Q:How to renovate copper tubes: How to renovate copper tubes

Q:Hey thanks guys for posting your replys. I was revising AS Chemistry and i was asked to write the configuration of copper. I wrote it as, 1S^2, 2S 2, 2PX 2, PY2 PZ2, 3S2 3P6 4S 2, 3D 9. Which is incorrect. He said this because 1 shell is half filled to give more stability, but which one. My lecturer didn't tell me why. And i checked on the internet but i cant find a valid source some one Help me plz. i need to know by Friday as i have a mock exam on Monday. Thanks people!!!: Yes RoboHondaMonkey is right, sometimes certain elemental isotopes will favor having the outer d shells filled and lose electron in the more unfavorable ones.

Q:So say we needed to conserve copper so what could we do to do so and still make stuff that involves copper.: tax it or ban it

Q:I bought an antique copper hip flask from Portebello market (London), when I washed it out with water loads of grime came out. Is it safe to drink hard liquor from it or will I get some sort of copper poisining? I've washed it out with boiling water and fairy antibacterial washing up liquid, what would you recomend I do? thanks in advance :D xx: Is the flask lined with another metal other than copper, IF NOT, don't use it as you could get cooper poisoning...yes I am serious....If it is lined then use a vinegar,soap &water solution and let it set for a few hours to a day, then rinse it out and clean well, repeat if necessary,if possible use a bottle brush to help get inside.... Be CAREFUL if the flask is not lined, adding liquor (whiskey)is similar to adding bleach to it and drinking it as the alcohol will have an adverse affect on the copper. IF needed contact a copper smith. ntact PAUL REVERE COOKWARE as they use a lot of copper in their products for advice.

Q:A copper pipe has an inside diameter of 3.00cm and an outside diameter of 5.00cm. What is the resistance of 10.0m of this pipe?copper‘s resistivity 1.72 x 10^-8I can‘t seem to solve this problem. I‘ve tried to do the RpL/A for both the diameter inside and outside then subtract it, but it still isn‘t the correct answer. Please help me with this! Thank you! 10 pts for the best answer!!!!: no usually it uses the same oil as the the engine. Except for a 2 stroke, which has oil in the transmission. Automotive oil will break down faster in a motorcycle, because it goes through the trans. That why they make motorcycle oil. I feel synthetic cures that issue. Have used mobile one in my bike for years

Q:I have a small leak under the bath at the hot water copper pipe. It is small but I do not like to leaveit as in first floor flat. A plummer came and said he had hoped he had fixed it and that it was verydifficult to get at. However it is still a small leak. Would the bath have to be taken out to fix it orsomething big like that, which I would not want of course. The bathroom basin is very near the bathso that makes it harder to get at the pipe maybe. Am I going to have a big problem here. Any plummers to advise me please. Most grateful. Thanks so much. I live in Shefford Bedfordshire. Is there a brillant plummer there or joke a very slim one who is agile and can slide under a difficultarea e.g. my difficult to get at pipes under bath.: did you install it right? did you disconnect the battery to reset the comp?

Q:The water pipe was under a slab of a home in Northern Florida.: Shark bites are for amatures. Use the compression fitting, you'll be fine.

Q:copper slag is waste product coming out of copper industries.my question is how much harmfull is it when we inhale it?: Copper slag is the waste product of copper ore smelting. It is normally processed to produce usable grit for sandblasting of metal surfaces. It is extensively used in shipbuilding, ship repair, and other steel fabrication industries. The copper slag is produced by pumping the molten slag against a jet of water. The slag cools into small granules. Copper slag is relatively inert and quite hard but not very brittle so that it is a good material for sandblasting. In fact it could even be recycled for reuse as much as three times before it is becomes too fine to use. While it is true that harmful metals come along with copper ore, most of these metals go along with the product copper concentrate in the smelting so that there is relatively a very small amount of these metals left in the slag. This plus the fact that water is used in the production of the slag, which is tantamount to washing, makes the slag quite safer than using silica sand in the sandblasting of metal surfaces. Nevertheless protection against inhalation of the dust is still needed as, like any other dust, it may cause respiratory problems.

Q:my science teacher said i may have found real gold so i have to find copper to scratch a lil gold off if i am able to then its real...so i need to look for something made of copper: In 1793 to 1837 a US penny was 100% copper. 1837–1857 bronze (95% copper, 5% tin and zinc) 1857–1864 87.5% copper, 12.5% nickel (also known as NS-12) 1864–1942 bronze (95% copper, 5% tin and zinc) 1943 - - - - - - - - zinc-coated steel 1944–1946 brass (95% copper, 5% zinc) 1946–1962 bronze (95% copper, 5% tin and zinc) 1962–1982 brass (95% copper, 5% zinc) 1982– present 97.5% zinc core, 2.5% copper plating The copper scratch gold test bit is not very definitive, copper will scratch another copper. Most,if not all fake gold is made with copper. To find out if it is made of gold, touch it with a glass stopper which has been wetted with nitric acid. If it is pure gold nothing will happen; if not, the solution will become blue from the formation of nitrate of copper. Or ask any good jeweler.
