- Q:So I want to find a really great, unique copper ring to have something inscribed on. I know exactly what I want, only problem is I don't know anything about copper jewelry, do you? AND, I need to know a really great website or something to find copper rings on. Hopefully there are some experts out there stumbling across this!

- Q:Haier air conditioning 1.5P, 3P, 5P, 3P Guiji, copper tube diameter, thank you heroes to the solution
- 5P brass is 200 yuan per meter, the other I don't know what Haier charges ~ ~ ~ ~ charge according to local prevail, if you feel your receipt, please put the installation master ~
- Q:WHAT IS COPPER'S HARDNESS/MALLEBILITY (hardness)???????? plz!
- Copper hardness is from 2.5-3 on the Mohs Scale (geologist's scale of measuring hardness). That hardness is associated with the definitive mineral Calcite, which can be colloquially measured against a standard fingernail. There is no actual value that measures malleability (no 1 - 10 or anything like that). However, copper is definitely malleable. Material can be qualified as brittle, malleable, ductile, elastic, or sectile. Copper is malleable.
- Q:Describe and explain how electrolysis is used to make pure copper from a lump of impure copper.
- they stick a lump of impure copper into an aqueous solution, and run an electric current thru it so that the impure copper releases Cu ions into the water (reduction reaction, at cathode) and at the other end the Cu ions form a solid Cu by the oxidation reaction. i know that didnt make much sense or sound very technical but that's the basic basics of it.. im pretty sure.
- Q:^x = Small number that signifies the quantity of an element. Copper (Cu) + Sulfuric Acid (H^2SO^4) -> ?Would it make - CuSO^4 + H^2?If it helps I know that SO^4 is a negative 2 charge, and Cu is in the centre of the periodic table (which I think means it can react with anything).
- You are correct. Cu is a metal so will react with an acid to form H2 and the ionic compound between copper and the sulfate ion. In the formula you have written, Cu has a 2+ charge. Cu can also have a 1+ charge, and then the formula would be Cu2SO4, but for this reaction, the 2+ charge is most probable, so you are exactly correct. The copper II sulfate would be a very pretty blue in the water solution containing the product.

- Q:copper oxide + sulfuric acid > copper sulfateBut copper oxide doesn't contain OH ions??? Then how can it neutralize H ions??
- See my previous answer.
- Q:I need to know what the chemical equation for electroplating copper onto quarters is... first right answer 10 points
- The electroplating of copper in high-aspect-ratio trenches and vias is a difficult challenge facing the new technology of copper on-chip interconnect. Super filling or bottom-up filling is currently achieved by the addition of organic additives to the electrolyte. However, the monitoring and control of additives in the electrolyte are difficult tasks, thus an additive-free electrolyte is highly desirable. Bottom-up electroplating can be achieved by stabilizing an intermediate species and reducing it in two steps, thus forcing the electroplating towards the bottom of the trench. A mathematical model is presented, which determines the conditions under which bottom-up electroplating occurs. Experimental results of bottom up filling of high aspect ratio trenches and vias are then presented from additive-free electrolytes
- Q:what dissolves copper so i can take this wire i got and use it for source of copper to plate on to a solid wire of copper? trying to make a bunch of copper wire in to a solid copper wire without attempting to melt in down instead i would like to dissolve it in some sort of acid maybe then use electricity to plate it to a solide wire
- Nitric acid will dissolve copper (the reaction will generate various nitrogen oxides (NOx), which are very toxic if inhaled). But a better way to make a plating solution is with a copper salt dissolved in sulfuric acid. This process is used to purify copper after smelting from ore. Put the copper source as the positive electrode (anode) and the object you want to plate at the negative electrode (cathode). Copper(II) sulfate is the most common salt used for this, and is probably the most readily available copper salt. Look for it at a pottery supply store or buy it online. You could also try heating the copper in concentrated sulfuric acid until the solution turns blue - hot sulfuric acid will dissolve copper.
- Q:Central air-conditioning is not the thicker the better?
- Air conditioning copper pipe must be able to withstand some pressure, because there is pressure difference inside and outside the pipe, not the thicker the better. More than the pressure requirements, and the pursuit of pipe wall thickness, waste materials, financial resources.
