The Unknown

To identify the unknown chemical mixture (#757), a TLC analysis was conducted using three standards (aspirin, acetaminophen, and caffeine). A TLC plate was prepared by drawing an origin line and solvent front line with a pencil. Three spot were labeled A, B, and C. A sample of each standard was spotted on the analytical TLC plate approximately 1cm from the bottom of the plate. It was then enclosed in a jar filled with 2ml of 95% ethyl acetate- 5% acetic acid. (Another laboratory group conducted…

government control of its citizens can lead to a lack of individualism. In Auden’s “The Unknown Citizen”, the Unknown Citizen has no identity, his life is very conventional in that he does not distinguish himself from any of his fellow citizens. The Unknown Citizen was always a hard worker, “yet he wasn’t a scab or odd in his views” (Line 9). Auden deliberately uses the word “scab”, to describe the qualities that Unknown Man does not exhibit. A scab has the denotation of a worker who ruins a…

The sculpture in Unknown #4 depicts the upper body of a middle-aged man. That the figure shows the imperfections which come with age suggests that the sculpture is of Roman origin rather than Greek. Carved from marble, the sculpture extends to the lower chest of the man, just above the solar plexus. The chest and shoulders are soft and lightly defined: the pectoral muscles are visible only as gentle contours, and the shoulders slope downwards in fleshy smoothness. The head of the figure is…

She also mentioned that another neighbor told her that she once witnessed one of the children outside alone walking off into the main street. She said the neighbor went and got the child and walked…

through, until you have walked in their shoes.” With Cristina Henriquez’s book, “The Book of Unknown Americans,” I felt I was as close to experiencing what the characters were going through without actually being in their shoes. Henriquez did a great job of adding details and twists while getting you emotionally attached to the characters. From the beginning I was drawn to the characters in “The Book of Unknown Americans.” By the author changing point of views each chapter, I recieved different…

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 purpose of this lab was to use NMR, Recrystallization, TLC, and Melting point to separate and identify the components of a given unknown mixture. The first step of the experiment was to use the two NMR spectra given to identify the major and minor components of the unknown mixture. When an external magnetic field is applied, there is a quantized interaction between the magnetic field itself and the magnetic moment of the proton. Thus, the magnetic moment of the proton either applies with or…

“The Unknown Citizen,” written by W. H. Auden, is a poem that describes the life of man lived a life that most people would see as ideal. The man illustrated by this poem did what society expected him to do which resulted in a model life. This poem, however, can be seen in more than one way. Some may see the story in the poem as a description of a man who had an unfulfilling life because he did only what was expected of him. Instead of trying something new, exploring the world, or making a…
