Mg(s)+O2(g)-->MgO(s)
MgO is magnesium oxide.
oxidation reduction.

You would think that the Mg just combined with the Oxygen in the air wouldn't you! Probably because of the word 'burn', however, although it does combine with the 'O', it also combines with the Nitrogen in the air forming Mg3N2.
This can be carried on step further and a little water put on the 'ash', might just get a little ammonia smell.

2Mg + O2 = 2MgO (magnesium Oxide)

burning is a combustion reaction. a combustion reaction yields co2 + h20.
