Bauxite isthe principleore ofaluminium. Itcannot be reducedwith carbon to give thecorrespondingmetalbut whenheatedat2273K, it gives compound (X) which upontreatment withwatergives a gas (Y) which isthe majorconstituent of natural gas.Identify(X) and (Y) andexplainthe reactionsinvolvedtherein.

Answer»

Solution :Bauxineishydratedalumina` (A_ 2 l _ 2O_ 3.2 H_2 O )`. Onheating strongly with carbon,it gives alumininum carbide(X).
` "" underset("Bauxite")(Al_2O_3.2H_2O)overset(1473K)to underset("ALUMINA")(Al_2O_3) +2 H_2O `
` 2 Al_2O_3+ C overset (2273K) tounderset("Aluminium carbide (X)") (Al_4 C_3) +6CO`
`underset("Aluminium carbide (X)")(Al_4C_3 ) +12 H_2 Oto4Al (OH)_ 3+underset(" (CONSTITUENT ofnaturalgas )")underset ("METHANE (Y)") (3CH_ 4)`
