$Zn$

Vedclass · Answer

(A) The process described is: Ore $\xrightarrow{	ext{Roasting}}$ Metal oxide $\xrightarrow{	ext{Carbon reduction}}$ Metal $M$. $1$. $Zn$ (Zinc) is extracted from its ore (Zinc blende,$ZnS$) by roasting to form $ZnO$,followed by reduction with carbon (coke) to obtain $Zn$. $2$. $Al$ (Aluminum) cannot be extracted by carbon reduction because it is a highly reactive metal; it is extracted by electrolytic reduction. $3$. $Hg$ (Mercury) is extracted from Cinnabar $(HgS)$ by roasting,which directly yields $Hg$ metal (self-reduction),not by carbon reduction. $4$. $Na$ (Sodium) is highly reactive and is extracted by electrolysis of fused $NaCl$. Therefore,the metal that fits the given sequence is $Zn$.
