1) Petcoke is the nickname given for Petrolum Coke, a material that looks like coal and is a byproduct of refining the oil brought in from Canada. (Chicago Public Health) While no known illnesses of health effects are associated with Petcoke, they can cause breathing issues, which includes “coughing, wheezing, or shortness of breath.” (Chicago Public Health) Currently, the Illinois Environmental Protection Association Agency is investigating an open-air storage area along the Calumet River (EPA)…

Picture Caption: Beware this is a road bike other bikes with have similar components but not the same as this road bike. • Frame: The frame of the bike holds everything together and consist of the Head tube, Top Tube, Down Tube, Seat Tube, Seat Stays, and Chain Stays. • Head Tube: The head tube contains the headset, the bearings for the fork. • Top Tube: The top tube connects the top of the head tube to the top of the seat tube. • Down Tube: The down tube is connected to the head tube. Also…

spectrum, meaning that the starting material is not present. As for percent yield it was 57%, meaning that of the total possible amount of product that could have been collected under ideal conditions only 57% of that was collected. Then there is the 1H NMR, helped determine the ratio of both the cis and trans form of 2-methylcyclohexanol. A process called integration, which uses the areas under the corresponding peaks, did this. The peak for trans is at approximately 3.1 ppm and cis is…

benzene can undergo substitution reactions that are electrophilic aromatic substitution reactions. Given that benzene rings are used commonly in the production of many organic compounds, the capability to make substitutions to benzene is critical. The NMR and IR spectra results confirmed the identity of the final product. The percent yield was also reasonable.…

My element Sulfur is the most important element there is. The symbol for Sulfur is S. An yellow looking odorless substance that is found underground. Sulfur has an atomic number of 16, atomic weight of 32.065. The element Sulfur is classified as a non-mental with the boiling point of 832.28 degrees Fahrenheit and a melting point of 239.38 degrees Fahrenheit. There are several mixture of sulfur compounds, including the mineral pyrite, or iron sulfide. Each of these types of Sulfur plays its own…

The 1H NMR data strongly suggests that 3-pentanol was produced. On the 1H NMR, there are a total of 12H, which is the correct number of protons on 3-pentanol. Around 3.45ppm, there is a multiplet with an integration of 1. This peak corresponds to the methine proton on the carbon bearing the alcohol. The integration of 1 is correct since there is only one proton on that carbon. This proton has 5 neighboring protons, and is expected to be a multiplet (doublet of triples, or a triple of doublets).…

Properties; Beryllium is a toxic bivalent element; with a steel gray metallic look to it. Beryllium is also a durable, lightweight element. Primarily used as a hardening agent in alloys. It has one of the highest melting points of the light metals. With the atomic number of 4, and being classified within the group of alkaline earth metals. The element is nonmagnetic and resists oxidation when exposed to air at standard temperature and pressures. It’s also found in over 30 different minerals; for…

Fibers are everywhere in everyone. Fibers are threadlike elements from fabric or other materials such as carpet. They are mostly identifiable under a microscope, Fabrics are helpful in forensics in many ways. Fabrics are made fiber strands that are much longer than they are wide and generally round on cross section. These fibers may be from natural or synthetic sources.The main reason why fabrics are helpful is because fibers are in clothing,upholstery, carpet, rope, and building components.…

Background Benzo(a)pyrene (BaP), a polycyclic aromatic hydrocarbon(PAH) when infiltrated within the body of humans and animals undergoes a series of chemically modified changes to form a number of metabolites that are known to elicit portentous and toxic effects (4). Benzo(a)pyrene has a chemical formula of C20H12 and is considered a Group 1 Carcinogen by the International Agency for Research and Cancer (IARC) (7, 11). It is composed of a cyclic structure and crystals appear to be pale yellow…

surface is called sheen and it can kill the aquatic animals and plants that live beneath the water if it is not removed quickly. Photosynthesis uses solar radiation to change water and carbon dioxide into important nutrients that endure plant life. Therefore, plants and algae need consistent access to water, carbon dioxide and sunlight to undergo this essential process. Spilled oil floats on the surface of the water, blocking one of these important ingredients, sunlight, from reaching the…
