Q:I have one run of copper water pipe in my basement with a tonne of condensation on it . Why does that one get it and the rest don‘t and what can i do to fix it , (there is enough water cumming off of it to get my floor wet) the pipe runes from the cold cellar to the opposite side of the basement but the whole pipe is wet i have another pipe with the exact same run right beside it except it is 3/4 and it is bone dry.: yes all the way around. the cheap easy trick would be shock extensions but the tend to brake easilly. taller struts (if equipped) would raise it but throw the alignment out baddly and the fix can be very high dollar, the siplest answer is sell and purchase the taller car or SUV and you dont need to spend the bucks and have pease of mind as well

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.: rbtybwr

Q:when a 18.5g piece of copper originally at 99.5°C is placed in 58.5g of water at 24.0°C, the temperature of the water rises to 26.1°C. If the specific heat of water is 4.180J/(g.°C), calculate the specific heat of copper.Please help me. I tried using the specific heat formula ( specific heat=heat transferred/mass x temperature change). but, when I do it, it doesnt come out right. What am I doing wrong?: Don't know if I'm too late, but better late than never right? Anyway, you're doing it wrong because you aren't given the heat transfered for the copper. So your equation (specific heat=heat transferred/mass x temperature change) cannot work. Instead set up two equations, one for the water and one for the copper where the combined heat transferred is zero. Heat transferred for system = heat transferred for (copper + water) Q = m?c?ΔT? + m?c?ΔT? 0 = [(18.5)c?(-73.4)] + [(58.5)(4.180)(2.1)] 0 = -1357.9c? + 513.513 c? = -513.513 / -1357.9 c? = 0.378167 J/(g*°C) Specific heat of copper in solid form is about 0.385 J/(g*°C) according to Wikipedia. So this is pretty close.

Q:I have a new construction townhouse. Whenever I take a hot shower or require hot water upstairs I find that drawing any cold water from kitchen sink or refrigerator immediately after will result in a light thudding noise in the ceiling pipes. Is this just them expanding? Once you wait a while or run cold water in shower at the end there is no thud. Thank you!: problematic thing. look into with google. that will may help!

Q:my dumb *** totaled my vehicle so im now scrapping it since it wasnt insured im screwed. ive been told that copper is the best metal too scrap and i was wondering where in the vehicle would i find the majority of it i dont feel like ripping the whole car apart just too get a little extra out of it: Copper wires, radiator, battery, starter, gen, are the best things to take off to sale.

Q:I am 21 years old and i have the copper iud inserted about 16 months ago. For the past year or so my sex drive has decreased so much. I have 3 year old daughter and am married. I just want to know if anyone had had this or any side effect possibly caused by the iud. My husband and have concerted removing it.: Your copper IUD can't really do that, because it doesn't tamper with your hormones at all... The only way it could interfere with your sex drive would be if the device itself was causing apprehension for either you or your husband via pain or discomfort during intercourse. Otherwise, I don't think it's your IUD; there's nothing in it that would have that effect.

Q:I have some 24 guage wire, looks like copper but is a more red than the copper wire I have bought in my local hardware store. I have stored the two spools of wire in the same toolbox for 10+ years and the 24 guage wire did not tarnish or even changed in color at all. I have since used the 24 guage in my jewlery and I am looking for something similar. I have been to all of the mianstream hardware and craft stores and have not found any wire that will not tarnish or the color will not scratch off while working with it. I have looked on the net and have found tons of wire manufacturers with copper alloy wire, but do not know what copper alloy will not tarnish. Please help if you can.: Chances are your untarnished copper wire is clear-coated. You can do this yourself with a spray or brush-on varnish, best after the jewelery is made so it doesn't crack when bent. This is what many jewelers who work in copper use.

Q:The brass of 42 to 6.4 of each pipe diameter approximately every 100 meters?: Copper pipe is the best water supply pipeline.Copper tube (outer diameter thickness) * thickness *0.02796Brass tube (outer diameter thickness) * thickness *0.0267That's theoretical weight per meter.

Q:If I take Tri Sodium Phodphate (P2O5), Copper Sulphate (CuSO4) and Sodium Hydroxide (NaOH), than what would be the quantity to make stable Copper Hydroxide [Cu(OH)2].: Even though this is more of a chemistry question than an agriculture one... Copper(II) hydroxide can be produced by adding a small amount of sodium hydroxide to a dilute solution of copper(II) sulfate (CuSO4 · 5H2O). The precipitate produced in this manner, however, often contains an appreciable amount of sodium hydroxide impurity and a purer product can be attained if ammonium chloride is added to the solution beforehand. Alternatively, copper hydroxide is readily made by electrolysis of water (containing a little electrolyte such as sodium bicarbonate). A copper anode is used, often made from scrap copper.
