Q:is aluminium more ductile and malleable than copper?: Dear X, This is not an easy question. Pure Copper is soft, malleable and ductile. As it is worked and forced to change shape it Work Hardens and will break or crack unless it is heated to anneal it. Copper with oxygen impurity is also hard and does not conduct electricity well. Pure Aluminium is soft, malleable and ductile. It is alloyed with other metals to make it useful(Cu, Mg, Li). Certain alloys Age Harden so you can build an aircraft from soft aluminium and then it hardens and becomes strong. If the Al sheets are in store too long they harden and become brittle and must be sent back to the factory to be re-softened before they can be used. I hope this is useful:Rufus

Q:Hey guys. I was doing an experiment in which I made some copper acetate. I took copper sulfate and had it react with sodium hydroxide to make copper hydroxide and had that react with acetic acid to make copper acetate. Now I have a few questions. When I added the copper hydroxide to the acetic acid, the solution turned black.: I guess you added the copper hydroxide to hot ethanoic acid...if so the black solid was probably copper(II) oxide. When making a salt by this method you should always add excess solid to ensure there is no remaining acid, then filter off the excess when reaction is complete. This ensures the salt formed will be in a simple aqueous solution. Allow this solution to deposit crystals by standing in a warm environment for a few days - then remove, rinse and dry the crystals. Copper ethanoate is not very soluble so it should crystallise out quite quickly. If you heat too rapidly you could get a mixture of the dihydrate and the anhydrous compound: they would have differing appearances. P.S. Copper(II) ethanoate has an interesting, 'dimeric', structure, a bit like that of chromium(II) ethanoate that used to feature at A-Level in the UK.

Q:Hello,I am getting an iPod classic, and with that, a pair of headphones. The thing is, I'm trying to decide between the IE2 Bose and the Monster Turbine Pro Copper.. So, if anybody could fill me in on which is better, based on what they've used or heard, I would be grateful. Thank you!: I would go for Monster Turbine Pro Copper These phones are quite good and deserve the praise they are getting. The key word to describing the MTPC's sound signature and quality is balance. Unlike just about any other earphone I have had the pleasure of listening to, the MTPC, though focused on bass, does not fall tremendously short in any one area. The magnificent soundstage and imaging with a wonderful musicality made listening to the MTPC was a very enjoyable experience. If you want netrality or absolute bass monsters then you better do some more research because these are not it but they are somewhere in between. These phones have warmth, balance, great mids, smoothness and a whole lot of fun. The best part about these phones is that it does not stand to be intimidated. You can throw whatever you want at it and it won't blink twice. Trance, rock, pop, country, whatever the Coppers handle them just fine. With that kind of versatility to go along with a popular signature I have no doube that these will be liked by many. okorder: Monster Turbine PRO High-Performance In-Ear Speakers (Copper) amzn.to/f991Ap ......................... Anyway, if the price does matter, Bose IE2 is a good set of earphones for the price. Bose? IE2 audio headphones' by BOSE amzn.to/gOCCpV

Q:normally use regular methods and a mapp torch on 1/2 pipe. Curious if it‘s worth using the combo flux and solder to speed things up in tight areas.: Solder paste is made up of microscopic balls of solder suspended in a thick flux. It has the appearance of gray or silver cake frosting, and sometimes has an of yellow tint from the flux. I am not a plumber and I have never used this on pipes. Frankly I did not know it was available for the purpose. I have used the lead based version of this product for more industrial applications. It is potentially very dangerous. The problem is the microscopic balls. Once freed from the flux, usually by washing, these little buggers are so small you can't really see them with the naked eye. They will embed them selves into pours and fingerprints, and contaminate every thing you touch. Additionally once in the body the small size makes them easy to digest and absorb into the blood stream. We had a heck of a time cleaning these nasty little bugger up, and the mandatory blood test were no fun ether. Again, I want to point out that my experience was with led based solder paste, not a silver based solder paste. If you have a led based solder paste, please consider turning it in to your local hazardous waste facility. If you have a silver based solder paste, I don't know if there are any health ramifications from digesting it, but you will probably end up digesting some minute amount of it now matter how careful you are. Just because there are so many of those little balls waiting to start rolling around and sticking to things.

Q:I have a leak in a copper pipe embedded in concrete in my wall. The leak is 100% inacessible.My 1st Question is:Can I repair the leak from the inside of the pipe? I think there may be some chemical or resin on the market that can be flushed through the pipe to plug the hole.My 2nd question is:Does anyone out there have experience using such a product was it successful?Thanks everyone.: hi maybe if you can run a plastic tube inside the copper pipe and modify the ends to connect ???

Q:Element Copper. How does copper make the world better? and also where do you find copper?: Copper is used in pipes and wires. It doesn't poison us like lead pipes and it's a better conductor than Aluminum wires. The best place to find copper is to rip out the pipes from an old abandoned building. Be sure to do this at night so nobody will catch you. If you're rich you can buy it at Home Depot or Lowes.

Q:I did attach the (i hope) water line.: Smog is correct. The ice maker could care less how the water gets to it. The saddle valve is just a quick and cheap way to do it when there is no T installed in the water lines somewhere.
