Synthesis Reactions---Help

:rofl: I am having trouble deciding two different synthesis equations for an experiment done at school.
The expermient consisted of heating magnesium and then adding a few drops of H2O. Reactions where Nirtogen, Magnesium, and H2O. The products where Ammonia, Magmesium Nitride and Magnesium Oxide.

My two equations (as I thought of it) are:
1) Mg + H2O -----> NH3
2) Mg + "X" ------>Mg"X"

I now need to figure out X....My first thought was that the X element consists of something from the air which gives me O2. Another possibility is H2.
