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?: this website has a list of quite a number of different suggestions. You can spray or brush chemicals on your copper surface. Generally you should be a well ventilated area. Don't forget that you can do the last suggestion. Washes of actual acrylic paint can indeed work. Just make sure you don't paint it solid, then it could be any material. In addition there are already made up patina solutions for copper which you can buy. As you probably would have to order them I don't know whether your time constraint is such, that this is not an option.

Q: I burned copper (wool) [ 49.34 g] for a certain amount of time, and its color changed; (copper oxide formed)but the mass is still 49.34 g!! Why?: In all liklihood you did NOT burn the copper, you only burned the surface of the copper. In this case, the copper itself probably weighed a good deal more than the amount converted to oxide, so the mass change was unnoticeable. To really see the difference, you would need temps in excess of 3000 degrees and an oxygen-rich environment or some other method for fully oxidizing the copper. same is true for the steel wool except that steel will tend to flake away as it oxidizes (rather than forming a protective coat). Fully convert the steel wool and you will similarly see the mass change as oxygen is absorbed.

Q: We heated purified copper powder in a crucible over a hot plate (while continuosly stirring) the result, the powder turned black.What can be the purpose of this experiment? Is this correct: To determine whether there is a chemical reaction when Copper powder is heated?: Copper forms a black oxide, CuO, but because it is relatively unreactive, it takes a lot of heat to make it oxidize. (It also forms a red oxide, Cu?O, but not under the oxidizing conditions of the atmosphere.)

Q: I am poor and need the moneys. Theres are lots of pipes in the old hospice that I may acess. Is God approving in these instance to feedsmy kid?: i love AEM n Injen, yes.if u do like the sounddoes give u abit more hp (5 is max) noif there're alot of floaded areas near you.cuz CAI is locate under you car n if it sucks in waterur engine is gone

Q: I‘m writing up my A2 physics coursework and i understand the concept of eddy currents and that it‘s because copper is a better conductor but i good explanation of how a better conductor leads to stronger eddy currents would be highly appricieated.Thankyou so much in advance !! :D: Magnet Falling Through Copper Tube

Q: I think taurus makes a solid copper hand gun bullet and maybe one or two other companies do as well. The reviews are great.: Why are they needed, a copper jacket is all that is required. Sounds like a good sales pitch.

Q: A 10-g piece of copper is to be formed into a wire of radius 1.0 mm at a temperature of 50 degrees C. What is the resistance of this wire? (Hint: you will need to look up the density of copper.) If a potential of 12 V is put across the wire, what is the drift velocity? (Assume one electron per copper atom): I’ll provide you with a “road map” to answer this interesting question. Variables: R = resistance ρ = resistivity = 1.68E-8 (copper at 20?) L = length A = area D = density = 8.96 g/cm^3 = 8960 kg/m^3 V = volume R = radius of wire = 0.001 m m = mass wire = 0.010 kg ?T = temperature change (?C) α = temperature co-efficient = 0.0068 (copper) I = current (A) n = electron density = 6E28 m-3 (for copper) q = charge on electron = 1.6E-19 C Equations needed: R = ρL / A D = m / V ?R / R? = α?T I = nAvq I = V / R The length of 10 g of copper of radius 1.0 mm is calculated by: D = m / V = m / (π r? L) L = m / D π r? = (number crunching !) The resistance of 0.357 m of wire is determined by: R = ρL / A = (number crunching !) Adjusting for new temperature: ?R / R? = α?T ?R = α?T x R? = (number crunching !) Hence: R = (think & number crunching !) Drift velocity formula: I = nAvq I = V / R V / R = nAvq v = V / (nAqR) = (number crunching !) This should help. Good luck

Q: In an older home, I have pipes that are about 30 years old, should I be planning to replace them. The pipes are accessable in the basement, in the suspended ceiling. I recently had a small hole in a horizontal section, near the elbow from the upstairs toilet. Is this from water turbulence or from toilet cleaners that were used?: copper pipe should last forever.

Q: I did this lab called stoichiometry using copper and there is a question that I don't understand. They ask what ions are you removing when you wash the precipitate copper? I dont expect the answer b/c obviously u guy don't know the lab, but can you guy explain what they mean by asking that question. Thanks: You started the experiment with a soluble copper salt in solution, probably copper sulfate or copper chloride. You added a chemical which interacted with the copper salt, allowing the copper to become metallic copper or an insoluble copper salt, which then precipitates. The remaining liquid in the precipitate contains another soluble salt. What is it? To figure this out, what did you start with? What did you add? If you now have an insoluble copper salt or metallic copper, the ions you get in the rinse are the other components you used in the reaction.

Q: I cut out the bad section, Only about 3. Is there a way to replace the 3 bad copper piece with PVC pipe? And if I can, How do I connect the 2 open copper ends to the new pvc replacement pipe. So the original pipe looked like this _______. I took out 3 in the middle so now it looks like this _____ _____. So asking if I can put a pvc pipe in that gap and connect it water tight with the copper? Thanks for your help. I am sick of doing this!!! Thanks: Go to Ace hardware, and ask for a slip on compression fitting, named a Shark bite fitting. It will slip over the copper, and you can install a replacement piece of copper pipe, without soldering. You will need two of these fittings, and a piece of copper pipe. Slip it all together, and you are good to go. It should take less than a minute to do it, and it is all copper. Good luck!
