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:Air conditioning copper pipe in Chengdu where to sell?: Where the air-conditioning can be sold, the key depends on what you use to do? If you buy a small amount for his use, contact the air conditioner.

Q:Can you tell me anything about copper and the environment. Like pollution and how it affects the air, water and soil. Just anything. Thanks!: Copper is poisonous so, if you have copper compounds that are water soluble, too much will kill fish and plants. Some uber-aquarium afictionadoes intentionally add just enough copper compound to their aquariums to keep the algea from growing but not too much to kill their fish.

Q:Why does the air conditioner use a copper tube to deliver coolant?: Why air conditioners use copper tubes to transport refrigerants for the following reasonsCorrosion resistance: air conditioning in the work process, the tube surface temperature is very low, will the water vapor in the air into water, adsorption on the surface, if it is iron pipe, life certainly won't be very often.For installation: the installation of air-conditioning in accordance with the different structure of the house, you need to bend the tube shape, which is the most appropriate copper tube. There are joint bell mouth, tube, welding, iron is easier than.

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.

Q:11.In many communities, large, buried iron pipes carry the water supply to the houses. Whenever it is necessary to connect the house plumbing (often copper) to this pipe, regulations usually require that an official inspector observe the connection. Explain why?: Copper and iron react to one another in the presence of dirt and minerals to create a flow of electrons and a resulting corrosion of the metals. In order to prevent the reaction from occurring, a special fitting is used to join the copper and the iron together. The fitting is referred to as a dielectric fitting. It will not allow electrons to flow and thereby prevents the corrosive action from taking place. If the dielectric fitting is not installed or if it is installed incorrectly, the electron flow and corrosion will result in the pipe bursting within a relatively short time span of a few years. With the dielectric fitting properly installed, the pipes should have 25 to 35 years minimum life spans.

Q:can i use copper pipe for natural gas?: Check your local gas codes or you can go check the NFGC codes at one of the links listed below. I doubt that you will be able to use copper anymore. Last time we ran an underground gas feed it was feeding a garage and we were required to run that new orange plastic piping for it. You can check the links below and go to the National Gas Code site. You should always check your local codes too.

Q:How do I repair a pin hole in my copper pipe leading to my hot water heater?: There are patch kits that have a neoprene sleeve and a ratchet type clamp. Will last a long, long time Or turn off the water, get a piece of copper pipe and then cut out the damaged piece and insert the new piece using compression fittings available at CTC. Saves messing with solder

Q:Is there anything I can do to prevent the water from dripping constantly? Why is the water blue when it hits the floor?: Because the air in your basement is humid and the water in your pipe is cold. This causes a thing they call condensation. The best fix for this would be to buy some pipe insulation at the hardware store and install on your dripping pipes, or put a dehumidifier in your basement to take out some of the moisture.

Q:Air conditioning copper 5 horses can be used in any three, general air conditioning 5 horses and 3 Brass air-conditioning should be how many mm diameter copper tube: Can not be used in principle, because the power is different, refrigerant flow is not the same, air conditioning in the design of the diameter ratio should be the best match, and after the replacement of diameter, air-conditioning conditions will change. Doubling the diameter by doubling the area.It can be used only if it is used on an evaporator.So it's better not to substitute reluctantly.
