Q: each unit of copper (II) sulfate? Please show me your work!: Copper (11) sulphate is CuSO4.xH2O MW is 62.5 + 32+ 64 + 18x = 95.14 + 18x If it is 25.5% Cu then 62.5/(95.14 + 18x) = 25.5/100 rearranging then 62.5/0.255 = 95.14 +18x = 245 18 x = 245-95.14 = 149.96 x = 149.95/18 =8.3

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!: I rather have an identical difficulty,I used to apply point 40 bleach. yet i recently switched because of the fact is somewhat time ingesting and undesirable on your hair. I switched to Revlon colour silk alluring colour-05-extremely mild ash blond. yet I go away it on for 60 minutes somewhat of 25. yet i could recommend you utilize pink shampoo(that's made to get the brassy/copper tones out of hair) yet im unsure what that's reported as. that's slightly costly in spite of the undeniable fact that. Or bleach it with point 40 bleach. It labored for me.

Q: I am working on getting a contract through a copper plant and what I am supposed to be doing is cutting 40x20 inch copper discs, 40 inch circles 20 inches deep, I started today using a concrete saw, it took 2hours to simply make one cut and that destroyed an entire blade, what would be a more efficient option of doing this: Copper is tough. Perhaps you can cast those gigantic copper slugs instead ot cutting them, then lathe and grind them to specs. That will take substantial time, but you won't be watchinng a saw burn up.

Q: hi i have just purchased some old copper pans and a coffee pot with a sugar bowl .Does anyone know how to clean the outside because they look tarnished .please help thanks: All you do is halve a lemon and sprinkle table salt on the cut side. Rub the lemon over the copper surface and bingo, a beautiful shiny surface emerges in no time! I couldn't believe my eyes. A lovely lemon smell, no mess and no nasty residue to rub off my hands or the kitchen sink. Best of all, when you're done, the lemon goes down the garbage disposal and freshens that up, too. This is how my Mom cleaned her copper but I do not think her copper had the lacquer finish on them..try on a little spot first. Hope this helps..

Q: My family is going to install an air conditioner cabinet 3P living room, living room about 35 square, but copper should at least ten meters, not more than ten meters of this brass, have little impact on the effect of air conditioning, if installed air conditioning effect is just a little bit, with no what meaning, or my apartment layout ventilation effect quite good, and the living room cabinet household should also rarely, we can talk about the brass ten meters, have much impact on the air conditioner? Like my family this phenomenon, we can give an opinion ah!: The living room 35 square is very big, installs 3 air conditioning to be possible. Connection pipeline ten meters, there is no big impact, more add a little Freon can, cloth pipe to flat, bend 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. The extension wires should be of the same thickness, and the interface is covered with waterproof adhesive tape. Take care of the drain, and don't cut it

Q: I am looking at getting one of these (I have risk factors for the hormonal Mirena IUD). Does anyone have any personal experience with the copper one? It seems like everyone I know has the Mirena instead.: I have the copper IUD and haven't had any problems with it. When I had it inserted it felt about the same as a pap smear. Had some mild cramping the rest of the day and the following day but Advil helped a lot. The copper IUD can cause you to have heavier periods and more cramping during your period, but since I have heavy periods to begin with I haven't really noticed any change. I also haven't had and more or less cramps than I used to, but everyone is different so everyone's body reacts differently. But I will say that, for me, it's been one of the best decisions I've made. Definitely worth talking to your doctor about.

Q: Which is more suitable for household water pipes, plastic copper tube and copper lined PPR pipe?: Did not come into contact with plastic coated copper pipe, the two pipes at home are considered very good, is very suitable. The outer layer of the plastic for anti-corrosion, key copper thickness and quality inside, choose the brand, installed well generally with no problem for decades, the quality of copper are better than other materials.

Q: rare coins,copper piping, whatever else?: Exposure to chlorine, even if in the form of chlorides (like salt) causes coper to develop to develop a green tarnish. The Statue of Liberty has such a patina, for instance.

Q: I did an experiment with copper and iodine in AP chem, and now I have questions to answer. It is asking how the observed will be larger or smaller than the true ratio if some of the copper iodide compound was knocked off the copper wire before the wire was weighed after the copper was exposed to gaseous iodine. I assume it is talking about copper to iodine ratio, but I don't really know. I know this would make the measured amount of compound formed larger, but I don't know how it would effect the ratio. If anyone can figure out what I'm rambling on about, help would be greatly appreciated.: I think more details on your experiment are needed, but I'll give it a shot assuming this is how your experiment was intended to proceed (if successful): 1. Weigh a clean copper wire. Purpose: estalish starting mass of copper 2. Expose copper wire to gaseous iodine Purpose: react copper with iodine to form copper iodide 3. Weigh the copper wire again Purpose: to find out how much iodine reacted with the copper (by subtracting from this mass the original mass of the copper wire) 4. Scrape off compound from wire and weigh it: Purpose: to find out how much copper is in the compound (by subtracting calculated amount of reacted iodine (step 3) from the weight of the compound. 5. Determine the ratio of copper to iodine to find empirical formula for copper iodide. I hope that is correct. If so the ratio of copper mass to iodine mass is given by: (mass Cu)/(mass I) = [(Mass of Compound Scraped off)- (Mass Reacted Wire - Mass Unreacted Wire)] / (Mass Reacted Wire - Mass Unreacted Wire)) Let's use some hypothetical data: mass original wire =10g mass reacted wire = 11 g mass of compound scraped off = 2 g ratio of Cu/I = [2g - (11g - 10g)]/(11g - 10g) = 1 g Cu/1g I If 0.1g compound had fallen off we would have the data: mass original wire = 10g mass reacted wire = 11g - .1g = 10.9g mass of compound scraped off = (2g - .1g) = 1.9g ratio of Cu/I = [1.9g - (10.9g-10g)]/(10.9g-10g) = 1.11 So it would appear that if some compound had fallen off, your experimental results would predict a higher copper/iodine ratio than the true ratio. I hope this helps - that's my shot anyway (w/my assumptions about your experiment)
