The Correct Option is D
Solution and Explanation
In this question, we need to identify which compound among the given options is known as malachite.
Malachite is a copper carbonate hydroxide mineral with the chemical formula \(CuCO_3.Cu(OH)_2\). This is a common copper mineral and is known for its bright green color, which is often used as a gemstone and in ornamental carvings.
- \(CuFeS_2\): This is Chalcopyrite, a copper iron sulfide mineral.
- \(Cu(OH)_2\): This is Copper(II) hydroxide, a blue solid substance used as a pigment.
- \(Fe_3O_4\): This is Magnetite, an iron oxide mineral, and it is not related to copper.
- \(CuCO_3.Cu(OH)_2\): This is Malachite, a green mineral consisting of copper carbonate hydroxide.
Therefore, the correct answer is \(CuCO_3.Cu(OH)_2\), which is the formula for malachite.
To conclude, malachite is characterized by its distinctive green color and is represented by the chemical formula \(CuCO_3.Cu(OH)_2\). This distinguishes it from other minerals and compounds listed in the options.
