Vedclass · Answer

(B) Let us analyze the given options:$A$: Calamine $(ZnCO_3)$ and Siderite $(FeCO_3)$ are indeed carbonates.$B$: Argentite is $Ag_2S$ (a sulphide ore),not an oxide. Cuprite is $Cu_2O$ (an oxide ore). Since Argentite is a sulphide,this statement is incorrect.$C$: Zinc blende $(ZnS)$ and Pyrites $(FeS_2)$ are indeed sulphides.$D$: Malachite $(CuCO_3 \cdot Cu(OH)_2)$ and Azurite $(2CuCO_3 \cdot Cu(OH)_2)$ are indeed copper ores.Therefore,the incorrect statement is $B$.
