Dissolve it in water
Burn magnesium in an atmosphere of oxygen.
Magnesium oxide will react with water to form Magnesium Hydroxide.Magnesium Hydroxide will not reat further with water
No, magnesium is its natural state while magnesium oxide is formed magnesium heated in oxygen or air
positive 2
2Mg + O2 --> MgO Oxygen oxidizes the Mg to Mg2+, which in turn reacts with oxygen to form MgO
