Carbon-14

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.…

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 transformation temperature is strongly influenced: by the interstitial elements oxygen, nitrogen, and carbon (alpha stabilizers), which raise the transformation temperature; by hydrogen (beta stabilizer), which lowers the transformation temperature; and by metallic impurity or alloying elements, which may either, raise or, lower the transformation temperature…

THEORY Injection molding is the most commonly used manufacturing process for the fabrication of plastic parts. A wide variety of products are manufactured using injection molding, which vary greatly in their size, complexity, and application. The injection molding process required the use of an injection molding machine, raw plastic material, and a mold. The plastic is melted in the injection molding machine and then injected into the mold, where it cools and solidifies into the final part.…

Polymer - A word, which is connote for large molecules (that a molecule made from simple repeating units called monomers). The monomers are main building block of polymers. Polymers play an essential and ubiquitous role in everyday human life because of the extraordinary range of properties. Polymers are among the most widely used and important type of materials today. Polymers have been with us from the beginning of time; they form the very basis (building blocks) of life. Animals, plants all…

spacecraft carbon nanotubes are expected to used. Rocket propulsion, of course, includes combustion. Combustion is where a substance reacts with oxygen and gives off heat. The source of oxygen is called an oxidizer…
