The incorrect statement is :
Options
A.Calamine and Siderite are carbonates
B.Argentite and cuprites are oxides
C.Zn blende and iron pyrites are sulphides
D.Malachite and azurite are ores of Cu
Solution
Argentite (Ag2S) is a sulphide while cuprite (ruby copper) is an oxide Cu2O).
Calamine -ZnCO3, Siderite - FeCO3,
Zn-blende-ZnS. Iron pyrites FeSh2, Malachite-CuCO3. Cu(OH)2, Azurite-2CuCO. Cu(OH2)
Calamine -ZnCO3, Siderite - FeCO3,
Zn-blende-ZnS. Iron pyrites FeSh2, Malachite-CuCO3. Cu(OH)2, Azurite-2CuCO. Cu(OH2)
