Answer:

Magnesium metals are not affected by water at room temperature. Magnesium generally is a slow-reacting element, but reactivity increases with oxygen levels. Furthermore, magnesium reacts with water vapor to magnesium hydroxide and hydrogen gas:

Mg (s) + 2H2O(g) -> Mg(OH)2(aq) + H2(g)

Magnesium fires cannot be extinguished by water. Magnesium continues to burn after oxygen is depleted. It than reacts with nitrogen from air to form magnesium nitride (Mg3N2). When attempts are made to extinguish magnesium fires with water, magnesium aggressively reacts with hydrogen gas. To prevent any damage, a magnesium fire must be covered in sand.

An example of a magnesium compound is magnesium phosphide (Mg3P2), an odorous, grey solid. When this compound comes in contact with water or moist air, it is decomposed and phosphine (PH3) is formed.

Hope it might help you .
