FAQ

Baring in mind that 1 mole of Copper = 63.5 gHow much current is necessary to liberate/ produce 0.5 kg of Copper in one hour?Working also if possible, thanks.

The reduction of copper ions into copper metal is described by the chemical equation Cu2+ + 2e- -----> Cu Current in amperes (I) equals charge in coulombs (q) divided by time in seconds (t) t = 1 hour = 60 x 60 = 3600 seconds Now we need to determine how much charge is necessary in one hour. This can be done using stoichiometry. We know that for every 2 moles of electrons, we produce 1 mole of copper metal. (500 g Cu) x (1 mol Cu / 63.5 g Cu) x (2 mol e / 1 mol Cu) x (96500 C / 1 mol e) = 1519685 C Divide charge by time, and we get around 422 AMPS of current, which is a tremendous amount of electricity.

I recently discovered that the stove downstairs in my home wasn‘t working. I shut the gas off (it‘s propane) and removed the stove, now there is just an open copper pipe about the diameter of a dime. Once I turn the gas back on propane is going to come pouring through it, so I need a permanent way to clog the pipe up (I don‘t intend on using the stove anymore) which won‘t leak propane into the room. Thanks.

When you disconnected the stove there had to have been a fitting that you undid, correct? If so, go to the hardware and get a gas valve that will fit on that fitting and install it. Shut the valve and turn on the gas, problem solved.

But the problem is consuming of copper itself in it's natural form is harmful. I'd like to know how can copper be converted into edible substance, for example, edible copper leaf or dust. What I want to know is how is copper converted into dis-harming consumable element further which can be used in medicine.

I'm afraid this is impossible. This is because copper is an element and has a specific set of chemical properties which can't be changed. For example, the sulfate salt is blue and can't be made orange and remain the same compound. Copper in fact is an element, which means it can't be changed in any way and remain copper. Granted a soluble copper compound can be made insoluble and less toxic. For example copper sulfate can become copper sulfide when mixed with sodium sulfide. The copper sulfide will be very insoluible and much less toxic than the sulfate. However it might react with stomach acid and form copper chloride which is very soluble and hydrogen sulfide which not only smells bad but is just as toxic. It sounds to me that you are relying on some physical property of copper to supress cancer. I've seen a lot of copper bracelets, but copper has no known physical properties which would supress cancer in any way. Copper is not magnetic or radioactive. Radioactive materials in fact can be used to treat cancer. Perhaps a radio isotope of copper could be used for this purpose. I don't know how safe it would be however. I would definetly not want to wear anything radioactive around my wrist.

Is copper attracted to magnets.Cause i have a copper 1 cent coin and copper wire and they were not attracted.Also since steel wire is attracted, can it be used for electricity and as and electromagnet?

Copper is not attracted to a magnet. Steel, iron, cobalt, and nickel are the only magnetic metals. The metal used in an electromagnet does not have to be a magnet material. copper is the best for this application. PS, a US penny is mostly zinc with a little bit of copper plating. .

How much Copper (solid) can be made by reacting 0.47 moles of Sodium with 26g of Copper(II) Nitrate?2Na(s) + Cu(NO3)2 --> 2NaNO3 + Cu(s)

what you need to do: figure out how many moles of copper nitrate you have (g*mol/g = g*1/MW = mol) figure out which of sodium and copper nitrate is the limiting reactant (ie which will get used up completed, based on the number of moles) how many moles of copper will then be produced -- if you then want your answer in grams, multiply by the molar mass

Here is the picture. The copper tube comes into the gas source on the map. I'm in doubt at the switch. The black line is electronic ignition, and the pipe next to the black lineWhat is the working principle of the gas stove on the map above, copper into the gas source, to switch on the question at me, the black line is the black side of electronic ignition, tube has several holes, why not leak, electronic ignition below, how on fire?

First of all, the bending pipe you mentioned is an iron pipe, not a copper tubeThe two nozzle is copper, your question is 6 holes in each nozzle on the right, and this is the first gas nozzle holes 6 holes in the vertical direction of the jet out, because the gas is ejected with kinetic energy, it can be from 6 small hole injecting air into the Venturi tube, then two times air supply through the throttle.

1. Would the conductivity of copper be a physical or chemical property?2. What are some physical properties of copper?3. What are some chemical properties of copper?

copper is a mineral it forms naturally in the earth. it's in the earths crust as an elementle form. it is a mineral found in deposits called ores.an ore is a mineral rich rock. they form during sedimentary,igneous, or metamorpic rock cycle changes. they are literal veins in the earth when hot underground water magma is cooled some ores are formed settled and hardened into mineral. thats how you get the physical property. the chemical property of copper is mined and made into copper wire, like alluminum, coal and oil. they are all natural resources made into everyday materials from the enviroment

A copper pipe, used for plumbing from the water main to a house, is 5 meters long and has a circular cross-section 3.2 cm in diameter. There is a 2.4 cm diameter hole in the center of the cross-section for the entire length of the rod.

The cross-section area is pi*(1.6 cm)^2 - pi*(1.2 cm)^2 pi * (2.56 - 1.44) cm^2 3.51858 cm^2 The length of the pipe is 500 cm, so the volume of copper is 1759.3 cm^3 The number of cubic centimeters in a cubic foot is 28316.85, so the density of the copper is 0.01974 lb_m per cc Thus, the weight in pounds is 0.01974*1759.3 34.7 pounds
