The equation Mg3N2 + 6H2O -> 3Mg(OH)2 + 2NH3

  1. Detailed information about the equation Mg3N2 + 6H2O -> 3Mg(OH)2 + 2NH3

    • The above equation describes the reaction process between magnesium nitride (Mg3N2) and water (H2O) to form magnesium hydroxide (Mg(OH)2) and ammonia (NH3).
    • According to the reaction ratio, one molecule of magnesium nitride needs to react with six molecules of water to form three molecules of magnesium hydroxide and two molecules of ammonia.

  2. Reaction conditions

    • This reaction usually occurs under normal temperature and pressure conditions.
    • Magnesium nitride needs to be directly exposed to water for the reaction to take place.

  3. Reaction process

    • When magnesium nitride comes into contact with water, it immediately reacts, producing magnesium hydroxide and ammonia.
    • During this process, the nitride ions from magnesium nitride are replaced by hydroxide ions from water, forming magnesium hydroxide.
    • The hydrogen ions from water combine with the nitride to form ammonia.

  4. Occurring phenomena

    • When the reaction occurs, we will see the formation of a white solid substance of magnesium hydroxide and smell the distinctive odor of ammonia.
    • At the same time, there may be a release of heat as this reaction is an exothermic reaction (a reaction that releases heat).
