- Q:What type of copper pipe weighs a total of 20lbs. ?
- You need to check the neutral wire at the breaker box for this circuit, then check the neutral wire at the three wire plug to make sure they are tight. (WHITE WIRE). Next open the dryer up at the back where the dryer is wired at and make sure that the dryer wire that is white and green are tight and connected together to the frame of the dryer as well. Every one assumes that everyone has a 4 wire dryer circuit not true. This changed in 1999 as far as the code goes and many counties do not adopt to the new code right away. If you have a dryer that has a three wire cord then it can be changed to a four wire cord if you have a four wire plug. It has to be done by a competent person who has the knowledge to ground the dryer frame and separate the neutral wire from that. If you have a dryer that is newer then the home you moved in to and it has a four wire cord it to can be changed to a 3 wire dryer cord, but the dryer wiring should be checked to see if it is three or four wire. I suggest you call some one who has knowledge of this or call an electrician out and have them check it for you. Electrical Contractor ||
- Q:What are the chemical properties of copper? A chemical property is a characteristic of a pure substance that describes its ability to change into a different substance. Examples of chemical properties include: new substances, new properties, flammability, and ability to react.
- I would call for help, that's the only thing, sorry. Bears run faster than humans, and they climb faster too, not to mention I have short legs. Don't think I can outrun a bear.
- Q:i have a project to do and i need a quote, saying or joke about copper. thanks in advance!
- Copper Sayings
- Q:So I am trying to find the amount of copper in a 10g brass sample. I first dissolved the brass in 6M nitric acid and then put it in a 250ml volumetric flask to make a copper solution. A 60ml aliquot was then taken of the solution and it was mixed with excessof 6M NaOH. This was then heated to form CuO + H20. It was filtered and left to dry. It was found that there was 3.05g of CuO.To find the amount of Copper in the original brass sample(of 10g) I did the following:Find percentage of Cu in CuO. Ar(Cu)/Mr(CuO) = 63.5/79.7 = 79.8%Mass of Cu in CuO precipitate: .798x3.05=2.43gMass of Cu in 250ml Solution: 2.43x(250/60)= 10.125gIs this the correct calculation procedure?There is obviously some error made in doing this experiment. What are some factors that could have led to this impossible percentage of copper in the brass sample when doing the experiment? (e.g spectator ions in the preciptate)
- dissolving brass (Cu + Zn) in HNO3 will produce a Cu 2+ and Zn 2+ solution. you cannot ignore the Zn 2+. everything that occurs to the Cu 2+ will occur to the Zn 2+. it will form Zn(OH)2 and ZnO with heat, etc. how can you be sure that you have a 'pure' Cu 2+ solution? 10 g alloy in 6M HNO3 --> Cu 2+ + NO3- + Zn 2+ as i said before, brass is made of copper and zinc. HNO3 reacts just as well with copper as it does with zinc. so, the zinc and copper ions will be in solution together. there is no way to separate the zinc from the copper with NaOH because both metals will form an insoluble hydroxide. you would be better off separating out the Cu with the addition of NaCl or KCll. CuCl2 would form and precipitate while ZnCl2 will remain aqueous. using NaOH does nothing to separate out the 2 metal ions.
- Q:What is the specific heat of liquid copper? All I know is that the specific heat of the solid copper is 390 J/kg*C
- That sounds right. Due to matalic bonds being to say the least a bit odd from a chemistry and quantum mechanics point of view metal atoms can vibrate more freely than you would expect from common sense. So all metals have a specific heat capacity that to me is surprisingly low. Also compare that to the 4200j/kgC for water which only weighs 1kg/litre! Strange but true
- Q:I did this experiment where we added copper strip to cyclohexane solution and another copper strip to water. In water it floated, but in sank in cyclohexane. WHY DID THIS HAPPEN?Something to do with intermolecular forces??Thankss :)
- The 1991 Pittsburgh Penguins and 1993 Montreal Canadiens decided to test its buoyancy by tossing it into Mario Lemieux's and Patrick Roy's respective pools (The Stanley Cup—noted then-Canadiens captain Guy Carbonneau—does not float.). Dominik Ha?ek had his visit with the Cup cut short for doing the same.
- Q:A 2.98g copper penny has a positive charge of 31.8uC. What fraction of its electrons has it lost? (Assume that natural copper has an atomic mass number of 63.5.)Thanks!
- Let's start by finding out how many electrons you would expect to find in a 2.98 gram copper penny, assuming all the atoms were electrically neutral. Copper is element 29 on the periodic table, so each neutral atom bears 29 electrons. 2.98 g x (1 mol Cu / 63.5 g Cu) x (29 mol e- / 1 mol Cu) x (6.022x10^23 e- / 1 mol e-) = 8.20x10^23 e- Now let's figure out how many electrons would have to be lost to give the penny a charge of 31.8 uC. Keep in mind that each electron has a charge of -1.60x10^-19 C, so the penny becomes that amount more positive for each electron lost. 31.8 uC = 31.8x10^-6 C 31.8x10^-6 C x (1 e- / 1.60x10^-19 C) = 1.99x10^14 electrons Now figure out what fraction of a penny's total electrons is represented by 1.99x10^14. 1.99x10^14 e- / 8.20x10^23 = 2.43x10^-10 or 0.000 000 000 243. Put another way, that means the penny only lost 1 out of every 4.12 billion electrons. I hope that helps. Good luck!
- Q:A mixture of copper(I) oxide and copper(II) oxide was found to contain 16.3% oxygen by mass. Calculate the mass percentage of copper(I) oxide in the mixture with two significant figures. Have an exam tomorrow and can't figure this out! I found the relative quantities of the two coppers by moles, but I don't know where to go from there...
- CuO (Copper(II) oxide) and Cu?O (Copper(I) oxide). This gives us a total of 2 oxygen atoms (1 in each compound) and 3 copper atoms. We are given that oxygen comprises 16.3% of the mixture's mass and since there is only one oxygen in each formula, it must constitute 8.15% of each compound's mass. Let's first assume we have 100-g of the mixture. That would give us 16.3 gram of oxygen and 100-16.3 = 83.7-g of copper. Let's start with the simpler formula CuO first. This contains equal numbers of moles of Cu and O. Since we know we have 8.15-g of O in it (8.15-g / 16.0-g/mol = 0.509 moles of oxygen) and thus 0.509 moles of Cu. 0.509 moles of Cu = 0.509 mol x 63.5-g/mol = 32.32-g of Cu in the CuO - Copper (II). Since we had a total copper of 83.7-g with 32.32-g of it in the CuO, there must be (83.7 - 32.32 = 51.38-g in the Cu?O - copper(I) . The total mass of the Copper(I) oxide is 51.38-g Cu + 8.15-g O = 59.53-g Given 100 grams of mixture and 59.53-g Cu?O we have a % mass of 59.53-g / 100-g x 100% = 59.53% = 60% to 2 sig fig.
- Q:i live in arkansas and we have had a a few weeks of triple didgets and i cant last another day without air conditioning our land lord will NOT fix it says to deal with it how can I fix it myself without a repair man??????
- Sometimes when they are getting low on freon this will happen. It could also be that you have much dirt clogging up the coils. Turn your air off and take a brush out there and try getting all the dirt off the outside of it. Hope this helps. I'm in MO. and it has been very hot! Hope this works and you get some relief.
- Q:I had a solution of salt water. Cathode was aluminum and the anode was a nickel plated coin. The aluminum was plated in a dark metal which might be nickel. There was also an insoluable orange substance produced at the anode. Was that copper from the nickel plated copper coin? What were the reactions going on here?
- Copper atoms go into solution at the anode: Cu ---> Cu2+ + 2e- Copper ions from the solution deposit on the cathode as copper atoms i.e. copper metal: Cu2+ + 2e- ---> Cu So no, you didn't create elemental copper, you just transferred it from the anode to the cathode.
