On treatment with cold water, an element `(A)` reacted quietly liberating a colourless, odourless gas `(B)` and a basic solution `(C )`. Lithium reacted with `(B)` yielding a solid product `(D)` which effervesced with water to give a stongly basic solution `(E)` and gas `(F)`. When `CO_(2)` was bubbled through solution `(C )`, initially a white ppt. `(G)` was formed, but this redissolved forming solution `(H)` when more `CO_(2)` was passed, precipitate `(G)` effervesced when moistened with conc `HCl` and gave a brick red colouration to the bunsen flame. When `(G)` was heated with carbon at `1000^(@)C`, a caustic white compound `(I)` was formed, which when heated with `N_(20` at `1000^(@)C` gave a solid `(J)` of some commercial importance. Identify `(A)` to `(J)` and explain the reactions.
