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 an ELEMENT therefore it is not a heterogeneous OR homogeneous mixture.
Copper wire is matter that is comprised of only one element: copper. It is a pure substance because it is made up of only one type of atom.
No, its a compound which is 2 or more elements combined. Copper oxide is copper + oxygen which are 2 separate substances.
Copper. The wire is made of elemntal copper not a chemical compound. (Note the copper used may sometimes be alloyed with another metal or occasionally be a solid solution of small amounts of oxide in the pure metal. This improves the durability and handling characteristics of the wire.)
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.
Copper wire is a pure substance, as it is made entirely of copper atoms.
copper is an ELEMENT therefore it is not a heterogeneous OR homogeneous mixture.
It should be a "pure" substance, but its really an alloy.
It should be a "pure" substance, but its really an alloy.
Copper wire is made of the element copper. Copper is a pure substance, not a compound, because it is made up of only one type of atom.
Copper is a pure substance.
Yes, copper is an element, which is a pure substance.
Copper used in wiring would not qualify as laboratory-grade (pure). It would be too expensive to manufacture.
Copper metal is an element and thus a pure substance.
