it is magnesium sulphate that should answer your question.
Magnesium Sulphide
magnesium sulphide (MgS)
S + O2 --> SO2 sulfer dioxide
antimony
A white powdery substance is formed.It is Magnesium oxide which is formed by the reaction of magnesium with oxygen.
The solid formed is magnesium oxide.The gas formed is carbon dioxide.
magnesium sulphide
magnesium sulphide (MgS)
magnesium sulfate
S + O2 --> SO2 sulfer dioxide
I think that it is probably magnesium sulphate.
The salt formed when magnesium reacts with nitric acid is magnesium nitrate.
Magnesium Oxide is a compound which is formed when Oxygen from the air reacts with Magnesium to form a White powder known as Magnesium oxide ~ Hope this helped
Magnesium Oxide Reacts With Sulfur Trioxide added: Magnesium sulfate is formed: MgO + SO3 --> MgSO4
magnesium phosphate?
Magnesium reacts with oxygen to form magnesium oxide (MgO).
sulfur which then forms magnesium sulfide
Magnesium hydride, MgH2
