How does ammonia react with a solution of Cu²⁺?

Ammonia on reacting with Cu²⁺ acts as a Lewis base and donates its electron pair to the metal ion and forms a linkage with the metal ion.

Here, colour of Cu²⁺ is blue whereas the colour of [Cu(NH₃)₄]²⁺ is deep blue.

Why is N₂ less reactive at room temperature?

Mention the conditions required to maximise the yield of ammonia.

What is the covalence of nitrogen in N₂O₅ ?
