Activated carbon

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). This is confirmed since the peak is a multiplet. Also, the peak is more…

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…

Coursework 1- Carbon Fibre composites compared to traditional metallic properties Introduction Carbon fibre is a material made up of thin strips of crystalline filaments of carbon woven together to create a cloth or combined with a resin or ceramics to strengthen the material. Carbon fibre is now overtaking traditional metals in where it is being used and the reasons why will be discussed further on in the report (Happian-Smith 2001: 1). Carbon fibre composites have become the leading material…

Imagine walking through an area where you could comfortably breathe the air without worrying about the constant emission of carbon dioxide into the atmosphere. Now, imagine only being able to breath in this fresh air because American families wanted more financial support in order to pursue needs of their own. Boyce writes “The Carbon Dividend” in The New York Times in order to convey the concern of “broad anthropocentrism” ideals in American society, but more specifically in Amherst,…

The doctrines of unique worth of human beings are based on biblical scriptures and revelations. The assertions are similar to Laudato Si’s divine mind. According to Laudato Si Si’s, human beings were created in the image of God. He created man and woman in his image. The concept became the Christological basis of human dignity placing them above the other creations. Laudato Si further states that human beings are the core of God’s nature and they have a major responsibility for taking care of…

C10H8, their differing arrangement of carbon atoms in rings causes disparities in their molecular orbitals. As shown in the energy difference calculations below Table 1, naphthalene has an energy difference of -10.184 between its HOMO and LUMO orbitals while azulene has one of +6.904. The low energy difference of naphthalene FMOs would suggest that its HOMO and LUMO orbitals have relatively similar distributions of electron density among odd and even numbered carbons. Conversely, the high energy…

the essay is carbon 14 isotope. Carbon is found in all living things and is the building block for organic material, there is carbon 12, 13 and 14 and they all have different properties. This isotope was discovered on February 27, 1940 by Martin Karmen and Sam Ruben and is the most radioactive out of all carbon isotopes. The relative abundance of it is >0.1% (trace amount) and its relative mass is 14.003241. It has 6 protons and 8 neutrons. This particular isotope is found in all carbon…
