Reactivity & Displacement Reactions (C7)

• metal + oxygen -> ?

  and what is this reaction?

  metal oxide, this is rusting
• metal + water -> ?

  metal hydroxide + hydrogen
• metal + steam -> ?

  metal oxide + hydrogen
• what process is: alkali + metal -> salt


  neutralisation
• metal carbonate + acid -> ?

  salt + water + carbon dioxide
• precautions when reacting metal w/ acid (3 marks)

  not using reactive metal & calcium in acid bcs it will cause violent reaction or explosion ; not using concentrated acid bcs acid is corrosive ; use small amount of meta/acid bcs hydrogen gas may explode
• metal + acid -> ?

  salt + hydrogen
• can aluminium be displaced by zinc?

  no
• is potassium or sodium more reactive?

  potassium is most reactive
• zinc sulphate + iron -> ?

  no reaction
• copper chloride + calcium -> ?

  calcium chloride + copper
• sulphuric acid + lithium ->

  lithium sulphate + hydrogen
• copper carbonate + nitric acid ->

  copper nitrate + water + carbon dioxide
• iron + oxygen ->

  iron oxide
