Vedclass · Answer

(B) In the extraction of iron,haematite $(Fe_2O_3)$ is reduced to pig iron in a blast furnace using coke and limestone. This is a correct match.Copper matte is a mixture of $Cu_2S$ and $FeS$,and its conversion to $Cu$ involves Bessemerization (self-reduction),but the option is often considered incomplete or less accurate compared to the blast furnace process for iron.Galena $(PbS)$ is converted to $PbO$ by roasting (not calcination).Red bauxite is purified by the Bayer process,and $Al$ is obtained by Hall-Heroult electrolytic reduction,but the process sequence is distinct.

List-$I$	List-$II$
$(i)$ Explosive	$(A)$ $NaN_3$
$(ii)$ Artificial gem	$(B)$ $Fe_3O_4$
$(iii)$ Self reduction	$(C)$ $Sn$
$(iv)$ Magnetic material	$(D)$ $Al_2O_3$
	$(E)$ $Pb(N_3)_2$
	$(F)$ $Fe_2O_3$
	$(G)$ $Cu$
	$(H)$ $SiC$

$A$. $PbS \rightarrow PbO$	$p$. roasting
$B$. $CaCO_3 \rightarrow CaO$	$q$. calcination
$C$. $ZnS \rightarrow Zn$	$r$. Carbon reduction
