Q:i have a 50 inch projection tv how much copper is in it: Yes there is copper in projection tv's. In fact there is copper in all tv's. Copper can be found in wiring as well as the printed circuit boards. As for how much copper is in a 50 inch projection tv - not enough to make you any appreciable money (my quick guesstimate would be a couple of pounds of copper at most).

Q:how many years was copper mined: a lot.

Q:looking for copper to make a motor around my house...where do i find copper? is there any in my old CD player/ radio? if so where? is there any in a flashlight? where?: Most old radios have wires of copper. Modern ones have circuit boards with components on them, few if any wires. Headphone cables. Video cables. Extension cords have copper. None in a flashlight, as a bar conducts back from the bulb holder through the switch and to the spring that touches the battery. A transformer has the perfect type of wire for motor coils. To make a motor, you want thin solid wire with a lacquer coating for insulation. That will give you lots of close windings. Most hardware stores have lots of plain copper wire. But you will have to insulate it yourself.

Q:I need to find the price of anhydrous copper sulfate and compare it to the price of pentahydrate of copper sulfate.i just can't get the price of anhydrous copper sulfate in usa: It is simple to make. Just heat the bluestone and it turns white and is CuSO4.

Q:Why cant copper react with calcium Hydroxide?: calcium is more reactive than copper. which means that the calcium will react faster than copper and it will stay that way in the presence of the less reactive copper

Q:How would you polish and seal a 4 foot copper pipe?: If its to wet the eggs will get mold and rot. If its to dry they will dryout and die.

Q:When building a bathroom, what kind of pipe should be used? PVC or copper? And why?: Copper tubing is far superior to PVC. PVC has a life expectancy of 10/12 years before it starts to deteriate. Copper lasts a life time. It makes a neater job of pipework than PVC, and is pliable enough to be easily bent. into any shape and sti;ll look good.

Q:How easy is it to get poisoned from copper? In powdered form it is easily lethal if ingested, with similar consequences to that of arsenic. but what about water running through pipes? Does it spall off into the water as it passes though? It would seem that copper pipes that have oxidized inside must more readily spall the oxide into the water.The reason I ask- I‘d like to buy a vintage coffee grinder- but the hopper is copper, which is oxidized to almost green. My oily coffee beans would be in contact with this surface all the time. Does this pose a health hazard? Is it any less hazardous than non-oxidized copper?I drink a lot of coffee- and I am usually fairly committed to the household appliances I invest in- I don‘t want to wind up a mad hatter in a few years!: EVERYTHING is poison, it's a question of quantity. Also there is some, however small, amount of everything in everything. Arsenic is present in water but at very low levels it is not a problem. Many poison metals are nutrients in small quantities. Take zinc, which is illegal for industries to discharge into the sewer but is used to prevent colds. Copper oxide does not spall and copper pipes are used just because they don’t corrode. Copper will normally dull (patina) and if it were bright that would indicate that some was being rubbed off in use. If the corrosion is green it’s not the oxide. I’d scrub it out and hen figure that anything left is going to stay there. Copper is often used in food contact applications such a candy making. Strohs beer (not made anymore) was advertised o be made in copper kettles and I understand it was about 6ppm copper. Most city sewer plants won’t let you discharge more than 1-2 ppm in the sewer! I drank a lot of Strohs and I’m not dead yet. I’m thinking alcohol and coffee aren’t good for us, so forget about a little copper. As for the Mad Hatter that was mercury from it being used as a preservative in the beaver fur used to make the hats. SOME mercury is in the water and air but again, how much makes ALL the difference.

Q:Zinc metal reacts with copper(II) ion in solution to produce zinc ion and copper metal, as follows.Zn(s) + Cu2+(aq) ? Zn2+(aq) + Cu(s)You add 7.675 grams of Zn metal to 27.0 mL of 0.270 M CuSO4·5H2O and allow the reaction to proceed until the blue color of the solution is gone. You note that copper metal is plating out on the zinc pellets. How many moles of Zn have you added to the flask? (Unit is mol).How many moles of Cu2+ ion are in the solution? (Unit is mol).How many moles of Zn will have reacted with the Cu2+ when the reaction is complete? (Unit is mol).How many moles of Zn will remain unreacted? (Unit is mol).What mass of Zn will remain unreacted? (Unit is g).How many moles of Cu metal will be produced? (Unit is mol).What mass of Cu metal will be produced? (Unit is g).When the metal pellets are removed, dried, and weighed, what should be their total mass?: Molar mass of zinc is 65.40 g/mol, of copper 63.546 (you can find that in a periodic table of elements). Amount of zinc equals n=m/M; 7.675 g/65.40 g/mol = 0.117 mol. Molar concentration (c=n/V) of CuSO4?5H2O is 0.270 mol/L, volume equals 27.0 mL = 0.027 L. Amount of CuSO4?5H2O equals 0.27 mol/L X 0.027 L = 0.000729 mol. Each mol of CuSO4?5H2O gives one mol of Cu2+ ions (CuSO4→Cu2+ + SO42-), so amount of Cu2+ ions in a solution is 0.000729 mol. One mol of Zn reacts with one mol of Cu2+ (Zn + Cu2+→Zn2+ + Cu), therefore 0.000729 mol of Zn reacted. 0.117mol (starting amount)-0.000729 mol (reacted amount) = 0.116 mol of Zn remained in a solution. That means 7.586 g of zinc remained (0.116 mol X 65.38 g/mol). One mol of Zn reacts with one mol of Cu2+, therefore 0.000729 mol of Cu is produced, which is 0.046 g. Total mass of pellets (copper coated zinc) is (starting mass of zinc – mass of reacted zinc) + mass of produced copper: 7.586g Zn + 0.046 g Cu = 7.63 g.
