Answer:
To decompose the Mg3N and release ammonium gas
Explanation:
Distilled water is the pure state of water, without mixing with other substances and microorganisms. It is obtained through the distillation process. Even though it is clean water, it is not suitable for consumption, however it can have several other applications, such as being added to the crucible after ignition of the magnesium metal, because it allows the decomposition of Mg3N and release of ammonium gas, avoiding the emergence of explosions.
