yes.

No. Copper wire is made of the element copper. Tungsten wire is made of the element tungsten. Copper wire is made to conduct electricity. Tungsten wire is made for the filament in light bulbs as tungsten does not melt under even very high temperatures.
copper is an ELEMENT therefore it is not a heterogeneous OR homogeneous mixture.
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.)
When copper is pulled into thin wires, it is called copper wire drawing. This process involves passing the copper through a series of decreasing diameter dies to gradually reduce its diameter and form a thin wire.
Plastic, copper wire, silicon chips, and various other materials.

No, portable cell phone chargers will not harm your phone. I've used wall chargers and cigarette lighter chargers with phones and never had any problems related to them.
how much copper is in copper wire
No. Copper wire is a solid
Copper wire itself is not waterproof, but it is highly resistant to moisture and corrosion. Bare copper can still oxidize over time when exposed to water, which may affect performance in the long run. For outdoor or wet environments, manufacturers use insulation like PVC or XLPE to protect the wire. Choosing the right copper wire for waterproof electrical applications and outdoor installations ensures safety and durability. If you're planning to buy, always look for high-quality insulated wires from trusted suppliers like RK Copper & Alloy LLP, as proper coating and material quality play a key role in preventing damage and ensuring long-term performance.
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.
If you mean a bare copper wire, that is the "ground" wire.
aluminum foil and copper wire--but how does it block a cell phone's connection??-_-
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 refine copper wire scrap, you need professional tools and equipment such as copper stripper which is used for removing insulation from copper wire.
