Azo compound

Research Paper Honors Chemistry Group Number 8 Research Paper The science fair topic at hand is whether or not chemical compounds affect water 's heat resistance/reception. In other words, how does the temperature of water (H2O) change when chemical compounds - such as sodium chloride and sucrose - are added? In this experiment, the independent variable is the chemical compound being tested while the dependent variable is the temperature of the water. The constants are the surface being…

which was about 10,000 years ago in the Fertile Crescent. However, pesticides have not always been an organic compound. The first generation of pesticides was composed of inorganic substances, such as sulfur, mercury, lead, arsenic (calcium arsenate and lead arsenate), and ash. The modern era of pesticides was developed in 1940, around the time of World War II. Organochlorine compounds, such as dichlorodiphenyltrichloroethane (DDT), was the first synthetic organic pesticide to be introduced.…

structure of an unidentified compound that was discovered in a local landfill. The group was called in to help determine the chemical and physical properties of the compound so we can let the people of the town know so it can be taken care of properly with or without further precautions to be taken. Another goal of this project was to devise the synthesis of the unknown compound. Experimental Design In order to determine the correct identity of our unknown compound, we first started with a…

Have you ever thought about how fascinating it is that one familiar smell can bring back so many memories? The smell that can bring me back to my past and fill my heart with joy from the memories. The biggest memory that peppermint brings back for me is my Grandma. My Grandma was an amazing woman, she always wore a certain perfume and still to this day I am not entirely sure what the perfume was but it had some type of peppermint fragrance to it. My Grandmother and I used to do everything…

In this experiment one, are determining the melting points of different crystalline substances following a specific procedure. By finding the melting point of a crystalline substance, it helps determine what kind of compound it is as well as initiate the purity. A DigiMelt apparatus can be used to determine the melting point where a small amount of the the substance is packed into a capillary tube and heated slowly in the apparatus which includes a thermometer, a heating coil and a magnifying…

properties pave the way for future research in inhibitor technology. Introduction The inherent protection of metals and their alloys used in industry are of the upmost importance when it comes to longevity and reliability of structures. Many chemical compounds have been developed over the years that can inhibit the corrosion rate of metal alloys but cost effectiveness, toxicity, processibility and other factors limit the applications1. The need for new, eco-friendly and cost effective corrosion…

pesticide residues, waste solvents, fly ash and process sludge” (Philip, et al. p 313-314). About 6,900 tons of lindane (hexachlorocyclohexanes), 2000 tons of chlorobenzene, 200 tons of dioxin-contaminated trichlorophenol, 2400 tons of organic sulfur compounds (e.g., lauryl mercaptans), 2400 tons benzylchlorides and 2000 tons sodium sulfide/sulfhydrates” among others were been buried in the love canal over a ten year period. (Gensburg, et al. 2009, p 209; Kim, 1981…

release fewer lights per unit area than inorganic solid-state based LED point-light sources. Introduction-An OLED (organic light-emitting diode) is a sort of LED (light-emitting diode), where the emissive electroluminescent level is a film of organic compound which releases light in response to an electric current. This layer of organic semiconductor material…

Introduction (succinctly) The mass media embodies a distinct symbolic system of expression for delivering messages to audience. Semiotic analyses on advertisement expose cultural norms and values associated with a particular society or group of people. The semiotic concepts of the icon, index and symbol must be carefully considered when analysing the media. “Semiotics highlights the way that we ourselves take part in the creation of meaning in messages, suggesting that we are not mere bystanders…

Some of the largest contributors to volatile organic compound emissions are carpet, mattresses, particle board, wood stain, and paint. When it is time, there are many natural mattresses, stains, and paints available that have no or low amounts volatile organic compounds. Flooring should be replaced with hardwood, lament, or stone. These flooring options do not require adhesive or synthetic materials and are easily…
