Q:I have lost water pressure in my 1983 home. My pipes are made of copper and I have not had any problems until this morning. I am thinking that one of the pipes has cracked due to the cold temps last night but I just don‘t know where to start! I need some help with troubleshooting before I call a plumber. Can someone please help?For more details.I lose water pressure in the far back bathroom. I have no water filling up the toilet AT ALL. When I turn on the faucet, I lose pressure on the other side of the house. Basically, the further back I go in the house, the less pressure I get. This happen OVERNIGHT. That toilet, by the way, is right next to an outside brick wall where there is an ouside faucet. Thinking there is a link between the two. NO.I did not leave my water dripping last night but I did have insulation on the outside faucet.: Haha, that is the best title I have ever seen! hahah, funny guy! Anywho, you should definitely do it, more experience the better.

Q:i want to electroplate a metal thing with copper, which, as we all know, can be done by any high school chemistry student -- put the metallic object to be electroplated and a chunk of copper in a strong CuSO4 (aq) bath and apply atleast (3V was it?) of electric current. be sure to have the chunk of copper as cathode and the metal object as anode.the problem is that this method of electroplating doesn't really leave a good finish on the object to be electroplated. i don't care if i need to sand and polish the thing, but the copper accumulation is REALLY UNEVEN... so how do i get a considerably good finish?: I think it depends on what you need it for, how thick you need the Cu layer. But yeah you can use a solution mixture of sulfuric acid and hydrochloric acid diluted in DI water. Electronics grade Cu is also available in order to have a high purity Cu layer.(Note this might be really thin for what you are doing) Check Technic Inc.from RI they sell brighteners and other chemicals that will help the uniformity. If you are using a big chunk of copper, use a thin metal sheet that is larger than your item, a factor of 10 fold would be the safest bet. also putting your electrode in the center of the Cu would help a bit, though the resistance should be quite low... so that shouldn't be terrible.

Q:How we can differentiate Copper-Nickel alloy pipes and Normal Copper pipes in Appearance?: Visually? Don't think you can for new ones. Maybe with age or corrosion you can.

Q:Does anyone know how much 2 copper dimes would be worth?: Type Numismatics in your search box. This should take you to coin collectors and you can research in most any of the sites. Never heard of a copper dime but wished I had one.

Q:If you prefer another material besides plastic or copper, please feel free to respond. Thanks.: Copper has proven itself over time- to be the BEST choice for pipes & plumbing fixtures. Plastic ALWAYS cracks- eventually, and the other metals just tend to corrode too quickly... Sure- copper is expensive... -But, like anything ELSE, you GET what you pay for... And Copper will outlive YOUR decision to choose it. :)

Q:I want to safely get the moss off my roof and keep it off. I hear about copper strips or wire, but also read that once the copper turns green, it loses its effectiveness. is this true? Also don't want to use chemicals because of plants on the ground, any suggestions? I do have a pressure washer and thought of using it, low pressure and making sure not to spray against the shingles.: The green is copper oxide and yes it still works when green. Zinc is for cathodic corrosion resistance not for anti-biotic properties, it's the copper that kills the moss. The green copper should actually work better as it's leaching more copper. You don't want the zinc, it would keep the copper from leaching out. You put the copper strips as high up on the roof as possible ie.: along the ridge, so that the copper leaches down over the entire roof. It stops working when the copper is all gone but that should several hundred years from now.

Q:Assuming the copper in the penny is Copper-68 and using the knowledge of radioactive emissions. Write a complete balanced nuclear equation that will demonstrate the transmutation of the copper when is undergoes:A. Alpha emissionB. Beta emissionC. Gamma emission: Copper-68 is most likely going to decay by beta decay, but a metastable nuclear isomer exists that may be able to decay by either gamma emission or internal conversion. Alpha emission is improbable or impossible, but it's possible to specify a formula even if the probability is zero. The alpha process would be Cu-68 -> Ni-68 + He-4 + The beta process would be: Cu-68 -> Zn-68 + e- + -v(e) That is, copper-68 turns to zinc 68, one electron, and one electron-antineutrino. The gamma emission (for the nuclear isomer) would be: Cu-68 -> Cu-68 + gamma The internal conversion (for the nuclear isomer) would be: Cu-68 + e- -> Cu- + e- (The initial e- would be a ground state electron, while the resulting e- would be a high-energy electron.) The notation above isn't quite standard, due to limitations of plain text. Check my references to see standard notation. Finally, what does a penny have to do with it? Given the short half-life of Cu-68, it would be pretty difficult to get enough of it to make anything out of it that was big enough to see.

Q:how much would a 2 ft copper pipe cost?: Depends on the diameter. Places like Lowes have short pieces in a bin next to the full lengths.

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.
