Among the following statements, the incorrect one is:-a)Calamine and ...
Incorrect Statement: Argentite and Cuprite are oxides.
Explanation:
Therefore, the incorrect statement in the given options is "b) Argentite and Cuprite are oxides."
Explanation:
- Calamine and Siderite are carbonates: Calamine, also known as zinc carbonate (ZnCO3), is a carbonate mineral. Siderite, also known as iron carbonate (FeCO3), is another example of a carbonate mineral.
- Zinc blende and Pyrites are sulphides: Zinc blende, also known as sphalerite (ZnS), is a sulfide mineral. Pyrite, also known as iron pyrite or fool's gold (FeS2), is another example of a sulfide mineral.
- Malachite and Azurite are ores of copper: Malachite ([Cu2CO3(OH)2]) and azurite ([Cu3(CO3)2(OH)2]) are examples of copper ores. These minerals contain copper and are often used as a source of copper in industries.
- Argentite and Cuprite are not oxides: Argentite (Ag2S) is a sulfide mineral that contains silver and sulfur. It is not an oxide. Cuprite (Cu2O) is a mineral that contains copper and oxygen. It is an oxide, not a sulfide.
Therefore, the incorrect statement in the given options is "b) Argentite and Cuprite are oxides."
