Q: I asked this question as part of a two-parter, but no one responded to this part, so I'm posting it alone.I found a page online that said to use a paste of salt and lemon juice to polish copper and then wash it off right away with soap and water, so I polished a copper bracelet this way. However, large areas of the bracelet turned a white/rainbowish color, and I need to know WHY. Did I do something wrong? I thought oxidation was always black or green. Is that not true?Please do not just post your own copper polishing methods, unless it is accompanied by the reason why I now have a piece of metal which is now part both copper and whitish/rainbowish, since THAT is what I want to know. Thanks!: The nearest thing I could find to white residue on copper indicated that it was a residue of the cleaning agent. I would either rinse it again and dry completely, or try another method of cleaning. The ketchup sounds interesting and inexpensive. They sell copper cleaner at the grocery. Probably no better than lemon and salt... probably just cream of tartar and salt in fact. Good luck!

Q: I am 21 years old and i have the copper iud inserted about 16 months ago. For the past year or so my sex drive has decreased so much. I have 3 year old daughter and am married. I just want to know if anyone had had this or any side effect possibly caused by the iud. My husband and have concerted removing it.: Your copper IUD can't really do that, because it doesn't tamper with your hormones at all... The only way it could interfere with your sex drive would be if the device itself was causing apprehension for either you or your husband via pain or discomfort during intercourse. Otherwise, I don't think it's your IUD; there's nothing in it that would have that effect.

Q: What do you need for brass tube welding?: 1. tools: welding machine (hand welding gun or automatic welding gun), combustion supporting agent (oxygen), combustion agent (acetylene)2. materials: brazing, silver soldering (copper silver electrode without new flux)3. clip, fixture: fixed copper pipe position4. tooling: glasses, gloves, leather front hanging

Q: I was wondering if scrap yards take copper wiring that have had the rubber burned off of it. Because someone told me that when u go to cash in ur copper wiring it cant have the rubber burned off of it. My copper has a green type of rust on it: As a young boy I grew up stripping copper wire, my dad owned an Electrical business so scap copper was easy to find. I made a lot of money running a razor blade down the wire and pulling that gimp off, see then you've got # 1 copper, worth the most. I burnt copper over a burn barrel on occasion, but then it's worth a lot less. But for any wire smaller than number 8 you cant strip it so you may as well burn it. Because with the insulation on it it aint worth all most anything.

Q: Who can tell me the weight calculation formula of copper tube?: Copper tube (outer diameter thickness) * thickness *0.02796Brass tube (outer diameter thickness) * thickness *0.0267That's theoretical weight per metre

Q: My hubby has a copper figurine of a scorpian and was wondering if it was safe.: There are water conditioners meant to take care of copper. However, it would be much better and cheaper not to put the copper figurine in the tank in the first place. Put it on a shelf instead.

Q: A-level physics tomorrow. Please help me with this question(s): Copper is extracted from its ore, copper pyrite. The ore is roasted in a limited supply of oxygen. The following equations describe the process: 1. 2CuFeS2 (s) + 4O2 (g) ---&gt; CuS2 (s) + 3SO2 (g) + 2FeO (s) 2. Cu2S (s) + O2 (g) ---&gt; 2Cu (s) + SO2 (g) a. (i) Calculate the number of moles of CuFeS2 in 200g. (ii) In the experiment 88g of Cu2S is produced from 200g of copper pyrite as per equation 1. Calculate the mass of Cu produced from 200g of copper pyrite. (iii) Calculate the percentage of Cu in copper pyrite. Please help me with these questions. Question (i) I can do, but don't know how to do the rest. Thank you!: Copper is extracted from its ore, copper pyrite. The ore is roasted in a limited supply of oxygen. The following equations describe the process: Since the amount of oxygen is limited, we need to determine the amount of oxygen which was needed for the second reaction. 2. Cu2S (s) + O2 (g) ---> 2Cu (s) + SO2 (g) The coefficients in the balanced equation determine the ratio of moles of reactants and moles of products. 1 mole of Cu2S reacts with 1 mole of O2 to produce 2 moles of Cu and 1 mole of SO2. Let’s determine the number of moles of Cu2S. For Cu2S, mass of 1 mole = 63.5 + 2 * 32.1 = 127.7 g; Moles of CuS2 = 88/127.7 Ratio of moles of O2 to moles of Cu2S = 2 : 1 Number of moles of O2 = 2 * 88/127.7 = 176/127.7 Ratio of moles of Cu to Cu2S = 1 : 2 Number of moles of Cu = ? * 88/127.7 = 44/127.7 We need 44/127.7 moles of Cu from the first reaction! Ratio of moles of SO2 to Cu2S = 1 : 1 Number of moles of SO2 = 88/127.7 We need 88/127.7 moles of SO2 from the first reaction! Let’s determine the number of moles of O2 in the SO2 1 mole of SO2 contains 2 moles of O2 Number of moles of O2 = 2 * 88/127.7 = 176/127.7 Total number of moles O2 needed for the second reaction = 176/127.7 + 176/127.7 = 352/127.6 I am still working!

Q: How do I avoid getting small holes in copper pipes? How do I solve this problem? We do have a water softener?: try grounding your water lines to an earth ground,,,,people that have these problems have switched to plastic water lines,,,,i have had plastic h20 lines for many years

Q: and what other substances can also do the same job as anhydrous copper sulphate and what is the colour change?: Anhydrous copper sulphate can be used as a qualitative indicator for water. The grey/ white anhydride turns blue in the presence of water. Another product that has these characteristics is cobalt chloride. In the presence of moisture the salt has a red colour, and the anhydrate is blue.Because of its distinct color change and the ease of hydration/dehydration , cobalt chloride is used as an indicator for water. It is usually combined with silica gel, which is a strong desiccant. When the silica gel has absorbed the maximum water, the indicator turns from blue to red. Drying the silica gel in an oven drives off the water and the substance can be used again.

Q: GREE air conditioner comes with copper tube. How many meters?: Generally with a three meters or so, let others installed machine, then 100 yuan a meter copper tube
