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

SEPARATION OF POWERS IN INDIA Name: Navya Chopra Roll no.: 42 Section: B ACKNOWLEDGMENT I am glad to present the project on “The Separation of Powers in India”. This project would not have been completed without the support of my family and friends who encouraged and challenged me throughout. Who shared and exchanged ideas for the completion of the project. They never accepted less than my best effort. I would also like to acknowledge and extend my heartfelt gratitude to my teacher

enumerated powers‚ reserved powers‚ and concurrent power. Enumerated powers are only powers for the National government. Reserved powers are powers only for the state government. Concurrent powers are powers for both state and national Government. This separation of powers was due to the people making sure that no one had more authority than others. This took away some responsibilities but it also gave states the chance deal with their needs the way that they wanted. The Enumerated powers belonged only

ORIGIN OF S.O.P.- ARISTOTLE Its origin can be traced back to Aristotle‚ the father of Political Science. Of course he did not discuss the issue in great details. He only analysed the functions of the three branches of government‚ the deliberative‚ executive and the judiciary without suggesting their separation.

mobile phase can be liquid‚ gas‚ or supercritical fluid. How Does Chromatography Work? Chromatography is a surface effect. It works by first starting off with an unidentified liquid being injected into a column. As the chemicals in the liquid move down the column‚ they separate depending on their physical and chemical attributes‚ such as speed and weight. To easily picture the process‚ the example will pertain to a paper chromatography process in which the liquid is moving over the paper‚ separating

Separaration of Powers The purpose of this paper is to discuss the Separation of Powers doctrine built into the Constitution. Discussion will cover the origins of the doctrine‚ the factors that made it attractive to the founding fathers‚ and the question of its usefulness in modern America. Political theorists as far back as Aristotle had discussed the merits of various forms of government. The point had been made over and over again that to have all governmental authority vested in a single

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

Types of conflict in ‘A Separation’ 1) Simin - Internal Conflict – Wants to leave Iran with her daughter. - Tries to divorce Nader Termeh - She creates conflict in her daughter’s life by forcing her to choose a parent. - Class conflict - Conflict with Azam (Raziehs Sister) who blames Simin for her sister’s predicament - Conflict with society – ostracised as a women seeking divorce in Iran (Theocratic) - Questioning/Doubting her abilities as a mother 2) Nader - Torn between his ‘love’ for Simin

Discussion Using the Thin Layer Chromatography experiment‚ caffeine was found to be the most polar due to the fact that it stayed closer to the stationary phase. Caffeine contains four amine groups that are extremely polar as a result of the hydrogen bond and amide functional group. Acetaminophen was found to be the second most polar analgesic drug tested. Acetaminophen contains a polar alcohol group on one side and amide group on the other but also includes non-polar functional groups that consisted
