Ozone :: essays research papers fc
OzoneTriatomic oxygen, O3, is most commonly known as ozone. It has a plangency structure, and can be drawn in two different ship canalO=O-O-O=OIt is a bluish, explosive gas at get on temperature, and has a boiling pointof -119C. It has a melting point of -193C, and is a blue liquid. Itscritical temperature and pressure atomic number 18 -12.1C and 53.8 atm, respectively. Ithas a winning odor in concentrations of less than 2 ppm, and is irritating andinjurious in higher concentrations. The density of ozone gas is 2.144 g/L, andthe density of ozone as a liquid is 1.614 g/mL. It is extremely unstable, andsolutions containing ozone explode upon warming. It is found in alterproportions on Earth, but it is about 0.05 ppm at sea level.Ozone absorbs harmful ultraviolet illumination radiation in the upper atmosphere, andprotects humans from skin cancer. But ozone is as well the main ingredient of smog,and causes sober health effect and forest and make damage in the loweratmosphere. Oz one is formed through the chemical reaction of volatile organiccompounds and nitrogen dioxide, in the atmosphere, in the presence of sunlight.This reaction is called a photochemical reaction, because sunlight is required.The product is known as smog. The disreputable brownish color of smog is due tonitrogen dioxide of the mixture. Increased temperature bump around the reaction,which is why ozone conditions are worse in the summer. It is an oxidant,meaning it takes electrons away from some other molecules, and disrupts keystructures in cells by starting chain reactions.Ozone is a serious national problem. Half of the largest urban field of honors inthe United States exceed the ozone standards. The thrash regions in the USinclude California and the Texas Gulf coast, and the northeast and the Chicago-Milwaukee area during the summer. The ozone condition varies from year to year,as the temperature and weather fluctuate. This fluctuation also occursthroughout the day, as emission s from morning traffic builds up, the levels rise.Ozone emissions come from many things, such as automobiles, gas stations, powerplants, dry cleaners, paint shops, chemical manufacturing pants, oil refineries,and other business that release volatile organic compounds.The health effects of ozone are chest pain, coughing, wheezing, lung andnasal congestion, labored breathing, sore throat, nausea, rapid breathing, andeye and wind irritation. The symptoms occur when the levels of ozone are onlyslightly higher than the legal standard. animate in San Diego during myelementary school year, I personally felt the effects of ozone the tightness ofthe chest, wheezing, and labored breathing on certain hot, humid days.
