Consider the following reactions

$2\,XS\, + \,3{O_2}\,\xrightarrow{\Delta }\,2XO\, + \,2S{O_2}$

$2\,XO\, + \,XS\,\xrightarrow{\Delta }\,3'X'\, + \,S{O_2}$

Then $'X'$ can not be

$Hg$

$Pb$

$Zn$

None

Solution

$Zn$ is extracted from its sulphide ore by roasting followed by carbon reduction $Hg,\,Pb$ and $Cu$ are extracted by self reduction from their sulphide ores.

Consider the following metallurgical processes

$(i)$ Heating impure metal with $CO$ and distilling the resulting volatile carbonyl (boiling point $43\,^oC$) and finally decomposing at $150\,^oC$ to $200\,^oC$ to get the pure metal.

$(ii)$ Heating the sulphide ore in air until a part is converted to oxide and then further heating in the absence of air to let the oxide react with unchanged sulphide.

$(iii)$ Electrolysing the molten electrolyte containing approximately equal amounts of the metal chloride and $CaCl_2$ to obtain the metal.

The process used for obtaining sodium, nickel and copper are, respectively,
