how do we get the element copper and what is it usually used for?

Question

this is my chemistry homework again and you guys seem like boffins and i really am not unfortuatley so thanx!!! ;)

whoa thank you!

i'm liking the pennies from heaven thing
hahaha

wow 'ben b' sure knows his stuff

Answer 1

They dig it out of Earth as copper mostly, its used for pipes, wire, coating pennies, etc.

You really should do your own homework. I guess asking me is sort of like looking it up. They used to ask me in school if we would always carry around calculaters to get the answers, in college it turned out, thats exactly what we did. Will you always have bored unemployed people around to answer random questions, maybe so.

Answer 2

Copper is an element, which means it isnt "made", like brass is, (trumpets, etc) which is an "alloy", made by melting tin and copper together. Its just "is" (like tin) and is found in the ground, attatched to rock, which has to be smashed up to get it out. It can be little grains, within the rock. This metal/rock mixture, is called an "ore". (if its iron in the rock, its iron ore, if its copper in the rock, its copper ore).
So copper is an "element", and a "metal".
It is used, on its own, to make copper wire, because copper is an excellent conductor of electricity. (much better, than if it were steel wire).
The uses of copper wire, include this broadband connection, and all telephone wires.
It is also used as an alloy....adding tin, to make "brass". Trumpets, trombones, things that poke fires, etc.
It is one of the major (im a jeweller!) components of all 9ct gold jewellery, as nine carat gold, is 37.5% gold, 10% silver, 5% other metal, and about 47% copper! Thats right, 9ct gold is only a third pure gold! So copper is important to jewellery production.
Copper wire, is also fundamental to an electric motor, it is wound around in a coil, and effectes a magnet, (spinning the motor), to create electricity.

Answer 3

It is mined from ore, sometimes it occurrs pure but usually has to be refined from a copper-containing mineral. Copper ore is typically found near gold mines or is a by-product of refining gold.

Most pennies are copper plated zinc except the old pennies. Take a newer penny and sand it down or cut it in two and you will see the silvery color inside it.

Answer 4

Copper is present in nature combined to other elements. Commercially, the ore from which copper is gotten is copper pyrite (CuS). The ore is roasted in air to combine with atmospheric oxygen and it forms CuO. The Copper II oxide is then reduced using coke. Usually, the copper gotten is impure copper so the copper is purified by electrolysis.

Copper is useful in the following:
1. Manufacture of electrical cables.
2. manufacture of important alloys e.g brass, bronze etc.
3. Manufacture of currency due to their durability and resistance to rust (NOTE: They do rust, but a protective layer of rust forms on the surface which prevents the further exposure of the underlying metal to rust)

Answer 5

copper is mined, from ore, deep unergropund. it originally came from Cornwall England, where it was recognsed as a valuable metal and used for pots pans mirrors and the like; as we developed, metalurgists/alchemists began creating alloys... bronze, gunmetal, brass... copper Cu, doesnt corrode in the normal way. it goes green, this is verdigris, look at any church roof..those green stains on the walls...copper.

google some of the words..and make it look like you at least had a go...

Answer 6

Copper is mined as ore (usually scooped out of very big open pits) and then processed to purify it. The biggest use of copper is for electrical wires and cables. (The smallest use is for charm bracelets that weird people wear to protect themselves from arthritis.)

Answer 7

Copper is used for electrical wiring because it is an excellent conductor of electricity.
It is also used for one cent coins because of its durability.
It is used for water pipes because it is easy to work with.
It is used for cookware because it conducts heat easily.

The bad news is that copper is becoming very expensive and may soon not be used for any of the above.

Answer 8

All copper comes from pennies.

DUH!

Answer 9

pennies from heaven

Answer 10

It comes from ore
