- Q: The copper coin was in a evaporating dish containing zinc metal, tunred gray and then was heated in a busen burner.
- Copper and zinc combine to make brass. For a while the fresh surface of the brass will look gold, over time it will oxide to reddish brown. The layer of zinc atoms on the surface of that penny are actually moving down into the copper when you flame it. A thin layer at the surface is becoming brass.
- Q: I need it to be as pure as possible and locally if available, (i live in long beach). I have no idea where to get a pure block of copper from. any help would be much appreciated.thanks,
- As kaushal noted, copper wire is usually very pure copper. You can hammer a thick piece of wire until it is about 21 by 21 millimeters, of uniform thickness. Then electroplate, until it is 5 mm in the thinnest part, then trim, grind and polish until the dimensions are close enough for your purpose. The electroplating will further purify the copper if you keep the plating current at one amp or less. A 3 to 5 volt power cube rated one amp or a bit more can be your source of dc current. Dissolve as much pure copper sulphate in distilled or deionized water, as will dissolve, then add a bit of sulfuric acid. You can make your own copper sulphate, by dissolving copper wire in sulfuric acid, with few impurities. Copper wie as the anode will go into solution and be plated onto the anode = positive from the power source. Neil
- Q: My ceiling is coming down because of a pin hole leak in the plumbing system. Whats the best way to seal it?
- Most likely you're talking about a leak in a supply line between the shutoff valve and a sink or other fixture. If so, people don't repair these, they replace them. These are usually chromed and a little bigger than a pencil compared to a supply pipe before the shut off which will be as big as your finger. You can probably replace this yourself. If this is what's leaking, it will cost $3 to replace and any friend can help you with a couple of wrenches. These come in plastic also now and some are real flexible. I had a misty leak and traced the cause to storing bowl cleaner with the cap off, under the sink and the acidic fumes from the cleaner corroded the pipe. It was ready to leak in a lot of places.
- Q: I'm doing a science project and I don't get this question:What are the properties of copper wire compared to the properties of the graphite from a mechanical pencil?Please awnser it!
- Copper is very good conductor of electricity as compared to graphite. 2 copper is used in fuses, while as graphite is not.
- Q: The closest copper pipeis at least 15ft from panel.its the main coming in to the house. how do i run a ground to it?
- It dose not matter how far away your closest copper pipe is. To properly ground your electrical service you will need to determine the size of the wires that are feeding your panel. Then you can determine what size of grounding wire to use. You can't just use a #6 ground as the other guy said. it will vary depending on the size of your service wires. Typical, to ground a service you will need to bond the grounding electrode wire to the----- The gas pipe that feeds your house, on the piping just past the meter The water pipe that feeds your house, before the shut off valve. The hot and cold water pipes at your hot water heater (unless they are pvc). A ground rod, 8 feet long - driven into the ground by your service. And then attach he wire to the grounding bus bar in your main panel. This grounding electrode wire must be a continuous piece of wire with no breaks, splices, or joints - unless it is spliced in a way that is approved by the nec (ie. exothermic welding). When you do bond the wire to the above items, you must use approved clamps. For more information please read the National Electrical Code, section 250 deals with grounding. This is by no means a complete list of the things you need to be concerned with, just a basic overview. Good Luck
- Q: The density of copper is 8.97 grams per centimeter cubed. What is the radius, in angstroms, of the copper atom ?Atomic weight of Copper = 63.55 g/mol
- From copper (8.97g/mL) and its molar mass you can calculate number of Cu atoms in 1mL: N=8.97/63.55*Na, where Na - Avogadro's number. Thus, N=0.85x10^23 atoms/mL. Since copper has cubic face-centered unit cell, it means that there are 4 atoms of Cu per unit cell. If you know the number of atoms in 1mL of Cu, you can calculate the volume of unit cell: V(unit cell)=4/0.85x10^23=4.7058x10^-23mL. Since 1mL=10^24 angstroms, then V(unit cell)=4.7059x10^-23*10^24=47.058 A^3. From unit cell volume you can calculate the cell parameter (the length of the side of unit cell): a=(47.058)^(1/3)=3.6103A. In face-centered unit cells it is assumed that atoms in cell corners and on the cell faces are touching, implying that the length of the face diagonal D will be equal 4*r, where r is atomic radius. Since you know cell parameter, you can calculate D and then r: 2a^2=D^2 => D= a*2^0.5 = 4*r Thus, r=a*(2^0.5)/4 = 1.276A, the radius of Cu atom.
- Q: how to c;ean the blue /green gunk from my bath tub due coming from the copper pipe. It like glue .
- No need to do these unless there's a change, or a obvious problem with your tires.
- Q: Whats stronger, pewter or copper, and what would be best used for a coin pewter or copper
- Pure copper is very soft. Also hard to melt due to rapid oxidation. Pewter is okay but gets dull Both copper and pewter are costly right now because of the high cost of copper and of the tin in the pewter.
- Q: How much would you get from a single say modern tv cord for its copper?
- Copper is Rs. 400 per kilogram. Used copper is around Rs 300 to 350 per kilogram
- Q: zinc-copper voltaic cell
- yeah, just the opposite of zinc- copper is the cathode, so it reduces Cu2+ + 2e- = Cu
