During the year 2013 Etileno was produced by approximately 117 companies from 32 countries. A sample of a hydrocarbon is found to contain 7.48 grams of carbon and 2.52 grams of hydrogen. Thanks Li Zhi - I know the work I've shown doesn't really mirror the work I've done on paper as I can't find the right formatting here on my computer (I wish I was a boss like MaxW hehe). Polymerization (the repetitive joining of many small molecules into larger ones) of ethylene gives polyethylene, a polymer having many uses, particularly in the production of packaging films, wire coatings, and squeeze bottles. So the empirical formula of ethylene glycol is CH 3O; this is the ratio of carbons to hydrogen to oxygen we would find if we tried to determine the composition of the stuff by experiment (i.e. (b) Polymerization Reactions of ethylene: Polymerization of ethene leads to polythenes which are of two types: Low density polyethylene: It is prepared by heating ethene to 463-483 K under the pressure of about 1500 atm. b.
