Q:copper carbonate + oxygen (heat) >> ... + carbon dioxide?
copper carbonate + oxygen (heat) copper oxide + carbon dioxide Ans: Copper oxide Cu2O or CuO both are possible.
Q: what's the size of the copper tube?
You should add extra charge to the specific installation location, but it's expensive!
Q:What do I get when I boil copper (II) nitrate?
. If I boil copper (II) nitrate, what do I get in addition to water? Here's the formula to help: Cu(NO3)2 (solid) ------boiling-------> ?? + H2O (liquid) Would it just be copper? Copper nitrate is very stable. Heating copper nitrate will not cause it to decompose in copper metal and NO2.
Q:About the influence of air conditioning copper tube too long?
In theory, the shorter the air conditioning piping, the better. It can reduce the loss, reduce the burden of compressor and reduce the energy consumption. Objective conditions must be extended, piping should also be accurately calculated, and strive for the shortest. The cloth should be straight and bent as much as possible. Bend to be neat, can not flatten the pipe, affecting the flow of fluid. Application of brazing weld interface, full and smooth, not plug welding, trachoma. The pressure test shall be done when welding is completed.In terms of influence. First, the refrigerant must be filled: two is to measure the compressor current, shall not exceed the limit parameters specified by the manufacturer.Please consult the experienced construction staff for specific implementation.
Q:The brass of 42 to 6.4 of each pipe diameter approximately every 100 meters?
The copper pipe has a strong corrosion resistance, and has become the first choice for modern contractors in the installation of plumbing, heating and cooling pipes in all residential commercial premises.
Q:How much is old copper plumbing worth?
It sounds like he removed 3in waste water piping. Copper is worth what the price per pound is right now in your area. I think it is under a dollar per pound right now. But still that 3in pipe is nice scrap. It adds up quick. Unfortunately for you that pipe belongs to the plumber who is taking it out unless specified before the work began.
Q:Plastic, stainless or copper tongue scraper?
Copper Tongue Scraper
Q:i need a copper block, 5mm x 20mm x 20mm, any thoughts?
As kaushal noted, copper wire is usually very pure copper. You can hammer a thick piece of wire until it is about 21 by 21 millimeters, of uniform thickness. Then electroplate, until it is 5 mm in the thinnest part, then trim, grind and polish until the dimensions are close enough for your purpose. The electroplating will further purify the copper if you keep the plating current at one amp or less. A 3 to 5 volt power cube rated one amp or a bit more can be your source of dc current. Dissolve as much pure copper sulphate in distilled or deionized water, as will dissolve, then add a bit of sulfuric acid. You can make your own copper sulphate, by dissolving copper wire in sulfuric acid, with few impurities. Copper wie as the anode will go into solution and be plated onto the anode = positive from the power source. Neil
Q:Copper and the effects on the body?
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:Please, HELP!!! (Copper Iodide)?
4.5000 - 4.000 = 0.5000 grams of iodide 0.5000 grams of iodide @ 126.90 g/mole = 3.940e-3 moles of Iodide 4.000 - 3.8125 = 0.1875 grams of copper 0.1875 grams of copper @ 63.546 g/mol = 2.951e-3 moles of copper each copper that reacted took at least one iodide... 3.940e-3 moles of iodide - 2.951e-3 moles of iodide for each copper = 0.989e-3 moles of Iodides left in excess for some coppers to have 2 iodides.... means that you made 9.89e-4 moles of CuI2 so how much, CuI was made: 2.951e-3 moles of copper - 9.89e-4 moles of CuI2 = 1.962e-3 CuI moles : 9.89e-4 moles of CuI2 1.962e-3 CuI mole ratio of CuI / CuI2 1.962e-3 CuI / 9.89e-4 moles of CuI2 = 1.98 the actual ratio is ....1.98 mole CuI to 1 mole CuI2 the approximate ratio os 2 mole CuI to 1 mole CuI2
