Respuesta :

 2Fe  +O2 =  2FeO

this reaction belong  a  combustion reaction

a combustion reaction  involve a  reaction   between  a  substance   and oxygen.  the reaction above is a  combustion reaction because  the reaction  involve the reaction of  iron (Fe)  with oxygen  and release  large amount of energy and  therefore 

2Fe + O2 =2FeO 
  is a combustion reaction
