Carbon copy

reactions happening all the time and you don’t even know it. Some of the ways that the elements are distributed throughout the body are in the bones, blood, metabolism, genetics, and even diseases. In fact, the human body is composed of 65% Oxygen, 18% Carbon, 10% Hydrogen, 3% Nitrogen, 1.5% Calcium, and in smaller amounts of several other elements. Bones make up the skeleton of the human body. They are composed of a collagen rich mixture of calcium and phosphate, which are both elements…

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…

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…

Theq element on the Periodic table that is best representation of my personality would be element 13, Aluminum. Properties of Aluminum its included high melting point, conductivity, malleability, and non-toxicity. Aluminum’s high melting point represents my determined personality. This is because I can face adversity well. Even when situations occur that are extremely unfavorable I am able to keep a cool head and think straight. I can persevere and stay strong allowing myself to solve and get…

Experiment 5: Anions and Redox Reactions Introduction (a) Objectives General: To examine the importance of potassium permanganate as an oxidising agent and the strong powers of halogens in oxidation. Part 1 Determining the colour associated with a certain halogen by adding a sample of the halogen to cyclohexane and recording the colours observed. Part 2 Identifying a halogen referring to the colours recorded in part 1, by reacting the halogen with a halide and observing the colour present.…

3.4. Friction Characteristics of the NCD, MCD and boron doped NCD Coatings against Alumina Balls The friction coefficient curves of NCD, MCD and boron-doped diamond films sliding with Al2O3 balls are shown in figure 4, figure 5 and figure 6, respectively, for a sliding speed of 8 m/s and a load of 1N, 5N and 10N, respectively. Figure 4 (a), figure 5 (a) and figure 6 (a) show the friction coefficient of NCD, MCD and BDNCD at 1 N, respectively. Figure 4 (b), figure 5 (b) and figure 6 (b) show…
