Extraction was the main method of removing compounds from the sample. The component X was removed from the sample by first adding the organic solvent dichloromethane to the test tube. After aggravation, the component X dissolved into the solvent. Since components Y and Z were insoluble in the organic solvent they remained as solids. The test tube was then placed into a centrifuge and ran for thirty seconds. By doing so, the unsettled solid were forced to accumulate at the bottom of the test tube…

product in the lab. They have the ability to do this due to the molecules of the dyes possessing conjugation. Conjugation is defined as p-orbitals overlapping which causes the electrons within to be delocalized; it is also seen in molecules and compounds that contain alternating double bonds. Systems that possess conjugation absorb energy in the ultraviolet-visible region of the spectrum to cause excitement of electrons and the transitions. When the electrons get excited, they jump from lower…

Identifying an Unknown Compound Using Various Chemical Analysis Techniques Joshua Nash and Aquilla Young Abstract The introduction of this lab report exposes the reader to the different scientific concepts that are to be used such as melting point calculations, retention factors, and solubility in various aqueous solutions. The experimental provides the basics of using a melting point apparatus, determining solubility, and performing thin layer chromatography. In the results section the findings…

the lab was to identify an unlabeled compound found in the chemistry stockroom to be able to dispose of it properly. This lab demonstrated the process of identifying an unknown compound as well as synthesizing the compound. Identifying the compound consisted of performing various tests to detect the chemical and physical properties of the compound and comparing it to the list of possible compounds. The tests conducted were the solubility test which the compound fully dissolved in water, the…

The Effect of Incongruent Background Color on Odor Perception The olfactory perception is the one sense that is the most difficult to describe in words. It is also a rather personal sense since people connect scents with certain memories or images of their lives. When people are asked to imagine the scent of lavender, some might think about their mother’s laundry detergent that smelled like lavender, which she used when they were younger. But to imagine scent without thinking of an actual image…

found at different levels in some food products and in animal fat and fatty human tissue. Dioxin refers to a group of chemicals where molecules have two oxygen atoms that replace two carbon atoms, caused by the burning of chlorine-based chemical compounds with hydrocarbons. It contains…

Cannabinoids are chemical compounds that repress neurotransmitters in the brain. Repressing the neurotransmitters in the brain the body responds in a different type of way. The compounds attach to the different neurotransmitters and make your body block out different feelings such as pain. These cannabinoid chemicals are the most important part of the plant…

In one of the passages of Beloved, Toni Morrison mentions the fragrance of cologne in Denver's hideout, “Denver's secrets were sweet. Accompanied Everytime by wild veronica until she discovered cologne . The first bottle was a gift. The next she stole from her mother and hid among the boxwood until it froze and cracked.”(pg. 30) The cologne symbolizes Denver's sweet secrets, as she could contemplate her private thoughts without being judged in her hideout that contained the sweet fragrance of…

Inside a busy city there lays a large portrait, housed within a museum of modern art. To the untrained eye, there is nothing particularly extraordinary about it, but experts claim it is worth millions. All the while, in the outskirts of the city, a gorgeous, sprawling mural covers the side of an abandoned building, catching the attention of everyone who catches sight of it, yet it is labeled as vandalism, as mere graffiti. What is the role of art in our modern society, and what is the true…

Income and expenses – the fundamentals to financing projects. Once the source of income has been decided, properly determining and evaluating all necessary expenditures for a proposed project is essential. In order to maintain proper accounting a capital budget is needed. This capital budget, as it is defined by Investopedia is “the process in which a business determines and evaluates potential expenses or investments that are large in nature” (para. 1). The Federal Government must be as…
