How do you get powdered charcoal from a mixture of copper oxide and powdered charcoal?
To obtain powdered charcoal from a mixture of copper oxide and powdered charcoal, you can use a reduction reaction. Heat the mixture in a furnace or with a suitable heat source, as copper oxide will react with the charcoal (carbon) to form copper and carbon dioxide. The copper will be produced as a metal, leaving behind the powdered charcoal. After cooling, you can separate the unreacted charcoal from the copper.

Composition of copper wire in generators?
how much copper is in copper wire
Is copper wire a plasma?
No. Copper wire is a solid
Is copper wire waterproof?
No.. Copper wire isn't
Is a copper wire magnetic?
No, copper wire is not magnetic.
What happen if copper wire dip in solution of magnesium chloride?
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.
Dose recycled copper wire be come new copper wire?
Copper wire sent for recycling is remelted and rerefined. It becomes a new copper product one of which might be new copper wire.
What is the evidence that indicates that both physical and chemical changes occur when a copper wire is heated in a Bunsen burner flame?
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.
Why does an electrical circuit have a copper wire?
If you mean a bare copper wire, that is the "ground" wire.
How do you separate powdered charcoal from a mixture of copper oxide?
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.
Is a copper wire a 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.
