When Mg3N2 reacts with H2O, it undergoes a chemical reaction to produce different compounds. The reaction can be represented by the following equation:

Mg3N2 + H2O -> Mg(OH)2 + NH3

In this reaction, Mg3N2 (magnesium nitride) reacts with H2O (water) to form Mg(OH)2 (magnesium hydroxide) and NH3 (ammonia).

To balance this equation, we need to ensure that the number of atoms of each element is the same on both sides. Here's how we can balance it:

1. Balance the magnesium (Mg) atoms: On the left side, we have 3 Mg atoms, while on the right side, we have 1 Mg atom in Mg(OH)2. To balance this, we need to put a coefficient of 3 in front of Mg(OH)2:

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

2. Balance the nitrogen (N) atoms: On the left side, we have 2 N atoms in Mg3N2, and on the right side, we have 1 N atom in NH3. To balance this, we don't need to make any changes as the number of N atoms is already equal on both sides.

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

3. Balance the hydrogen (H) atoms: On the left side, we have 2 H atoms in H2O, while on the right side, we have 6 H atoms in 3 Mg(OH)2 and 3 H atoms in NH3. To balance this, we need to put a coefficient of 3 in front of H2O:

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

Now, the equation is balanced with coefficients of 1 in front of Mg3N2, 3 in front of H2O, 3 in front of Mg(OH)2, and 1 in front of NH3.

Answer:

1Mg₃N₂ + 6H₂O

Explanation:  

Hydrolysis: In the presence of excess water and at moderate temperatures, magnesium nitride undergoes hydrolysis, reacting with water to form magnesium hydroxide and ammonia:

Mg₃N₂ + 6H₂O → 3Mg(OH)₂ + 2NH₃

This reaction is exothermic, meaning it releases heat.
