And when it comes to price gains during the first six-years of a recovery, the current market is second to none. Between March 9, 2009 and March 9, 2015, the S&P 500 has increased by 202%. The only other market run that comes close is the postwar expansion, where the S&P returned 192% in the same time period.
Arctic Ozone Hole. CFCs Chlorofluorocarbon (CFC) is an organic compound that contains carbon, chlorine, and fluorine, produced as a volatile derivative of methane and ethane. A common subclass is the hydrochlorofluorocarbons (HCFCs), which contain hydrogen, as well.Freon is DuPont's brand name for CFCs, HCFCs and related compounds.he most common representative is dichlorodifluoromethane (R-12 or Freon-12). Chlorofluorocarbons (CFCs) are a family of chemical compounds developed back in the 1930's as safe, non-toxic, non-flammable alternative to dangerous substances like ammonia for purposes of refrigeration and spray can propellants.
CFC'S or Chlorofluorocarbons are molecules which demolish the ozone layer. The ozone layer is made up of O3 or ozone molecules these reflect UV rays (harmful ultra violet ligh â¦ t) the CFC'S smash up the O3 into O2 molecules (the type we breathe) these do not reflect UV so we suffer.hlorofluorocarbons (CFCs) are commonly used as the gases used to exchange heat in refrigeration, due to their high volatility. However, when released into the upper atmosphere, their carbon-chlorine bonds are easily broken by solar radiation to release chlorine radicals (unstable chlorine atoms).
