The solution of sodium metal in liquid ammonia is a strong reducing agent due to the presence of...

The commercial method of preparation of potassium by reduction of molten $KCl$ with metallic sodium at $850 ^\circ C$ is based on the fact that:

The golden yellow colour associated with $NaCl$ in a Bunsen flame can be explained on the basis of

$A$ metal $M$ reacts with $N_2$ to form a compound $A$ $(M_3N)$. Heating $A$ at a high temperature gives back $M$,and passing $A$ through $H_2O$ results in the evolution of gas $B$. Gas $B$ turns $CuSO_4$ solution blue. What are $A$ and $B$ respectively?

The magnetic behaviour of $Li_2O$,$Na_2O_2$ and $KO_2$,respectively,are

In the Solvay ammonia process,why does sodium bicarbonate precipitate?
