Vedclass · Answer

(B) The incorrect statement is $B$. Calamine is $ZnCO_3$ and siderite is $FeCO_3$,which are both carbonates. Argentite is $Ag_2S$ (sulphide) and cuprite is $Cu_2O$ (oxide),so the statement that both are oxides is incorrect. Zinc blende is $ZnS$ and pyrites (iron pyrites) is $FeS_2$,which are both sulphides. Malachite is $Cu(OH)_2 \cdot CuCO_3$ and azurite is $2CuCO_3 \cdot Cu(OH)_2$,which are both ores of copper.
