The color of the unheated copper is brown, or golden brown. The formula for that would be Cu.
Yes, copper sulfate is considered a pure substance because it has a definite and uniform composition of copper, sulfur, and oxygen in a fixed ratio. It can be represented by a chemical formula (CuSO4) and is not a mixture of different substances.
The green color on copper when it oxidizes in the air is a physical change, not a chemical change. The process is primarily due to the formation of a layer of copper oxide on the surface of the copper, which alters the appearance without changing the chemical composition of the copper itself.
Copper (II) oxide, also known as cupric oxide, has the chemical formula CuO. It is a black solid and is commonly used as a pigment in ceramics and glass.
It depends ~ if it's copper(I), then the formula is Cu2CO3, but if it's copper(II), the the formula is CuCO3
Copper wire is a pure substance, as it is made entirely of copper atoms.
Yes, copper sulfate is considered a pure substance because it has a definite and uniform composition of copper, sulfur, and oxygen in a fixed ratio. It can be represented by a chemical formula (CuSO4) and is not a mixture of different substances.
Copper carbonate is a chemical substance, also called Cupric carbonate. The molecular formula is CuCO3. Copper carbonate decomposes at high temperatures, giving off carbon dioxide and leaving copper(II) oxide.

The darks substance is copper oxide, formed when the copper reacts with atmospheric oxygen.
Yes, copper is an element, which is a pure substance.
