Reaction of Magnesium Nitride with Water
When magnesium nitride reacts with water, it undergoes hydrolysis to produce magnesium hydroxide and ammonia gas.
Mg3N2 + 6H2O → 3Mg(OH)2 + 2NH3
Explanation
- Magnesium nitride has the chemical formula Mg3N2, which means it contains three magnesium atoms and two nitrogen atoms in each molecule.
- When it is reacted with water, the nitrogen atoms in the magnesium nitride molecules react with water molecules to form ammonia gas (NH3).
- The magnesium atoms in the magnesium nitride react with the hydroxide ions (OH-) from the water molecules to form magnesium hydroxide (Mg(OH)2).
- The balanced chemical equation for the reaction is Mg3N2 + 6H2O → 3Mg(OH)2 + 2NH3.
Conclusion
Thus, one mole of magnesium nitride on reaction with an excess of water gives two moles of ammonia and three moles of magnesium hydroxide. The correct answer is option C, which states that two moles of ammonia are produced.
