100% pure metal is actually quite difficult (some may argue impossible) to achieve. Copper pipe can be produced from one of 5 alloys under the "Standard Specification for Seamless Copper Pipe". They range from being 99.9% pure copper to containing a maximum of 0.04% phosphorus. While in a laboratory it would not be considered pure, in everyday life. . . copper pipe is basically all copper.
Neither, copper is a pure element.
No, copper chloride is a pure substance.
No, copper chloride is a pure substance.
copper is an ELEMENT therefore it is not a heterogeneous OR homogeneous mixture.
No. Copper used in wiring would not qualify as laboratory-grade (pure). It would be far too expensive to manufacture and would not improve the conductivity enough to make a difference. Some copper wire is even plated. Laboratory-grade (pure) copper is a single substance, the element copper.
Copper is a pure substance.
Yes, copper is an element, which is a pure substance.
Pure:CuSO4(H2O)5
It should be a "pure" substance, but its really an alloy.
Copper metal is an element and thus a pure substance.

Copper sulfate is a pure substance.
Copper(I) chloride is a pure substance.
no
Either gold or copper on their own would be pure substances. But if you have them together it's a mixture, not a pure substance.
