traditionally an atmospheric phenomenon where dust‚ smoke and other dry particles obscure the clarity of the sky. The World Meteorological Organization manual of codes includes a classification of horizontal obscuration into categories of fog‚ ice fog‚ steam fog‚mist‚ haze‚ smoke‚ volcanic ash‚ dust‚ sand and snow.[1] Sources for haze particles include farming (ploughing in dry weather)‚ traffic‚ industry‚ and wildfires.

Formation of an Alkene by Alcohol Dehydration Lab Report Balanced Chemical Equation for the Main Reaction Mechanism The acid-catalyzed dehydration of secondary and tertiary alcohols involves non-isolable carbocation intermediaries. In the first step of the of the reaction mechanism below‚ a phosphoric acid catalyst adds a proton to the oxygen atom of the alcohol to form an oxonium ion. The OH is converted to a better leaving group as the positive charge on the oxygen weakens the carbon-oxygen

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

0°c and melting point is 100°c. The traditional process used in distillation is vacuum distillation basically the boiling of water at less than atmospheric pressure and as a result a much lower temperature than normal. Distillation is a very expensive process‚ so people use eco distillations. Eco distillation is a process called Solar distillation. Solar desalination is a technique to desalinate water using solar energy. Distillation processes can also occur in the nature. The formation of sea ice

The relationship between the locals and the Europeans was very important in Southeast Asia during the time of the sixteenth to eighteenth centuries. The local rulers that were established had maintained a grip on their territory and had to be consulted before setting up trading posts. Any Europeans that ventured down to this region must have been prepared for what they would be encountering on its shores. Whether it was the Dutch from the Netherlands‚ the English country traders‚ the Portuguese or
