# Mg+O2 is a combination reaction or Oxidation reaction?? And how to differentiate in these two reaction.

Dear Student

2 Mg + O2$\to$MgO is both types.

Oxidative reaction-  Oxidation reaction is a reaction that involves gain of oxygen or a loss of hydrogen. When a substance gains oxygen or loses hydrogen during a reaction, it is oxidized.
Example  2 Mg + O2$\to$MgO

Combination reaction- A combination reaction is a reaction where two or more elements or compounds combine to form a single compound.
​Example  2 Mg + O2$\to$MgO​
