Experiment 15 & 16: Preparation of 1-bromobutane‚ an SN2 reaction Preparation of 2-chloro-2-methylbutane‚ an SN1 reaction Introduction The purpose of this experiment is to synthesize 1-bromobutane from 1-butanol and sodium bromide. In order for this reaction to reach completion there are four major operations that need to be performed. The four major operations include refluxing‚ simple distillation‚ separation‚ and drying. To begin‚ in order for the compounds to react they will be dissolved

twentieth most abundant element and is found in our air‚ water‚ and soil. Arsenic is usually combined with other elements‚ forming compounds with oxygen‚ chlorine‚ and sulfur; and it is in both organic and inorganic forms. Organic arsenic is combined with carbon and hydrogen‚ where inorganic binds with elements such as oxygen‚ chlorine and sulfur. Common inorganic compounds of arsenic are trivalent arsenic and pentavalent arsenic; and two reocurring organic compounds are monomethyl arsonic acid and roxarsone

Abstract This investigatory project determines the possibility of purifying used cooking oil using sedimentation method. The activated carbon was also used in the experiment to absorb some dissolved substances in the oil. There were three different setups used in this study namely; Setup 1 (sedimentation was done once); Setup 2 (sedimentation was done twice); and Setup 3 (sedimentation was done thrice). The purified oil was compared to commercial oil in terms of color‚ odor‚ and clearness using

renewable energy which means that it can be used as long as humans can and it has little pollution. People should try their best to expand the use of solar energy and to relieve the energy problems. If they use fossil fuels‚ fossil fuels will release carbon dioxide and some other polluting gas and humans cannot use them forever due to the limited resources. People should promote solar consumption with joint efforts instead of non-renewable

experiment #1 is not just an ordinary rock because it’s a calcium carbide and was known here in the Philippines as kalburo. When this chemical compound is mixed with water there will be a chemical reaction and it produces acetylene gas. The two anions of carbon‚ the carbide (C4-) and dicarbide (C22-) ions react with water to produce hydrocarbons. The carbide ion gives methane gas‚ and the dicarbide ion gives acetylene gas. This video shows the reaction between calcium carbide and water to produce acetylene

Conventional Oil Based Plastics Vs. Innovative Green Plastics The Twentieth century was filled with many inventions that have greatly influenced our world. The invention of plastic was one of the most dramatic of them all. Humans use plastics each and every day and just imagining a day without them is inconceivable. A material can be a plastic if it satisfies three conditions: its main ingredient must be a polymer material‚ it must be fluid at some point during processing‚ and it must be solid

Should Everyone Switch Completely to Electric Cars? Everyday gas powered cars destroy the environment and the people that drive these gas guzzlers pay a ton of money to use them. Many people think that gas powered cars are better than electric cars‚ but they do not know the real truth. After you read this paper you will understand why electric cars are better for yourself and the environment; you might even have to buy one! There are many credible sources that prove the benefits of having an electric

Boron is used in pyrotechnics and flares to produce a green color. Boron has also been used in some rockets as an ignition source. Boron is used to control nuclear reactions. It is an excellent neutron absorber. Alloyed with steel or reacted with carbon‚ titanium or zirconium‚ it is used in control rods for nuclear reactors Boron is an essential nutrient for all green plants Bibliography: http://chemtopics.com/elements.htm http://www.webelements.com/boron/

When the polymer is exposed to microorganisms found in soil‚ sewage‚ river bottoms or other similar environments‚ the decomposition into carbon dioxide and water may occur. Other properties of Biopol include its insolubility in water‚ good oxygen permeability‚ ultra violet resistance but poor resistance to acid and bases‚ solubility in chloroform and other chlorinated hydrocarbons‚ biocompatibility
