copper comes from beneath the earth
Yes, ethanol can react with copper. Ethanol can form complexes with copper, such as copper(II) ethoxide, when they come into contact. This reaction can be influenced by factors such as temperature, concentration, and presence of other chemicals.
Copper sulphate crystals form when a hot saturated solution of copper sulphate is cooled down. As the solution cools, the solubility of copper sulphate decreases, causing the excess copper sulphate to come out of the solution and form crystals.
Copper and Cobalt come to mind immediately.
This reaction is an example of a displacement reaction, where aluminum displaces copper from copper (II) nitrate solution to form aluminum nitrate and copper metal. The copper metal appearing on top of the solution is a result of this displacement reaction.
Yes, copper can come in different colors due to tarnishing or alloying with other metals. Freshly exposed copper has a reddish-brown color, but it can develop a patina over time that ranges from green to blue to black depending on the environmental conditions. Copper alloys like brass and bronze can also have a range of colors based on their composition.

Copper does not come from human beings. Copper is a naturally occurring element found in the Earth's crust and is extracted from ores through mining processes. Human beings do not produce copper in their bodies.
Chile
A lot of coins are made of copper, thus the term.
Copper wire sent for recycling is remelted and rerefined. It becomes a new copper product one of which might be new copper wire.
Yes because bronze is made of copper so copper was around before bronze
metel
depends. Where did it come from
Copper has been used for thousands of years. Ancient civilizations used copper. The old kingdom of Egypt had copper tools, jewelry, and pots. This was 7,000 to 5,000 years ago.
