Chemistry Research Paper 3 pages long

Research how much salt a large northern city, such as New York City, or Chicago, uses on its streets in a typical winter. Which salt is most commonly used? What environmental problems result from this use of salt? What substitutes for salt are being used to melt ice and snow? Why are they not used exclusively? Your response must be a 3 page typed paper. You must use 12 point font, double spacing and one inch margins. You must use 3 different sources and create a bibliography in the MLA style. You must include at least one picture or graph. If more pictures are used, the paper length must be adjusted accordingly.
