  Reduction

  Gained
• Metals react with oxygen to produce metal oxides
• Acid + Metal Oxide --> Metal salt + water

  Acid + Metal hydroxide --> Metal salt + water

  Acid + Metal carbonate --> Metal salt + Carbon dioxide + water
• Oxidation and reduction are redox reactions
• 2Cu + O2 --> 2 CuO

  Copper has been oxidised as oxygen is being added to it
• ZnO + C --> Zn + CO

  Zinc oxide is being reduced as oxygen is being reduced
