Oxides

• CHEMICAL PROPERTIES OF OXYGEN

  
  

  Reaction with Metals:

  
  

  a.Metal + O2 = Metal Oxides

  Examples: Na + O2 = Na2O

  Mg + O2 = MgO

  
  

  Metal Oxide + H20 = Metal Hydroxide

  Examples: Na2O + H20= NaOH

  MgO + H20= Mg (OH)2 (aq)

  
  

  b.Non-metal + O2 = Non-metal dioxide

  Examples: C + O2 = Carbon dioxide

  S + O2 = Sulfur dioxide

  N + O2= Nitrogen dioxide

  
  

  Non-metal + H20 = Non-metal hydroxide

  Examples: NO2 + H2O
