounting that indicates the extent of how land or sea is biologically utilized by a particular activity or population by making a comparison to the open sea and land. Sea and land space that is productive supports the demands of human beings such as food, energy, and timber. An ecological footprint is capable of measuring the total of the human demands in their natural occurrence across the planet. Also, it can address the question of the extent of…

Coursework 1- Carbon Fibre composites compared to traditional metallic properties Introduction Carbon fibre is a material made up of thin strips of crystalline filaments of carbon woven together to create a cloth or combined with a resin or ceramics to strengthen the material. Carbon fibre is now overtaking traditional metals in where it is being used and the reasons why will be discussed further on in the report (Happian-Smith 2001: 1). Carbon fibre composites have become the leading material…

The human body is mainly made up of four elemental components: oxygen (65%), Carbon (18%), Hydrogen (10%), and Nitrogen (3%). It is also composed of about 28 other elements including, Potassium, Sodium, and Calcium. Each plays a major role on the daily functions of the human body. Oxygen accounts for roughly about two-thirds of the mass of the human body and is use in cell respiration. Carbon is part of the molecular structure in certain fats, proteins, and carbohydrates; which are essential…
