A colourless inorganic salt (A) decompos...

A colourless inorganic salt `(A)` decomposes completely at about `250^@ C` to give only two products `(B)` and `( C)`, leaving no residue. The oxide `( C)` is a liquid at room temperature and neutral to litmus paper while the gas `(B)` is a neutral oxide. White phosphorous burns in excess of `(B)` to produce a strong white dehydrating agent. Write balanced equations for the reactions involved in this process.
