Q: I‘m an art student working on a sculpture piece whose main component is copper piping. I need to oxidize it quickly and evenly. Most of the suggestions I‘ve found either take months or need to be submerged, and that simply isn‘t an option. Any suggestions?: chlorine. soak it in water that has a lot of chlorine in it.

Q: I am doing a project for year 9 science, and am a little confused to why copper is such a good conductor. I have tried researching, but dont understand the information I have found.Thankyouxoxox: Copper is a good conductor because electrons can flow through it easly. Simple as that. The reason why it is a worse conductor cold, is because electrons slow down in cold temperatures. If you heat an object up, such as the material tungston (inside your tv). It moves electrons so fast it shoots them off of the material and at your tv screen which creates an image. Hents why your old color tube tv needed to take a few seconds to warm up before the picture was crisp.

Q: My friend with a plumbing business says I need to re-pipe my house.It was built in 79‘ and is copper.Our guest bathroom tub faucet spits out some rusty looking water when we turn it on, even if it was used just a few days ago.I think there must be some galvinized pipes in that tub plumbing configuration that needs replacing,NOT the entire houses pipes.I‘d love to here from some others on this matter.Thanks in advance Bill B.: LOL, I hope ur friend didn't offer a good price to go w/ his good advice. U r thinking correctly, the faucet actually screws onto a piece of steel pipe, that connects the faucet to the faucet assy. (assembly includes faucet, hot, cold and the long piece that runs up to the shower head, if urs has a shower head) a piece of steel pipe, usually around 5 to 61/2 inches, runs from the assembly, through the wall and extends 4 inches or so out. the faucet is actually hollow inside, until the last inch or so and that part is threaded to screw over this piece of pipe. It probably isn't galvanized, but is black pipe or some other non rust resistant, steel. Just wrap a towel or something soft, around the faucet and unscrew it from this pipe, from the tub side, using a pipewrench. then unscrew the now exposed pipe, take it to the hardware store and buy a new, galvanized piece the same length and some pipe dope. look into the hole it came out of, to make sure there isn't any obstruction, put dope on the threads and stick the pipe back through the hole and tighten down. put dope on the outer threads and screw the faucet back over it and u have a finished product that doesn't have that little bit of rust run out every time u turn it on. should be under ten bucks for the pipe and dope and take longer to go to the store than to make the actual repair. good luck, lol and a toast to good friends.

Q: I had a solution of salt water. Cathode was aluminum and the anode was a nickel plated coin. The aluminum was plated in a dark metal which might be nickel. There was also an insoluable orange substance produced at the anode. Was that copper from the nickel plated copper coin? What were the reactions going on here?: Copper atoms go into solution at the anode: Cu ---> Cu2+ + 2e- Copper ions from the solution deposit on the cathode as copper atoms i.e. copper metal: Cu2+ + 2e- ---> Cu So no, you didn't create elemental copper, you just transferred it from the anode to the cathode.

Q: I did a lab using post and pre 1982 penniesPre 1982 pennies were made of copperPost 1982 pennies are made of zincI have to answer the following questions:1. How would copper react in concentrated hydrochloric acid? zinc?2. How would the copper penny react when cut, exposing the inner metal? zinc? Include description of copper and zinc.: 1. How would copper react in concentrated hydrochloric acid? zinc? copper gets its tarnish removed, & gets quite shiny Zinc reacts with the acid producing H2 gas, & the zinc totally disappears into solution 2. How would the copper penny react when cut, exposing the inner metal? zinc? Include description of copper and zinc. the cut allows the acid to contact the zinc, bypassing the rest of the protective copper coating the outer copper cover to the penny gets its tarnish removed, & gets quite shiny Zinc reacts with the acid producing H2 gas, & the zinc totally disappears into solution you will be left with a hollow penny copper coating

Q: How many atoms of phosphorus are in 5.00 mol of copper(II) phosphate?: copper II phosphate is Cu3(PO4)2 Each mole of copper II phos. contains 2 moles of phos. atoms so 5 x 2 = 10 moles of phos. atoms 10 x 6.022 x10^23 = 6.022 x10^24 atoms of phos.

Q: If 150mL of .055M copper(II) chloride solution reacts, how many mL of .100M silver nitrate is needed to exactly react with it?We went over this topic in class today but I just don't understand how to do this problem: So first, since you have the volume and molarity for the copper chloride solute, you find the moles for copper chloride. I will be using n to symbolize moles. Remember that the equation for Molarity is Molarity=number of moles of solute divided by the Volume of solution. So your first step would be solving for moles of the copper chloride. That would look like the following: .055M= n/150mL of copper chloride By multiplying 150mL times .055M, you would get 8.25moles. Next, you plug the moles into the Molarity equation again, except now you are solving for the volume of silver nitrate. That would look like the following: .100M=8.25moles divided by the Volume of silver nitrate You solve for volume by dividing 8.25 by .100M to get 82.5. This means that it takes 82.5 mL of silver nitrate to react with the copper chloride. Hope this helps!

Q: I recently installed a water softener and had the plumber up the water pressure to compensate for loss of pressure thru the water softener, it is now at 70 psi (the regulator outside the house was adjusted) - I am paranoid, is this OK for copper piping?? Should I have it turned back to 55 which is where it started at ?: your best bet would be to look for a used and fuctional transmission on another Trans Am. And that transmission may go out fast, your car may become a hungry tyrant for tranny repairs.
