In the case of Anna Garcia, many important pieces of information were uncovered with various forms of analyses. In this case, the cause of the death of Anna Garcia is being investigated, along with reasons. Various important clues from the crime scene give hints as to what Anna Garcia’s demise was, among them a hypodermic needle on the floor. Another important piece of evidence at the crime scene is the presence of blood in a puddle, along with some drops. In addition, there was a pile of barf…

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…

The previous lab that was conducted dealt with oxidation, which is referred to as a compound gaining oxygen or losing electrons (Wyman, 2015). This week’s lab consisted of a reaction that was the opposite of an oxidation and it is known as a reduction reaction. To be more specific a reduction reaction is when the reactant that is present gains electrons, which is response lowers the overall formal charge of the compound. For instance, if there are two hydrogen ions and each one has a positive…

The goal of this lab was to prepare methyl m-nitrobenzoate using electrophilic aromatic substitution. An example of electrophilic aromatic substitution is nitration where a hydrogen atom which is part of a aromatic ring is substituted by an electrophile. For benzene, aromaticity is a stabilizing feature. As such, instead of undergoing electrophilic additions, it undergoes electrophilic substitutions. The nitronium ion is the electrophile which gets attached to the electron rich aromatic…

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…

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…
