What happens when magnesium is burnt in a jar if nitrogen and the product is warmed after moistened with water (give the equation of the reaction)
3Mg + N2 ==> Mg3N2
Mg3N2 + 6HOH ==> 3Mg(OH)2 + 2NH3
Well, if you really want to see things heat up, let's take a look!
When magnesium (Mg) is burned in a jar with nitrogen (N₂), it produces magnesium nitride (Mg₃N₂). The equation for this reaction is:
3Mg + N₂ → Mg₃N₂
Now, things get even more interesting when the product, Mg₃N₂, is warmed after being moistened with water. This causes the formation of ammonia gas (NH₃) and magnesium hydroxide (Mg(OH)₂). The equation for this reaction is:
Mg₃N₂ + 6H₂O → 3Mg(OH)₂ + 2NH₃
So, in the end, you'll have ammonia gas and magnesium hydroxide, which might make for a rather strange combination. Just remember, safety first, and don't try this at home!
When magnesium (Mg) is burnt in a jar filled with nitrogen (N₂) gas, it undergoes a reaction known as combustion where it reacts with oxygen (O₂) from the air. The equation for this combustion reaction is:
2Mg + N₂ → 2MgN
The product formed is magnesium nitride (MgN).
If this product is then warmed and moistened with water (H₂O), it reacts further to form magnesium hydroxide (Mg(OH)₂). The equation for this reaction is:
MgN + 2H₂O → Mg(OH)₂ + NH₃
The product formed is magnesium hydroxide (Mg(OH)₂) and ammonia (NH₃).
When magnesium is burnt in a jar containing nitrogen, it reacts with the nitrogen to form magnesium nitride (Mg3N2). The equation for this reaction is:
3 Mg + N2 → Mg3N2
The reaction involves three atoms of magnesium combining with one molecule of nitrogen gas to produce one molecule of magnesium nitride.
If the product, magnesium nitride, is then warmed after being moistened with water, it reacts with water to produce magnesium hydroxide (Mg(OH)2) and ammonia gas (NH3). The equation for this reaction is:
Mg3N2 + 6 H2O → 3 Mg(OH)2 + 2 NH3
In this reaction, the magnesium nitride reacts with water molecules to form three molecules of magnesium hydroxide and two molecules of ammonia.
It is important to note that the reaction between magnesium nitride and water should be conducted with caution, as the evolution of ammonia gas can be toxic and should be carried out in a well-ventilated area.
