Introduction - The Five Classes of Chemical Reactions

 
  
 
I.  COMBINATION REACTIONS:  METALS REACT WITH NON-METALS TO FORM IONIC COMPOUNDS.
  

Sodium reacts with chlorine to form sodium chloride.

 

Aluminum reacts with bromine to form aluminum bromide.

 
 

Magnesium burns in air to produce magnesium oxide.
