On treatment with cold water, an element (A) reacted quietly liberating a colourless, odourless gas (B), and a solution (C). Lithium reacted with (B) yielding a solid product (D) which, effervesced with water to give a strongly basic solution (F). When carbon dioxide was bubbled through solution (C) an initial white precipitate (G) was formed, but this re-dissolved, forming solution (H) when more carbon dioxide was added. Precipitate (G) effervesced when moistened with concentrated hydrochloric acid, and gave a deep red colouration to a Bunsen burner flame. When (G) was heated with carbon at 1000°C a caustic white compound (I) was formed, which when heated with carbon at 1000° C gave a solid (J) of some commercial importance. Name the substances (A) to (J) and give balanced chemical equations for each of the reactions.
