Q: Properties of Copper? what are they PLease explain the properties of Copper! x I REALLY NEED HELP: Physical properties: Copper is a metal with a distinct reddish or orange tint, with a metallic luster. The cubic crystalline structure is face-centered, and reflects only red and orange colored light from the visible spectrum, giving it the familiar reddish hue. Compared to adjacent metals in the periodic table, copper is harder than zinc but softer than iron. The metal is malleable, meaning that it can be elongated with pressure and molded into different shapes. Copper is also ductile, which enables it to change form and be stretched into long thin structures without breaking. These properties, along with its ability to conduct electricity extremely well, make copper suitable for use in electrical cable manufacturing, where these physical attributes are particularly desirable. Chemical properties: The atomic number of copper used in wires is 29, meaning it has 29 protons. Copper's symbol is Cu, and its atomic weight is 63.54. Copper is placed in column 1B in the periodic table, along with silver and gold, whose symbols are Ag and Au, respectively. Copper has a Moh's hardness (a system of measurement to evaluate the hardness of metals) of between 2.5 and 3. Copper used in manufacturing wires has a very high specific gravity of 8.2, which is much higher than other substances of industrial interest, such as water (1.0), carbon (2.2) and sulfur (2.1). The specific densities of silver and gold are both higher than copper, at 10.5 and 19, respectively. Copper wires have low chemical reactivity; in reaction with other elements, laboratory copper has a charge of +1, known as cuprous or +2, known as cupric. Corrosion: Copper in electrical wires is resistant to corrosion. When exposed to damp air, the substance changes color from reddish orange to reddish brown. In time, a fine greenish film, known as patina, coats the surface of the metal, protecting it from degradation through corrosion.

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: Suggest reasons for using copper rather than another metal, such as lead, zinc, and iron?: lead gets into the water, copper wont rust, i am not sure about zinc or iron but cost and workability may factor in.

Q: I have a tub spout htat is just roached and i need to replace it badly. The problem is.the old spout is about 40 yrs old and coneected way inside.the one I need to install has the threaded portion right at the end of the tube. unfortunately it is not an option to rip out the tile and replace entire tube. Is there a way to cut and rethread the tube w/o opening the wall and removing the tube? Thanks!: you do not need to thread a pipe. There are pipe ends that are already threaded. you can solder it to a length of copper pipe and then install that into the diverter. Leave it the pipe long then you can measure how much you need sticking out of the wall and cut it accordingly with a tubing cutter. Solder another threaded end onto that and install your spout. Make sure you use teflon dope tape on all threaded connections.

Q: I think taurus makes a solid copper hand gun bullet and maybe one or two other companies do as well. The reviews are great.: Why? A pure copper bullet has less mass than a lead one or a copper jacketed lead one. I want MORE mass, as much as possible. I also want a soft, expandable center, not a hard one. I think any advantage is a matter of Marketing and Salesmanship than good ballistic science...........remember the gun mag writers are on the payroll of the gun and ammo companies.

Q: Is it normal for air to leak out of a copper pipe on a refrigerator?: I would never pay $20 for 1 blade, that is a rip off!! You can get michelin, anco and rainx blades for less than half that price.

Q: I'm pretty sure I just got a copper quarter for change from the airport. It's year is 1981. How much could it be worth? How do I clean it to make sure it's not just rusted without damaging it or reducing the value?: It is more likely a quarter that had been in water or has other environmental damage. In order to be a copper quarter the outside layers would have to been missed when the blank was made. It then would be real thin and weigh a lot less than 5.67 grams of a normal quarter. Cleaning it would damage it more, for it is damage in the first place.

Q: im trying to attach aluminum 1 inch fins to a copper pipe (radiator heater pipe). (dont ask). im trying to find the best glue to do that. i think i can use epoxy to do that.any other suggestions ?: Copper and aluminum form a bond that when it gets wet will cause the aluminum to disintegrate. This is called electrolysis. If you have any choices, use copper fins, as a second choice aluminum pipe as an alternative. Aluminum has a very poor coefficient of heat. JB weld will work.

Q: I have a lot of copper and I need money so I was gonna scrap it tomorrow so I need to know how much I can get copper scraps for per pound.: Depending on the grade of copper you can expect different pricing. See some basic price ranges below: No.1 Heavy Scrap Copper 1.12 1.27 lbs USD No.2 Scrap Copper 0.98 1.13 lbs USD Soldered Copper Pipe Scrap 0.84 0.99 lbs USD Light Scrap Copper 0.84 0.99 lbs USD No.1 Bare Bright Copper Wire 1.15 1.30 lbs USD No.1 Copper Wire Scrap 1.09 1.24 lbs USD No.2 Copper Wire Scrap 0.98 1.13 lbs USD No.1 Insulated Copper Wire 0.45 0.70 lbs USD

Q: Is the connecting pipe of the air conditioner copper tube or brass tube?: Brass, because the use of relatively long time, contact with refrigerant, chemical reaction, looked like copper.
