They include copper I and copper II sulphide (Cu2S and CuS).
Another, very common compound is copper sulphate, CuSO4
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.
NO!!! Because if it was a mixture it would NOT be pure.
It should be a "pure" substance, but its really an alloy.
Copper wire is a pure substance, as it is made entirely of copper atoms.
