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 the high boiling point of 110 degrees Celsius. Gas chromatography was also preformed

he backbone (vertebral column) is the central axis of the skeleton. It extends from the base of the skull to the bottom of the pelvis. It consists of 26 individual bones grouped into five separate regions; The vertebrae‚ twelve thoracic vertebrae‚ five lumbar vertebrae‚ one sacral bone and one coccygeal bone. (Cinnamon L. VanPutte‚ Jennifer L. Regan‚ Andrew F. Russo‚ McGraw-Hill‚ 2010.) The Vertebral column also host major curvatures; The sacral and thoracic both concaving anteriorly and the lumbar

This lab is an opportunity to observe‚ study‚ and learn about ecosystems and how the environment sustains life but in a much simpler and smaller scale which is called Eco Columns. The environmental conditions in the Eco Column could sustain life for several weeks‚ therefore over the course of the several weeks we will observe and study the interconnections between each ecosystems. A self sustaining requires components such as energy flow and chemical cycle. This experiment will evaluate our knowledge

Gas Chromatography: Purifying alcohol Introduction The goal of this lab is to understand the principles of chromatography by purifying alcohol using fractional distillation. Running standards with gas chromatography we were able to see and calibrate our data to find not only how much ethanol our alcohol attained but also what a mixed unknown sample contained. Chromatography is a way of being able to separate substances in solution that can help not only identify the analytes (the studied

ANALYSIS OF MOUTHWASH Background Information: Commercial mouthwashes are mixtures of water‚ alcohol‚ dyes‚ flavorings‚ and other compounds. In this experiment‚ you will use gas chromatography to determine the alcohol content of the mouthwash. Since the volumes of alcohol and water are not additive when mixed‚ a calibration curve must be used. It will provide the correction factor needed for alcohol-water mixtures. The calibration curve will be prepared by placing a known amount of alcohol

Coming to Conclusions The conclusion of an essay is a key factor of the overall effectiveness of an essay. Often seen as a brief summary of the paper‚ the conclusion frequently revisits the thesis of the paper‚ sometimes repeating lines or words from the introduction verbatim. This almost textbook-like format can be effective but is by no means the only option there is when a writer concludes an essay. In fact‚ the title of “the conclusion” can be quite misleading. Many types of conclusions do not

Do we listen to the demands of our guardians? or is love what drives us to make better choices? Some of us are blinded by love‚ and I for one have experienced the treachery of being bashed by my own lover. I did not see what should have been sawn‚ because I was in the meadows
