Q: I‘m making a copper-pipe xylophone for a school project, but all my pipes are one octave too high. Following the formulas I found online, I tried to calculate the lengths necessary for a C4 scale xylophone, but the resulting numbers were ridiculous (55 something inches for C4. T__T) Then, I tried buying thicker pipes to make the sounds lower, but was flabbergasted when the notes actually got higher.The pipes I have right now are 1/2 inch ones (the thinnest pipes in Home Depot. I think), in a C5 Major scale with measurements of 258 mm, 245 mm, 230.5 mm, 223 mm, 210.5 mm, 199 mm, 186.5 mm, and 181.5 mm. (C5, D5, E5, F5, G5, A5, B5, C6)I‘ve searched multiple sites and have not been able to find a solution to this problemo. ;__;Is there any way to alter each pipe that would made them go down an octave? Also, how would one determine the measurement for an F#? Please, please answer if you can; I need the project done by next Friday! lt;3 Thank you so much, I am eternally indebted to youuu!!!!!!!!!!!lt;3:D: If you close one end of each tube, you will get a resonant frequency of 1/2 what you would get if it were open ended. It drops about 1 octave.

Q: Chemistry Lab Limiting reactantelements used silver nitrate and copperBefore massing the copper we were told to sand it what is the purpose of this?: Sanding the copper would remove some of the oxides, and increase surface area, but it would not remove all of the surface contaminants and it would likely introduce new ones. I've never heard of sanding as a laboratory technique. If I wanted a corrosion-free copper surface with lots of surface area I would pickle the copper in acid and then rinse and store in deionized water.

Q: Copper is also used for pipes, but in the Roman times lead was used for plumbing. What makes both these materials suitable for this use? What makes lead unsuitable?: lead is poisonous substance where copper is not, both of them could be moulded or hammered in any shape which makes them suitable for making anything.

Q: What are these copper pipes in my attic?: Probably for heating, don't worry about them unless they have a liquid in them.

Q: Is there anything I can do w/o a plumber? I have the water turned off to the whole house and don't really want to leave it off until tomorrow.: Unless you can access the rear and plug off the supply pipe(s), you are gonna be without water until you get a plumber! Can't say for sure, but you are probably gonna lose some wall to gain access, so you could go ahead and open up the wall to get to the pipes. You could cut them off and solder caps, or even crimp the ends and solder if you are capable of that.

Q: Hi there, I wondering if anyone could come up with a reasonable answer and explanation for this question.Both copper and lead have been used to make water pipes. Which metal would be a better choice?: COPPER. Lead will result in lead poisoning and mental problems. Never use lead pipe for potable water. TexMav

Q: 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.

Q: There is a leak in the copper piping, and the solder won't stick. How do I fix this?: all the answers are correct here. your biggest problem will be draining ALL the water out of the system before replacing the problem fitting where the leak is occurring. i suggest using unions in case you have water problems.
