Q: I have to replace copper piping with a flex line in order for home depot to be able to install a dishwasher. can anyone walk me thru this? thanks, i need to do this by Tuesday.
you should be able to get a breaded dishwasher supply line from home depot to go to it just make sure its the right size thats if your replacing an old one
Q: I needed to replace the thermal fuse in my dryer and when I pulled the dryer out I noticed a bad kink in the 3/8 copper tubing near the connection to the dryer. Here in MN it is very common to use copper for natural gas appliances.My question is, can I simply re-flare my copper end and connect it back up just like it was? I am reading a lot about these flex pipe installation kits I really don‘t want to spend the money on something I don‘t need.OK to just connect it back up like it was?
If you know what you are doing, then yes, remove the kinked section of copper line and flare both ends and connect with a inline copper connector. Test with a soap and water solution after making connection. Remember, this is nothing to fool around with. If you are not 100% sure, then hire a pro.
Q: Single replacement reaction for Copper and Zincate ions.- Not sure if I remember how to do correctly, did it acouple years ago.
According to one website, zincate ions form in basic solution: CHEMICAL PLATING OF A PENNY In this experiment, we will observe the plating of one metal with another by chemical means. We will plate zinc on the copper of a penny, which is just the opposite of what we normally would expect to happen. We know from our study of ions that the Zn++ ion combines with two OH- ions to form zinc hydroxide Zn(OH)2. However, in the presence of sodium hydroxide NaOH, zinc will combine to form the complex ion known as a zincate ion. [Zn(OH)4] - - or [Zn(OH)3 * H2O] - it is this zincate ion which allows zinc to plate on copper. Another website that provides a lab procedure for zinc plating pennies explains the formation of zincate ions in the following way: In this reaction, zinc dissolves in the hot concentrated sodium hydroxide solution to form sodium zincate, commonly written as Na2ZnO2, or, as obtained in solid form from concentrated solutions, NaZn(OH)3. As an ionic equation this can be written: Zn + 2 OH- --> ZnO22- + H2 None of these websites mention single replacement reactions for copper and zincate ions.
Q: I started a tank in my college dorm. Cycled the tank, acclimated the fish, everything. 5 of my 7 corydoras (all that was in the 10 gal) died. I immediately removed them once I realized there was a problem. Two of them died in the toxic waters and 3 of them died in my SAFE 20 gal at my house; 2 of them survived :) I would like to start up the 10 gal for my brother in his room at the house with same water in the 20 gal. I discovered that the pipes in my dorm are copper pipes and the water was full of copper and poisoned all my fish. Therefore, they all died from copper poisoning :( My question is how should I clean the tank? I removed the gravel and got all new gravel (obviously removed all the water). but the filters, are they safe to use if I change out the cartridge. What about the ornaments; they aren‘t very big and have a sealant on them. I just don‘t want to end up poisoning other hopeless fish. Thanks for your help
Interesting conclusion. Copper waterpipes are standard in much of europe and yet we don't get copper poisoning. I got copper pipes in my house and I'm breeding 2 species of shrimp and we all know how sensitive those are to copper. Anyway, if it was copper poisoning yes you'd need to replace filter media and recycle the tank
Q: hi, i need help with my chemistry homework and i cant find this anywere, its in for tomorrow so please get your answers in a.s.a.pHow is copper obtained from low grade ores?also what is the definition of Reduction with carbon? thanks
generally speaking, copper and many other base metals are processed in a very similar fashion. The raw ore is crushed into small bits and processed to concentrate the metal minerals. This is called density separation; metal ore minerals tend to be of much higher density than the gangue (the non-value minerals). There are also chemical ways of producing a concentrate of ore minerals The concentrate is then sent to a smelter where it is melted. Since most metal ores see the metal in minerals under an oxidized form (as a cation), the metal must be reduced. Commonly this is done in the presence of carbon, the carbon reduces the metal cation to the neutral elemental form (the carbon is oxidized in its turn to CO2). Reduction by carbon means that the metal gets electrons from the carbon, changing the metal's charge state from positive to neutral. During smelting, a very rich metal product is formed that can be separated physically (usually as a liquid) from the gangue residues, which are now called slag (waste rock from smelting). Many metals, copper among them, also undergo an additional step of purification involving electricity. The raw ore, which is fairly pure but not super pure, is placed in an acid or salt bath and electricity is put intot he system to create what is basically a reverse battery. The copper dissolves off the side with impure copper and collects as a very pure copper on the other side of the bath.
Q: The pipe runs under the house alongside a few others. A few months ago it developed a crack or something and started leaking. I cut out the bad part of the pipe (like 15 or so) and installed a new one with compression fittings. Now, 2-3 months later the same pipe is leaking like 2 feet from the old crack. And there are no joints or anything - seems like cracks develop in the pipe for some reason.I‘m afraid that if I fix this one, a new one might appear in some new spot. Could it be some defective pipe? Or is it touching something that makes it corrode or something?Please help.
I'm guessing the pipe is aged. Over the years the pipe will thin out starting from the inside. More so if its a drain pipe due to the chemicals that have been washed through it over the years. You may need to cut out that whole section, replace with new.
Q: I came across some [maybe] copper printings of 1880s San Francisco. I'm wondering who made them, how, why, and what they might be worth.Help?
Copper printings? Do you mean a copper etching? Is the image etched into the copper? Look for a signature or initials. That will determine who made them and if they're worth anything.
Q: Refrigerator freezer room, the middle drawer, the back wall has 1cm copper tube naked leak, what's the matter? Why naked leak?
Normal, now generally use the refrigerator evaporator aluminum coil, on the back wall of the pipeline and the evaporator joint part is copper, so generally have a little bare can see on the outside, the rest of the line is actually a lot of refrigerator also can see, but mostly due to aluminum, and the rest of the evaporator is not much difference, so you don't pay attention. Bare for no reason, because the pipe from the back wall of the refrigerator, to connect to the top of each drawer evaporator coil, must be exposed, the low-end low-end refrigerator, there is no need for beautiful design occlusion or hidden.
Q: What is the connection between the air conditioning tubes?
Connection method for air conditioner copper tube(1) air conditioning copper pipe connection, remove burrs and dirt in the pipe section, tube card, ring is sleeved on the outer wall of the pipe, the pipe thread interface, the snap ring is tightly pressed on the outer surface of the copper tube and the tube surface finish is tightly connected to the brass cut, cut burr, clean, use special expanding forming tools, expanding export processing into a cup or cone;(2) when connecting, the end of the cup or taper pipe is pressed into the copper pipe piece, the cup shaped or the conical outer surface by the screw thread interface of the copper pipe piece, and the pipe sleeve nut is locked to complete the tight connection;(3) the air conditioning copper pipe connection is directly processed into flanging pipe fittings: the copper pipe port adopts a special machine or a hand flanging tool, and is processed into flanging flanges. Through the steel flange connecting bolts complete implementation, tight connection, with a lower melting point than the timber and timber solder heating, in the material is not melted, melting, filling the gap between the joint of two materials, complete the brazing seam.
