Q:one cent 1943D copper?
Check with your local coin dealer or check one of the coin books at the library.
Q:drinking water in a copper vessel?
copper vessels are very nice, they shine a lot and can be cleaned with lemon ! For further details, contact my mom.............
Q:chemistry copper cycle lab question help!?
I'll leave it to you to work out all the details for your procedure, so here's the gist. There is no acid which will react only with the copper cladding on a penny. Therefore, you can mass some pennies, and then dissolve them in nitric acid to make a mixture of Cu2+ ions and Zn2+ ions. Then essentially repeat your copper lab by adding NaOH and then warming it to make CuO, and decanting the solution containing all the other ions. You'll drag the zinc ions along as Zn(OH)2 initially, but it won't matter. Dissolve the CuO and any zinc compound in H2SO4. At the last step you will add zinc metal to replace the copper. Recover the copper metal, wash it and allow it to dry. Then mass it. Determine the ratio of the mass of the copper metal to the mass of the pennies, and express the fraction as a percentage. Subtract the percentage of copper from 100 to get the percentage of zinc.
Q:How Many Grams of Copper Sulfide...?
Copper metal + Sulphur ---> Copper (ii) sulphide which can be expressed by the balanced equation, Cu + S ---> CuS thus, 1 mole of copper metal reacts with one mole of sulphur to produce one mole of copper (II) sulphide The atomic weight of copper is 63.5, the atomic weight of sulphur is 32 1.35 grams of copper / 63.5 = 0.021 moles of copper metal 0.021 moles of copper metal will react with 0.021 moles of sulphur to produce 0.021 moles of copper (II) sulphide 0.021 x atomic weight of sulphur (which is 32) = 0.672 = 0.021 moles of sulphur 0.672 + 1.35 = 2.022 grams of copper (II) sulphide produced
Q:Any doctors in the house?....Fatty Liver and Copper?
Copper in the IUD will not lead to Wison's disease. Wilson's disease is a genetic disorder/disease of copper metabolism.
Q:Is there a copper alloy wire that does not tarnish?
Chances are your untarnished copper wire is clear-coated. You can do this yourself with a spray or brush-on varnish, best after the jewelery is made so it doesn't crack when bent. This is what many jewelers who work in copper use.
Q:Brass is an alloy of copper and zinc.bronze is an alloy containing 80% copper,4%zinc and 16% of tin.?

Q:Which Copper Penny is Worth $10,000 to 1 Million Dollars?
Million Dollar Penny 1944
Q:Why is Hydrogen more active than copper?
Definitely Hydrogen. The radii of copper is longer than Hydrogen and that leads to a higher shielding effect. Shielding effect means inner electrons are block and therefore copper atoms can easily lose electrons to become octet. Besides, Hydrogen atoms have a high ionization energy (1312.0 KJ/mole). Ionization energy refers a force needed to lose an electrons. The higher ionization energy, the harder to lose electrons. I hope it helps and I am glad! Because I am not an expert in this field!!=]
Q:Is a two crowns King Henry VIII copper coin have any value?
It's not a coin. It's a private-issue copper 'round' sold either as a collectible or to the naive person that thinks they're making a smart investment in copper. All 'AOCS Approved' means is that the American Open Currency Standard, a private company that promotes the idea of people making their own currency and bartering with it amongst like-minded individuals, has agreed to the use of their name. In my mind, it's not worth much, because one Troy ounce of copper - what this probably is - contains roughly 25 cents in pure copper. I wouldn't trade you a US quarter for it, because I can use that quarter towards buying something anywhere. It would take me a long time to find someone who would give me more than 75% of the bullion value, assuming they even were interested in a single round. Most places that buy copper buy it by the many, many pounds. It probably has more value as something to collect. Maybe up to $5 to the right collector.
