how much copper is in copper wire
No. Copper wire is a solid
No.. Copper wire isn't
No, copper wire is not magnetic.
Copper wire sent for recycling is remelted and rerefined. It becomes a new copper product one of which might be new copper wire.
When copper wire is dipped in a solution of magnesium chloride, no significant reaction occurs because copper is less reactive than magnesium. The magnesium ions in the solution do not displace copper from its metallic state. As a result, the copper wire remains unchanged in appearance and composition. However, if the solution were to contain a more reactive metal, such as zinc, a displacement reaction could occur.
When a copper wire is heated in a Bunsen burner flame, the copper's color changes to become a glowing red. It won't be restored to its original appearance after cooling. Instead, it becomes a black material called copper (II) oxide, which is 79.9% copper and 20.1% oxygen (was 100% copper before it was burned). This chemical change occurred as the oxygen in the air combined with the copper during the heating process.
If you mean a bare copper wire, that is the "ground" wire.
Yes, if it is not an insulated wire. If it is bare copper it is always ground. But the hot and neutral wire are also copper, they are just insulated.
To separate powdered charcoal from a mixture containing copper oxide, just add water. Charcoal is considered quite a bit less dense than water and one set of tables gives the density as circa 400 kg.m-3 . Copper oxide is much more dense than water or charcoal. So the copper oxide will sink to the bottom and the charcoal will float to the top of the water. This can now be decanted and filtered leaving the charcoal on the filter paper which can be dried and to leave charcoal. Then with a separate filtration, the copper oxide and traces of water can be filtered and then dried.
To refine copper wire scrap, you need professional tools and equipment such as copper stripper which is used for removing insulation from copper wire.
