Vedclass · Answer

(B) $1$. Calamine is $ZnCO_3$ and siderite is $FeCO_3$. Both are carbonate ores. (Correct)$2$. Argentite is $Ag_2S$ (sulphide) and cuprite is $Cu_2O$ (oxide). Since argentite is a sulphide ore,the statement that both are oxide ores is incorrect. (Incorrect)$3$. Zinc blende is $ZnS$ and iron pyrites is $FeS_2$. Both are sulphide ores. (Correct)$4$. Malachite is $Cu(OH)_2 \cdot CuCO_3$ and azurite is $Cu(OH)_2 \cdot 2CuCO_3$. Both are copper ores. (Correct)Therefore,the incorrect statement is $B$.

List-$I$ (Ores)	List-$II$ (Composition)
$a$. Haematite	$i$. $Fe_{3}O_{4}$
$b$. Magnetite	$ii$. $ZnCO_{3}$
$c$. Calamine	$iii$. $Fe_{2}O_{3}$
$d$. Kaolinite	$iv$. $[Al_{2}(OH)_{4}Si_{2}O_{5}]$
