The copper wire glows red. Once it cools...the copper reacts with the air to produce copper(II) oxide. This is shown by the black tarnish on the copper wire.
Anhydrous copper sulfate is white powder, heating makes no difference.
Organic material.
Although US one-cent coins (pennies) were once mostly copper, today they are 97.5% zinc with a copper plating. Copper nails are rare due to the metal's malleable nature, but zinc nails can be plated with copper as are pennies. Brass is an alloy of copper and zinc, and is widely used.

Copper is refined in a smelter. Then once raw copper is obtained the final purification is via electroplating.
yes.It comes from wood.
