It should be a "pure" substance, but its really an alloy.
If it is all copper, it is a pure substance.
Copper wire is pure copper.

It should be a "pure" substance, but its really an alloy.
it is substance
Its a Mechanical Mixture.Why? Because its just out of a metal. Also its made out of a outer ring of the toonie is 99% nickle. The center is 92% copper, 6% aluminium, and 2% nickle... Thats why its a Mechanical Mixture.
Are there different parts that are visible. No so homogenous

Copper wire is homogeneous.
copper is an ELEMENT therefore it is not a heterogeneous OR homogeneous mixture.
Yes, it is a homogenous mixture.
When you place copper wire in a silver nitrate solution, your result should be a heterogeneous mixture.

It's an element.

Copper is on the Periodic Table, anything on the periodic table is an element so copper wire is made from an element.
