Q: I'm doing an experiment for the science fair, and my group is having a bit of trouble using a flattened copper pipe as a base. Does it work at all, or am I just horrible at making electromagnets?: base? I'm not sure what you mean by that, but I think iron (or, maybe easier to find, steel) would be far better than copper for the base. Copper is good for the windings of an electromagnets, but for the core, iron is better.

Q: can copper pipes be picked up with a metal detector: A GOOD metal detector maybe.but there is no need for you to go out and buy one. Water lines up to the point of entry into your house are the responsibility of your water department. Simply give them a call and they will come out and mark them for you.

Q: if copper sulphate will be used as a electrolyte and zinc and copper as electrodes....expalin the whole mechanism.......please......and tell me thet will zinc be at the higher potential or at the lower potential....i.e will zinc be negatively charged or positively charged and whyyy???: this is the a voltaic cell, two dissimilar metals ( copper and zinc) are immersed in an electrolyte ( a dissolved sulfate). If the metals are connected by an external circuit, one metal is reduced (gains electrons) while the other metal is oxidized ( loses electrons). copper is reduced and zinc is oxidized. The difference in the oxidation potentials of the two metals provides the electric power of the cell. Zn/ZnSO4 // CuSO4/Cu 2e- + Cu2+ ------> Cu reduction reaction of Cu ions to form copper metal. The valence state of copper is reduced from 2+ to 0 Zn --------> Zn2+ + 2e- oxidation reaction of zinc metal to a zinc ion Standard Reduction Potentials: Cu2+/Cu Eo = +0.340 V Zn2+/Zn Eo = -0.76V Cu has the highest reduction potential In order for a battery to work dE > 0 dE= Er - Eo dE = ECu - EZn = 0.34V - (-0.76V) = 1.12V this is the EMF ( electromotive force) Thats the way the battery works... sorry for my english

Q: It's an antique silver plated copper tea service from 1955.Thanks!: Plated Silver Value

Q: there is copper proteinate in my fish flakes that i feed my crayfish is this ok: Copper protienate can kill most inverts salt or fresh water.I say can because I've seen some cases where it didn't affect them at all. So you can take a chance...........

Q: I have a ton of pennies laying around and have started sorting and organizing them.Is it true that pre-1982 pennies were real copper, while post-1982 pennies are not? So if there were a ton of pre-1982 pennies, could they be cashed in for the value of the copper as well as the monetary?: It's true that pre-1982 cents are 95% copper (with a current metal value of 2.44 cents each) and that post-1982 cents have only a thin layer of copper plating over zinc (with a current metal value of a little over 1/2 cent each). But, what about the 1982 cents that you've skipped over? You will find both kinds dated 1982. The Mint made the switch during the production year. There are two ways to tell the difference. The best way is with an accurate metric scale. Copper cents will weigh just over 3 grams, the zinc around 2.5 grams. I don't have such a scale, but I've gotten the 'drop' test nailed down. Drop the coin on a hard tabletop and if it makes a 'ring' it's copper, if it's a dull sound, it's zinc. To double-check, drop a pre-'82 and post-'82 and compare. People cash in their pennies for more than face value all the time. There atre copper bullion buyers just as there are buyers of precious metals. They're harder to find, but they're out there. You can get from 1.5 to 2 cents each for large quantities. There are roughly 145 cents to a pound. Buyers go by the poundage, not the number of coins. They might go as high as $2.90 a pound right now with copper at $3.70, but I would expect something in the $2.25 - $2.50 range per pound.

Q: I just had the Paraguard IUD copper inserted about 2 days ago and I was spotting afterwards but now it looks like if I have my period blood like it got heavier I have to wear a pantyliner and I seen small clots but not like a ball only like thin pieces (maybe you know what I mean lol) but I was just wondering how long does this bleeding last. I just finished my period and now its like I started again! If anyone has the paraguard or people that have experience with this can answer thanks!: Did your doc warn you about the extra bleeding with paraguard? you might just bleed for days, but some bleed for months. extremely heavy periods on this.

Q: I attempted to make copper sulfate today by creating a near saturated solution of magnesium sulfate (in water) and electrolyzed the solution with copper diodes.However, the resulting mixture was a heterogeneous mix of a clear looking liquid and a yellow-brown precipitate at the bottom. I filtered the mixture once, and the precipitate that filtered out was a dark yellowish brown color.After doing this, the filtered solution was still a light yellow color. I know that a copper sulfate solution is supposed to be light blue, so I know that something is wrong here.What do I have in my filtered solution? Is it some kind of compound with sulfur, creating the yellow color? Also, the cathode was black instead of the natural copper color, and it would not wash off.Bonus: How do I remove the black coating on the copper?Thanks!: copper diodes?? ! do you mean copper electrodes? Is that what was wrong? Magnesium ions will not be removed in this electrolysis as H+ ions are discharged instead but the Cu anode should give Cu2+ ions Light yellowy colour suggest iron somewhere?

Q: 11. Cast-iron skillets take longer to heat up than copper ones, but they hold their heat longer. Why? Copper and iron have the same specific heat. Copper has a higher specific heat than iron. Iron has a higher specific heat than copper.21. What particles exist within plasma that do not exist in all elements in other states? free electrons molecules atoms free neutrons: More metal.
