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…
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…
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…
Identification of an Unknown Compound to Determine Proper Waste Procedures Department of Chemistry, Michigan State University, East Lansing, MI 48823 October 13, 2015 For completion of CEM 161 Section 009, under supervision of Abstract: In order to determine the identity of the compound we performed many experiments with a solution of the compound. These experiments included testing for all of the following ions; ammonium, halide, sulfate, carbonate, nitrate, and acetate…
Identifying Unknown Substance. Examining the physical characteristics of the available compounds in the lab was how possible compounds were eliminated from any or further testing. Based on how the compounds physically looked, it was almost for certain that calcium chloride was the unknown compound. However, another compound was used to test as well (ammonium chloride) since relying only on physical characteristics alone would not allow for proper experimentation. The unknown ended up being…
I am a mixture. A mixture of the habits I have developed from those closest to me, the cultures of my ancestors and my parents, along with interests that are ever growing. Among these there are a few that were instrumental in the discovery of both myself and what my future held in store. For the past 17 years I have grown up in a household that was much larger than one roof could cover. I was raised by my parents, my tías, and my teachers, and from each have learned something valuable. Through…
chemical compounds on Earth and even more being discovered or synthesized each year, it is increasingly difficult to identify compounds.1 However, with the help of physical and chemical properties of the atoms or molecules that make up a compound, identifying a chemical compound is not as daunting as it may seem. There are three main types of chemical compounds: metallic, covalent, and ionic compounds.2 In this experiment, however, the unknown compounds are specifically ionic. An ionic compound…
