• Iron (III) oxide + carbon --> iron + carbon dioxide 

  2Fe2O3 + 3C --> 4Fe + 3CO2
• carbon + oxygen --> carbon dioxide

  C + O --> CO2
• carbon dioxide + carbon --> carbon monoxide

  CO2 + C --> 2CO
• iron (III) oxide + carbon monoxide --> iron + carbon dioxide 


  Fe2O3 + 3CO --> 2Fe + 3CO2
• Group 1 to 4 --> most reactive is down (reactivity decreases from group to group until g4)
• group 5 to 7 --> most reactive is up (most reactive g7)
• Copper blue

  Nickel green

  Iron (II) green turning to brown

  Iron (III) orange/brown
• carbon monoxide

  from incomplete combustion of hydrocarbons
• sulfur dioxide

  from buring fossil fuels
• oxides of nitrogen

  burning fossil fuels
• rusting takes place when there is water
