Science‚ Medicine & Technology – Lecture 2 14th September‚ 2012 Global Warming – Paul Waithe * Differences between climate change & global warming: Global warming is the overall increase in the earth’s temperature. Climate change may be in either direction. For instance; more hurricanes‚ more wind etc. Comprehensive way at looking at weather patterns. * Climate change over the past century is directly linked to global warming. * Global warming could result in the world

The Distillation of an Unknown Compound INTRODUCTION Distillation is the process heating a liquid to form vapor which is then collected when cooled and separated from the original liquid. The purpose of this experiment was to determine the identity of an unknown substance using simple and fractional distillation. Gas chromatography analysis the components of a mixture by separation of the materials by their different boiling points. EXPERIMENTAL The simple distillation apparatus was assembled

Fastest types of ferrent A ferret is a domestic animal which is thought to have originated from Europe. It is thought to be a subspecies of polecat having the same long-shaped body. Ferrets are fast. Some ferrets owners have lost their ferrets when they they thought that they can catch them if they decided to run. When hunting‚ ferrets can take down rabits. They have proven to run very fast especially whe they are startled. They are also able to learn fast. The following breeds of ferrets are fastest

Experiment 16: Fractional Distillation of a Mixture CHM2210L Kelley Paul May 26‚ 2014 Tuesday Session: 50432 Abstract A distillation experiment was performed in attempt to separate two miscible fluids.This experiment used fractional distillation to separate ethanol from the azeotropic mixture of ethanol and water. The initial composition of the solution did not matter because the goal of the experiment was to distill the ethanol-water solution and obtain 95% ethanol in the distilled fraction

Simple and Fractional Distillation Experiment II Stancy Saji‚ 18 September 2014 Purpose Experiment II involved two kinds of distillation techniques: simple and fractional. Simple distillation was done to separate ethyl acetate—which has a usual boiling point of 77º—from a less volatile component‚ while fractional distillation was done to distinguish an ethyl acetate/n-butyl acetate mixture‚ which has boiling points of 77º and 125 º‚ respectively. Results and Discussion As previously stated the

with the use of their background and recently-taught knowledge of the process of distillation‚ which is the technique that is to be applied for the experiment .Knowing ethanol’s‚ which is the chemical present in all alcoholic drinks‚ boiling point as 78%‚ the students are to collect the distilled and separated ethanol into a test tube with a marker indicating that it contains 1.0 mL of the sample from the distillation set-up. The collected distillate is then subjected to a flammability test in order

DISTILLATION- SEPARATION OF A MIXTURE Ronald Ogbu‚ Alex 27th Aug. 2013 Purpose: To separate mixture of acetone and toluene using simple‚ packed and unpacked distillation columns. Results and Discussion: There were three distillation setups: simple‚ unpacked and pack fractional. All three procedures had different distillation apparatus but the unknown mixture was the same for all. The unknown liquid in a 50 ml round bottom flask was heated in a heating mantle such that a

ADJIVON UNIT 1 INTRODUCTION Organic chemistry started as the chemistry of life‚ when that was thought to be different from the chemistry in the laboratory. Then it became the chemistry of carbon compounds‚ especially those found in coal. Now it is both. It is the chemistry of the compounds of carbon along with other elements
