text: Some examples of exothermic processes are:
  * Combustion of fuels such as wood, coal and oil/petroleum
  * The thermite reaction
  * The reaction of alkali metals and other highly electropositive metals with water
  * Condensation of rain from water vapor
  * Mixing water and strong acids or strong bases
  * The reaction of acids and bases
  * Dehydration of carbohydrates by sulfuric acid
  * The setting of cement and concrete
  * Some polymerization reactions such as the setting of epoxy resin
  * The reaction of most metals with halogens or oxygen
  * Nuclear fusion in hydrogen bombs and in stellar cores (to iron) 
  * Nuclear fission of heavy elements
  * The reaction between zinc and hydrochloric acid
  * Respiration (breaking down of glucose to release energy in cells)
