Water is added to the product formed when magnesium is burnt in a jar of nitrogen gas. Write the observation
Answers
Answer: Magnesium when burnt in a jar of nitrogen gas Magnesium Nitride is formed which reacts with water to form Ammonia .
Explanation:3Mg+N2 -------> Mg3N2
Mg3N2+6H2O -------> 3Mg(OH)2 + 2NH3
The observation for the aforementioned reaction is that a pungent smelling gas is evolved as a result of the reaction.
• When magnesium is burnt in a jar of nitrogen gas, magnesium nitride (Mg₃N₂) is formed as a product.
The reaction can be represented as follows :
3Mg + N₂ → Mg₃N₂
• When water is added to magnesium nitride, ammonia gas (NH₃) is evolved, characterized by a pungent odour, along with the formation of magnesium hydroxide (Mg(OH)₂) as a by-product. The reaction can be represented by the following chemical equation :
Mg₃N₂ + 6H₂O → 3Mg(OH)₂ + 2NH₃
• Therefore, a pungent smell is observed on adding water to the product formed on burning magnesium in a jar filled with nitrogen.
