                                    Strong acids contain molecules 
                                    that come apart (IONISE) in 
                                    water.  Hydrogen particles, called

  Order of Reactivity
                                    A more reactive metal takes the place of a less reactive metal in a 
  Chemists react metals with        compound
  acid to put the metals in 
  order of reactivity.  
  How do you think this could 
  be done from the picture?  
  What would the reactivity 
  of these metals be?
