Abstract In the following project we are discussing about distillation. The operation of the distillation is employed for the purification of liquids from non-volatile impurities. The liquid is heated to the vapor phase and then is collected and recondensed to give back the pure liquid .The non-volatile impurities are left behind in the flask. Here our main focus will be at the fractional distillation. It is the process in which we separate the different components of a mixture on the basis of the

Should teenagers have a tattoo? Having prevailed in the world for thousands years‚ nowadays‚ tattoos have been known in every corner of the world (Lawrence‚ 1999). The Food and Drug Administration estimated that 45 millions people in the United States have at least a tattoo (Israel‚ 2011) and then 17% of them regrets getting tattoos (Schulz‚ 2011) due to its health effects and the discrimination against it. Thus‚ in our opinion‚ teenagers should not be allowed to have a tattoo.

haloalkanes and haloarenes with various types of reactions. (iv) Use stereochemistry as a tool for understanding the reaction mechanism. (v) Describe common polyhalogen compounds. INTRODUCTION The replacement of hydrogen atom(s) in a hydrocarbon‚ aliphatic or aromatic‚ by halogen atom(s) results in the formation of alkyl halide (haloalkane) and aryl halide (haloarene)‚ respectively. Many halogen containing organic compounds occur in nature and some of these are clinically useful. These classes

chemistry‚ the organic compounds which are made up of carbon and hydrogen are called hydrocarbons. They can be gases as‚ propane‚ they can be liquids‚ for example‚ benzene‚ or they can be low-melting solids and waxes‚ for example‚ polystyrene. There are four classifications of hydrocarbons; saturated hydrocarbons or alkanes‚ unsaturated hydrocarbons or alkenes and alkynes‚ cycloalkanes‚ and aromatic hydrocarbons or arenes. The different between these groups is in the bond types between the carbons

THE BIOSPHERE The environment (biosphere) extends to about 20 km from the bottom of the ocean to the highest point in the atmosphere at which life can survive without manmade protective devices. Biosphere contains about 1.8 million known species. The essential requisites of life for all life forms (light‚ heat‚ water‚ food‚ and habitats) are supplied by the biosphere. Biosphere is very complex and large‚ so it is divided into smaller units (ecosystems). Each ecosystem consists of two parts: biotic
