When ammonia is passed over heated CuO, it is oxidised to:?
Answers
Answer:
When gaseous ammonia is passed over solid copper(II)oxide at high temperatures, nitrogen gas is formed.
Explanation:
Reaction
2NH3(g)+3CuO(s)=N2(g)+3Cu(s)+3H2O(g)
Also This N2 gas is not pure as it would be in the heating of NaN3 like compounds. (VERY IMPORTANT FOR NEET)
Answer:
Nitrogen (N₂) gas is formed when ammonia (NH₃) passes over heated Cu or copper(II) oxide.
Explanation:
Copper (Cu), Nitrogen(N₂), and water vapor is the result of a reaction in which ammonia is passed over a heated copper(II) oxide.
As we know, Ammonia is a strong reducing agent, and in this reaction, copper oxide is acting as an oxidizing agent due to which ammonia gets oxidized to nitrogen (N₂) and it results in the reduction of CuO into the free metal.
The reaction is provided below:
