Explanation:
Oxidation is any chemical reaction that involves the moving of electrons. ... When iron reacts with oxygen it forms a chemical called rust because it has been oxidized (the iron has lost some electrons) and the oxygen has been reduced (the oxygen has gained some electrons).
eg.
C + O2 ------ CO2
Carbon reacts with oxygen and undergoes oxidation.....
oxidation reaction is exothermic reaction...
