Q: Ive heard alot of things having to deal with copper that im not sure are true or not, what does copper do to the human body. I dont mean if its ingested i mean if its worn, like copper jewelery that claims to relieve joint pain. What does it REALLY do?: Copper is present in all tissues. The average adult body contains about 80 to 120mg of copper, of which most of it is stored in the liver. It is an important catalyst in the formation of the oxygen-carrying molecule hemoglobin. Chronically elevated copper levels in most patients may result from one-sided diets that lack co-factors or copper antagonists, or from the fact that many copper-rich foods are somewhat addictive, such as cocoa / chocolate products, colas, coffee, or tea (copper levels are even higher in tea than in coffee). Copper Toxicity or excessive copper levels have been associated with physical and mental fatigue, depression and other mental problems, schizophrenia, learning disabilities, hyperactivity / ADD, mood swings (sometimes violent, criminal or psychotic behavior) and general behavioral problems, memory and concentration problems, postpartum depression, vascular degeneration, headaches, increased risk of infections, sleep disorders, arthritis, spinal / muscle / joint aches and pains, hemangiomas and several cancers.

Q: was wondering how you did it, they are going to do it to my pipes that are connected to my washer but was wondering how it was done: you clean the ends of the pipes that you are going to sweat together oh heck look at these two sights both give you videos and will give you a little info

Q: Getting rings and they're made of copper alloy. Will it rust?: Not noticeably. Constant rubbing inside and out with normal wear will prevent the rust called patina from showing. If you want to see copper alloy rust, look at a photo of the Statue of Liberty.

Q: I need to know, how copper is made...: Copper is mined something like coal. Neil

Q: Help please!Copper has a cubic close-packed structure. Why does copper wire not break when it is bent? Diamond is used as an abrasive on cutting tools. How do you explain this property in terms of the structure of diamond? List one common property of diamond.Graphite is used as a lubricant. How do you explain this property in terms of the structure of graphite? What is one common property of graphite?Thanks so much! 10 points for the best answer!!: Ions are purely atoms with lacking electrons, constructive value, or better electrons, unfavorable value. A single atom with the two of those circumstances could be stated as an ion. Get 2 or extra of those ions jointly and additionally you get a polyatomic ion. Poly (many), atomic (atoms) ion (charged atom). Ions are atoms, polyatomic ions are purely distinctive ions bonded jointly.

Q: Hello,im investing in silver.But when i look at copper i wonder if that's going to go up like silver did,A while back silver was 3 dollars an oz,gold was 30 a long time ago.Do you think copper will do some thing similar?I mean i have a hard time believing because copper is so widely used,but every one thought investing in gold and silver back then was silly,people who did made a fortune.So whats the probability that copper will go up sharply?I have some copper and i was wondering if i should sell it at the scrap yard or save it,Thanks.: honestly , golds value is loosely based on the price of oil in the middle east so when the price of oil rose so did the value of gold, silver used to have a formula to tell you how much it was valued at by the price of gold. so when gas prices rose so did gold and so forth with silver. copper is a metal that doesn't get its value from anything important enough as the price of crude oil so i doubt its prices will sky rocket but as the american dollars value decreases on the global market it will be valued higher then before so metals retain its value, american currency does not...

Q: Can Plastic pipe(cpvc) be used in place of copper to hook up a tub valve?: yes. pex, and cpvc are for the water supply. pvc is not used as a water supply inside the house. cpvc is the yellowish looking plastic pipe and uses a kinda of orange glue. pex is the flexible plastic pipe and uses crimp rings.

Q: I know gold and silver would be excellent to have and people would recognize their value, but would 1 oz .999 fine copper coins also have value as a form of money: If the economy is completely debased having any tangible valuable commodity would be good. Copper would be among my last choices to hold if I was planning on Weimar-like hyperinflation because the value of copper primarily derives from its industrial uses. When people start building lots of homes with copper pipes, wires, and flashing, copper prices go up. In a situation in which the economy was destroyed as in Weimar, there would be vastly more sellers of copper than buyers because everyone has copper and there would be no economic demand for it (because nobody would be building new houses for instance). The idiots on the Internet who throw around Weimar as a possible future for the US are testament to the failing educational institutions in the US. Weimar hyperinflation grew from the very vengeful Treaty of Versailles that destroyed the German economy. We don't have anything like that happening to the US economy and have much better economic levers than Germany had.

Q: Now they're made of zinc and plated with copper, I think.: This Site Might Help You. RE: When did the US stop making copper pennies? Now they're made of zinc and plated with copper, I think.
