When a metal reacts with oxygen, a metal oxide forms. The general equation for this reaction is: metal + oxygen → metal oxide. Rust is a form of iron oxide and it forms slowly when iron is exposed to air. Iron can be transformed to steel (an alloy), which is more resistant to rust.

Answer:
When metal reacts with O2
Mg + O2 =MgO. Mg- Magnesium O2- Oxygen
when non-metal reacts with O2
C + O2 = CO2. C- Carbon O2 - oxygen.
when metals react with H2O
2Mg(s) + 2H2O(l) = 2M OH(aq) + H2(g)
when non-metal reacts with H2O
Non-metals does not react with water.
Sulphur + water = No Reaction.
