GOAL The goal of this experiment was to separate Toluene and Hexane by distillation and gas chromatography based on their difference in boiling points. The boiling point of hexane is 69 degrees Celsius and the boiling point of toluene is 110 degrees Celsius. Three fractions were collected for both simple and fractional distillation. The first fraction was hexane since it had the lower boiling point. The second fraction was a mixture of toluene and hexane. The third fraction was toluene since it had

As stated by the essay “The steam Engine Powers a Revolution‚” inventions such as the steam engine have been portrayed as being incredible instruments that have completely transmuted the way modern technology has been developed and applied to many nations. It was conceived in 1781 by a man who looked to

The Isolation of a Fisherman The Old Man and the Sea by Ernest Hemingway presents a captivating look at the most isolated regions in the human mind. Santiago‚ an old fisherman who has not caught a fish in 84 days‚ heads out to sea alone with nothing but a bottle of water‚ bait‚ and faith in his heart. Indeed‚ Santiago’s isolation serves to highlight the capacity of the human will to go on‚ even when all luck runs out and there is no one there to help push through. One instance in which Santiago

The Fermentation and Distillation of Alcohol By Bhanupriya Chettiar 301 Group Members: Bhanupriya Chettiar‚ Rachel Min‚ Zoe Chandler‚ Bianca Main Aim The aim of the practical is to prepare ethanol by fermentation and to isolate it by fractional distillation. Introduction This practical’s aim is to prepare ethanol using two steps; fermentation and then fractional distillation. Many alcoholic drinks for example‚ brandy and whisky‚ are prepared using this method but to a larger scale. The first

2.7 Raman spectroscopy Principle: Raman spectroscopy is based on the use of a laser light to induce oscillation and rotation in human fluids containing glucose. Because the emission of scattered light is influenced by molecular vibration‚ it is possible to estimate glucose concentration in human fluids [24]. This effect depends on the concentration of the glucose molecules. This technique can measure very weak signals‚ even in human fluids. The wavelength range of Raman spectrum is considered to

DISTILLATION ABSTRACT Distillation‚ one of the most significant method for separating a liquid mixture and its components‚ is a process that relies on differences by the ease of vaporization of the components. The purpose of this process is either the separation of a mixture of volatile components from nonvolatile materials is carried out by a simple distillation in which the material is placed to distill and heated‚ the vapor from the substance is removed and condensed. In this activity

Technology and the End of Isolation Technology was one of many spectacular ways that helped Americans break free from what seemed to be a never ending time of isolation. There were so many hardships in the early years starting in 1865 that one living in those days may have not have been able to see an end in sight. Inventions as well as improvements in technology were about to be the answer to many of the physical and intellectual isolation problems of Americans. There were new methods to help

Chanelle Whitfield “Othello: The Danger of Isolation” Othello is a Shakespearean tragedy which depicts the incompatibility of military heroism and love; the danger of isolation. I personally think that Othello conveys the balance of human strengths and weaknesses amidst good and evil in society. In my opinion‚ Othello is a cultural and a racial outsider who is a bold‚ strong‚ courageous‚ naive and foolish. Throughout the play Othello represents the strengths and weaknesses in society
