Q:Which statement best answers the question, &quot;Why is copper a good conductor of electricity?&quot;?AnswerA.Copper atoms have a loosely held electron in their outer shell that is able to move freely to other atoms.b.Copper atoms are tightly bound and are able to work with other copper atoms to exchange electrical charges.C.Copper has an equal number of protons and electrons making the flow of current possible.D.Copper's outer shell electrons are not balanced and must join with other copper atoms in order to be stable.I know it's either A or B I just don't know which one. Please help?: Copper is a ductile, semi-precious metal with very high thermal and electrical conductivity. Pure copper is soft and malleable; an exposed surface has a reddish-orange tarnish. It is used as a conductor of heat and electricity, a building material, and a constituent of various metal alloys. The major applications of copper are in electrical wires (60%), roofing and plumbing (20%) and industrial machinery (15%). Copper is mostly used as a metal, but when a higher hardness is required it is combined with other elements to make an alloy (5% of total use) such as brass and bronze. A small part of copper supply is used in production of compounds for nutritional supplements and fungicides in agriculture. Machining of copper is possible, although it is usually necessary to use an alloy for intricate parts to get good machinability characteristics. The atomic number of copper is 29, which means it has 29 protons in the middle and 29 electrons moving around the outside. (The 29 negative charges of the electrons and the 29 positive charges of the protons balance out, so the atom is neutral when all of its electrons are in place.) Copper has two electrons in the innermost shell, eight in the next shell, eighteen in the third shell, and one in the fourth shell. This means that the first three shells each have as many electrons as they can hold, and the fourth shell has one lonely electron. (The fourth shell can hold up to 32 electrons.) Because this one lonely electron is all by itself in the outer shell, it can easily separate from the rest of the atom and go roaming around, which makes copper a very good conductor.

Q:The black water does not come out all the time. When you first turn on the water it is black. Is there any way to stop it?: Sounds like your pipes are starting to corrode, the only way to stop the black water is to replace the pipe causing it. When the water is off the black corrosion builds up and when you turn the water on it all comes out at once, when the water is running there is still black coming out but is a small amount that you cannot see or do not notice.

Q:Calculate the radius of a copper atom. r =__________ pm: Hi simone! I am answering you from Italy. The question is really difficult to solve. My suggestion is as follows: Atomic weight of Copper = 63.55 g/mol Copper density = 8.97 g/cm^3 You can easily see that 8.97 grams of copper has a volume of 1 cm^3. You have to calculate the number of Cu mole which occupies 1 cm^3. That means: 8.97 g copper /63.55 g/mol = 0.1411487 mol in 1 cm^3 which means that 0.1411487 mol *6.022* 10^23 molecules/mol = 8.49997*10^+22 molecules of Copper in 1 cm^3. From these data you can calculate the volume per molecule =1 cm^3/8.49997*10^+22 molecules= =1.17647*10^-23 cm3/molecule You have to consider the molecule shape as a sphere. The volume of a sphere is given by: V= 4/3 pi*r^3 --> where pi = 3.14 so, 1.17647*10^-23 = 4/3 pi * r^3 --> r = 1.41091*10^-8 m = 141.091*10^-10 --> m = 141.091 Angstroms. Angstrom to picometer (A to pm) --> pm = 100 *A 141.091*100 Amstrongs = 1410.91 pm --> 'pm' is the abbreviation of picometer. Result: r = 1410.91 pm NOTE: 6.022* 10^23 molecules/mol is the value of the Avogadro constant [NA] which is defined as the ratio of the number of constituent particles [N] (atoms or molecules) in a sample to the amount of substance n (mole) through the relationship NA = N/n [Source: Wikipedia] Kind regards from Italy.

Q:here's my knowledge of copper motors. it consists of 2 components, stator and rotor. both parts made of stacks of laminations with slots. the rotor slots are filled with copper rods and the stator slots are wired in a certain way.here's my question, if i want to design a motor having a certain spec for power output, rpm, size, etc... how do i design the slots in the rotor ? i have connections for winding stators, but nobody i knew that can answer me the secrets of rotor design. can somebody give me some clues on rotor design? and how are they manufactured? i heard that people just use hammer to push copper rods in the rotor, is that true?thanks for reading my question!: Actually Ba, aluminum requires a TON of energy to extract. You'll only see aluminum being purified near sources of cheap energy. As for why aluminum being cheaper, it's just more plentiful. It all comes down to scarcity, Plus, there is a lot of demand for copper, which will also drive up the price.

Q:just wondering where would they be located?: Most new homes use PEX type piping for both water supply and heating. Previous homes used copper. And earlier homes used pipes that were galvanized.

Q:My grandfather passed away recently and left me roughly $520 worth of wheat and indian head pennies. I'm no coin expert but I know enough that they are made from copper which pennies now a days are not, and that wheat and indian pennies must have some sort of value. How could these rolls be worth? And what should I do with them? Sit on them, sell them, what?: A copper penny made before 1982 is worth about 2.4 cents in copper value alone. It is illegal to deface the penny by melting it down, but that may be changing in the near future. There may also be a number of collectible coins. I would start to sort them looking for any collectibles and store the rest. copper is going to be a valuable commodity one day soon.

Q:I‘m an investor, and I buy foreclosed houses, renovate them, then re-sell them as nice homes. Twice, I‘ve purchased a house where someone had gone inside, then removed and stole all the copper plumbing in the basement. Then I had to spend money to re-pipe it in order to get the water back on. Both times, the house was a HUD house, rather than a bank-owned one. I know that HUD has master keys for all of their listed properties for sale (each house could be one of 5 keys), so do thieves have a way of getting copies of HUD keys? They are basic ordinary house keys that can be easily duplicated at any hardware store.You‘d think HUD would have better security than that, like using special keys that can‘t be duplicated.: if the price of scrap copper is high any where its easy to get copper it will be stolen the chances of getting caught pinching copper pipes and wires from empty houses is? Does it bother you that your making money on houses taken from people on the bones of their ****?

Q:i would like to know the procedure of producing copper sulphate and its solution of Cu + H2SO4: A source of copper carbonate is obtained, such as by the treatment of a spent alkaline etchant solution with an acid, such as H2 SO4. The resulting copper carbonate slurry is dried and put into a reactor. The exact amount of water to form CuSO4 . 5H2 O is added to the reactor and then sulfuric acid is slowly added with agitation until the correct amount of H2 SO4 is added to make CuSO4 . 5H2 O. The mixture is agitated while cooling and the resulting crystals are small and the yield is almost theoretical with no mother liquor remaining.

Q:Add a 1/2 cup of copper to a Rubber tree plant soil what Will the out come be?: Copper compounds are usually used to increase soil acidity. If your rubber tree is a Ficus elastica, it will be happier in a neutral to slightly caustic pH. If you've already added it, no need to do anything however, as it is practically impossible to permanently change the pH of a soil, and it will return to the original in time as normal watering will flush out the copper. If you haven't added it yet, don't.

Q:when copper was discovered and when it was found: Copper, as native copper is one of the few metals to naturally occur as an uncompounded mineral. Copper was known to some of the oldest civilizations on record, and has a history of use that is at least 10,000 years old. A copper pendant was found in what is now northern Iraq that dates to 8700 BC. By 5000 BC, there are signs of copper smelting, the refining of copper from simple copper compounds such as malachite or azurite. Among archaeological sites in Anatolia, ?atal H?yük (~6000 BC) features native copper artifacts and smelted lead beads, but no smelted copper. But Can Hasan (~5000 BC) had access to smelted copper; this site has yielded the oldest known cast copper artifact, a copper mace head. Copper smelting appears to have been developed independently in several parts of the world. In addition to its development in Anatolia by 5000 BC, it was developed in China before 2800 BC, in Central America around 600 AD, and in West Africa around 900 AD. There are copper and bronze artifacts from Sumerian cities that date to 3000 BC, and Egyptian artifacts in copper and copper alloyed with tin nearly as old. In one pyramid, a copper plumbing system was found that is 5000 years old.
