Q:Why doesn't Copper wire dissolve in HCl like Al or Mg?
Copper is lower in the electrochemical series than Al & Mg Cu++ + 2e- = Cu Eº = 0.34 volt Mg++ + 2e- = Mg = -2.36V Al+++ + 3e- =Al = -1.66 V H+ + e- + 1/2H2 = 0 V (by defn) i.e. electrode potential has to be less than hydrogen - i.e. negative
Q:Chemical Reaction of Copper?
A little vague. Perhaps you are talking about the copper cycle lab. We can see that the reactions go to completion because there is a distinct change between reactants and products. Cu and nitric acid. There is no copper metal left. Instead we get a blue solution, Cu(NO3)2. Cu(NO3)2 and NaOH. There is the formation of a blue precipitate, Cu(OH)2. Cu(OH)2 decomposes. There is no blue solid remaining. Instead it has turned black, forming CuO. CuO and H2SO4. There is no black solid, but instead a blue solution of CuSO4. CuSO4 and Zn. The blue in the solution disappears indicating that there is no copper ion left in solution. Instead we see copper metal, Cu.
Q:Physical and Chemical Properties of Copper?
copper is a mineral it forms naturally in the earth. it's in the earths crust as an elementle form. it is a mineral found in deposits called ores.an ore is a mineral rich rock. they form during sedimentary,igneous, or metamorpic rock cycle changes. they are literal veins in the earth when hot underground water magma is cooled some ores are formed settled and hardened into mineral. thats how you get the physical property. the chemical property of copper is mined and made into copper wire, like alluminum, coal and oil. they are all natural resources made into everyday materials from the enviroment
Q:What do you know about zinc and copper?
Pure copper has a - well - coppery color. I believe zinc is a dull grey (it is used as the interior metal of many coins). When combined in an alloy, it's called brass. Depending on how much of each, it can look like a slightly yellowy copper or it can look green. When the metals are drawn into a wire, they should be straight. Curly wire happens when there is a defect in the drawing process. The degree of brittleness or maleability depends on whether it's been annealed or not. Annealing is a process of heating, then rapidly cooling the metal. With copper especially, if there is oxygen present during the heating, the oxygen will combine with the copper just as oxygen combined with iron creates rust. It degrades the metals maleability and electrical conductivity. Copper is somewhat common, currently mined in the Great Lakes area and in the Southwest US as well as other locations throughout the world. I don't know how to describe the smell as my sense of smell isn't too good (don't take up smoking!). As far as your last question, are you joking? Two ounces of each weighs exactly two ounces.
Q:Why aren't they using copper for oil clean up Apparatus?
If the copper starts out cold, it'll tend to stay cold -- for a while. For the ice bucket to work as desired, it should be cooled before the ice is added. If the copper starts out warm, it'll tend to stay warm -- for a while. Copper doesn't generate heat, it just stores it. It wouldn't take very long for warm copper lowered to the bottom of the gulf to cool to the same temp as its surroundings. Maybe copper would stay warm for a few minutes longer than some other metals but that would be the end of the affect.
Q:Copper based bullion bar useless?
Gold copper alloys are red in color, often referred to as Rose gold or Tumbaga gold. Usually silver and copper are used in equal parts to make yellow gold alloy. If alloyed with silver alone, the gold alloy will be green in appearance. White gold is gold alloyed with Nickel or palladium. Other colors such as blue and purple are possible with other metals but are brittle yet they are useful in inlaid jewelry. Black gold is based on an oxidation layer which is dependent on the base metal alloyed with and the coloration only exists at the surface. If the gold content is 99.9% then it's considered 24k gold though some countries will allow 99.0% gold to be called 24k gold. Gold is almost never available pure as it would be too soft. Most gold alloys will be gold, silver, copper and a little bit of zinc to harden the alloy, equal parts of silver and copper gives the alloy the appearance people expect of gold. The value of the bullion bar will be based on it's gold content. You should be able to determine it by measuring it's specific gravity. Weighing it in air and weighing it in water. Take it to a coin dealer if you want an authoritative opinion of it's value.

Q:Is a two crowns King Henry VIII copper coin have any value?
It's not a coin. It's a private-issue copper 'round' sold either as a collectible or to the naive person that thinks they're making a smart investment in copper. All 'AOCS Approved' means is that the American Open Currency Standard, a private company that promotes the idea of people making their own currency and bartering with it amongst like-minded individuals, has agreed to the use of their name. In my mind, it's not worth much, because one Troy ounce of copper - what this probably is - contains roughly 25 cents in pure copper. I wouldn't trade you a US quarter for it, because I can use that quarter towards buying something anywhere. It would take me a long time to find someone who would give me more than 75% of the bullion value, assuming they even were interested in a single round. Most places that buy copper buy it by the many, many pounds. It probably has more value as something to collect. Maybe up to $5 to the right collector.
Q:the value of copper pieces?
Phone wires are relatively small gauge wire, the run from the telephone pole from your house is proably 18 gauge wire, so a 100 foot run of 1 pair cable would have abount 1 pound of copper. This is worth around $3 when recycled. Transformers are worth less per pound because there is so much non-copper content, probably only about 66% copper, and phone related transformers tend to be small -- an 8 ounce transformer (which is likely heavier than anything in your home phone system) would probably yield around $1 when recycled. Your residential phone wiring inside the house is smaller than the wiring the phone company uses, 100 feet of 4 pair 22 gauge wire would weigh around 1 pound and be worth around $1. It seems like very low payback for the amount of work that is required and the risk from prosecution, but I suppose if someone is desparate for money, they'll take the risk. More commonly, power cables are stolen for profit, 100 feet of 3 conductor 14 gauge home wiring is going to weigh 3 lbs ($9) - and 100 feet of 3 conductor 10 gauge wiring used for something like a streetlight would weigh around 9 lbs ($27)
