Release of Oxides

Describe, using equations, examples of chemical reactions which release sulfur dioxide and chemical reactions which release oxides of nitrogen



  • In a metal sulfide smelter, the metal sulfide and oxygen react to produce a metal oxide and sulfur dioxide, such as in the case of zinc sulfide smelting:
  • In the combustion of fossil fuels, the sulfur contained in sulfur compounds and oxygen react to produce sulfur dioxide:
  • Due to the very high local temperatures produced by lightening strikes and combustion, nitrogen and oxygen in the atmosphere react to produce nitric oxide:
  • Nitric oxide and oxygen in the atmosphere react slowly to produce nitrogen dioxide:
