INTERCHAPTER S Synthetic Polymers The formation of nylon by a condensation polymerization reaction at the interface of water and hexane‚ two immiscible solvents. The lower water layer contains the compound hexanedioyl dichloride‚ Cl C(CH2)4C O O Cl hexanedioyl dichloride The reaction produces nylon and HCl(aq). The polymer forms at the interface between the two solutions and is drawn out as a continuous strand. University Science Books‚ ©2011. All rights reserved. www.uscibooks.com

Polymers are a part of our every day life and without them around‚ this world would be very‚ very different‚ if not impossible to live in. However‚ most people do not even know what a polymer is‚ or just how widespread they are around us. Polymers are formed from hydrocarbons‚ hydrocarbon derivatives‚ or sometimes from silicon. They are the basis not only for numerous natural materials‚ but also for most of the synthetic plastics that one encounters in their lives. Polymers consist of extremely large

“Synthetic” By Rica Pepito (For Math 10 Lesson: Synthetic Division) People nowadays are craving for things they like but some cannot afford and therefore would prefer the synthetic ones rather than the original items. Although pricing is a big deal‚ quality is a huge liability. This Louis Vuitton bag is so nice but bought one fourth of the original price and the store it was bought from does not have legal rights to sell those nor the item itself couldn’t last a week in terms of durability.

Introduction to Use of statistics in daily life:- Statistics deal with frequency distribution. It is used to compare twoor more frequency distribution taken from different population to see if there are any differences between them. The statistics uses the following measures for the comparisson. They are mean‚ median and mode. Mean is the average of all the observations. Median is the middle most value of the observations and mode has the maximum frequencies. Let us see the use of statistics
