What are the products formed when ammonia reacts with excess chlorine?
When ammonia reacts with excess chlorine the following reaction takes place.
$$NH_3+3Cl_2\xrightarrow \ NCl_3+3HCl$$
An aqueous solution of ammonia contains :
Sodium dissolved in ammonia has blue colour due to:
A metal $$'M'$$ reacts with nitrogen gas to give $$'M_3N'$$. $$'M_3N'$$ on heating at high temperature gives back $$'M'$$ and on reaction with water produces gas $$'B'$$. Gas $$'B'$$ reacts with aqueous solutions of $$CuSO_4$$ to form a deep blue compound. $$'M'$$ and $$'B'$$ respectively are:
Nitration of which among the following compounds yields cyclonite?
Explain why NH3 is basic while BiH3 is only feebly basic.
Match the column I with column II and mark the appropriate choice. Column I Column II (A) Laughing gas (i) Hydrazoic acid (B) Anhydride of $$HNO_{3}$$ (ii) Nitrous oxide (C) Anhydride of $$HPO_{3}$$ (iii) Nitrogen pentoxide (D) Acid hydride of nitrogen (iv) Phosphorus pentoxide
Ammonia is a Lewis base. It forms complexes with cations. Which one of the following cations does not form complex with ammonia?
Why does $$NH_{3}$$ act as a Lewis base?
Give reasons for the following: Ammonia acts as a ligand.
Write the balanced equation for the reaction between ammonia and sulphuric acid.
