...Copper (, ) is a chemical element with the symbol Cu () and atomic number 29.It is a ductile metal with very high thermal and electrical conductivity. Pure copper is rather soft and malleable and a freshly-exposed surface has a pinkish or peachy color. It is used as a thermal conductor, an electrical conductor, a building material, and a constituent of various metal alloys. Read full entry

Copper ?!?!?!?!?!?
I just replaced the copper
wiring in my home and have
about 30 feet left over , how
much should I get by going to
a recycling company or scrap
yard ?????????

Look in the phone book for metal recycling companies. Ask them how much per pound copper is getting and if you have to have the insulation stripped before they'll accept it. It may be better to just hang onto the wiring because there will always be some electrical project you'll need it for in the future. |

What is the difference between I am doing a plumbing repair,
and on the Grainger website I
can get the supplies I need in
copper and wrot copper. I just
want to make sure, before I
purchase the wrot copper, that
it works just as well as
regular copper, and can be
sweat just like regular
copper. Is there any
difference between the 2 that
I need to know?

just in the manufacturing end, either type will work fine |

What causes copper to be I preformed an experiment in
chemistry in which we placed a
piece of copper into HCL and
left it there for a week. When
I went back to look at the
experiment, the copper had
been oxidized. What caused
this? And what is the chemical
equation? I know that hydrogen
will not oxidize copper due to
their placement on the
activity series.
Thank you for your help.

IF any copper oxide was formed while the copper was setting in hydrochloric acid, the copper oxide would dissolve. Copper may not dissolve in hydrochloric acid. (see 1) But copper oxide is a basicoxideand it would dissolve in hydrochloric acid. Per this reaction: CuO + 2 HCl = CuCl2 + H2O |
