 ==Properties==
+Chlorine is usually found combined in nature because of its reactivity. It is ready to use commercially by passing electricity through a water solution of sodium chloride or through molten sodium chloride. Chlorine gases are made up of diatomic molecules, as the formula C12. The gas can be smelled in the air at a 3 parts per million(ppm), and it is irritating to the nose, mouth, and lungs. Thus, it cause throat irritation at 15 ppm, coughing at 30 ppm, and cause deadly effect a few deep breaths at 1,000 ppm.
+Chlorine gas is easy to liquify in water, and occur chemical reaction, that produce hydrochloric acid (HCl) and hypochlorous acid (HOCl), plus some unreacted C12. That is called chlorine water and it is kiing germs in water or to bleach papaers and fabrics.
+Chlorinated hydocarbons-hydrocarbons have have had some of their hydrogen atoms replaced by chlorne atoms. A variety of chlorinated hydrocarbons have been used as insecticides. One of the earliest to be used was DDT, dichlorodiphenyl-trichloroethane. However, it caused serious enviromental problems,  it is not use as much as before in the United States.
+Other chlorinated hydrocarbons are used as pesticides in the farms, but all of these compounds are very stable so they are becoming a serious problem.
