Q: Anyone have any ups or downs on copper bottom pans? I'm debating between stainless steel with copper bottom or copper bottom with teflon.. any suggestions?: Heating with copper is nice; they heat more evenly and get warmer faster. The down side is that they need extra care. Copper tarnishes easily and stains like nobody's business. So if you want your pans to work well all the time, you must be prepared to maintain them.

Q: I'm 30 and considering getting off the hormonal birth control. I'm interested in the copper iud. However I keep reading post of women who claim they had gained weight. I just don't seem to understand how. Since the IUD doesn't release any hormones? Has anyone experience weight gain due to the Copper IUD?: The Copper IUD won't make you gain weight. People who gained weight on the copper iud would have gained it anyway and they are just blaming the iud. Women often gain weight as they get older. Women also tend to gain weight when they move in with someone or get married, events that may have occurred around the same time as the IUD insertion. IUDs are also commonly put in new mothers who, instead of loosing their baby weight, may put more weight on due to the stress of being a new mother.

Q: Because copper's oxidation number is 2, and Sulfur's is 6, what does this tell you about the reaction they would make when heated together? What drew you to this conclusion? Thanks. :): Copper is a metal and can lose 2 electrons to give the Cu+2 cation. Sulfur is a non-metal and can gain 2 electrons to give the S-2 anion. The compound formed is CuS.

Q: why is copper (ii) nitrate blue? - is it the copper ions?and why is potassium chromate yellow?please link to a website if you can cuase i have to site a source: Copper(II) nitrate is the chemical compound with the formula Cu(NO3)2. Commonly referred to simply as copper nitrate, the anhydrous form is a blue, crystalline solid. Hydrated forms of copper nitrate, also blue, are commonly used in school laboratories to demonstrate chemical voltaic cell reactions.

Q: I'm replumbing a house I just bought, and I'm trying to decide what material to use. I am on a pretty tight budget, and the house is not in the best neighborhood (the copper plumbing was stolen). What are the advantages and disadvantages of each? Are there any carcinogens I should be worried about with the plastics?: Hi, 'Guy. First and foremost, check to see what's code for your town. Copper will always be acceptable. CPVC (for hot and cold lines), may be but possibly only for repairs by a homeowner. Note that PVC is not rated for hot water supply. PEX is the most modern, quick with proper system fittings, and fine with both hot and cold piping - but may not (yet) be code-approved where you are. And do not get it confused with PB (gray) plastic pipe on advice from others - it's gone, gone, gone. Backing up to the loss: I'm guessing that the theft happened when the building was unoccupied, perhaps even why you bought the place as is at a good price. The overall security needs at least some attention, like cutting back bushes, motion sensor lighting outside, possibly adding an alarm system, etc. If working there in the day, then going elsewhere for the nights until it's done, leaving a big ol' loud dog inside is gold. Meth heads do not like being freaked out or bit. I'd go with copper, but check out PEX if it's approved there. And - inspection requirements?

Q: Which statement best answers the question, &quot;Why is copper a good conductor of electricity?&quot;?AnswerA.Copper atoms have a loosely held electron in their outer shell that is able to move freely to other atoms.b.Copper atoms are tightly bound and are able to work with other copper atoms to exchange electrical charges.C.Copper has an equal number of protons and electrons making the flow of current possible.D.Copper's outer shell electrons are not balanced and must join with other copper atoms in order to be stable.I know it's either A or B I just don't know which one. Please help?: Copper is a ductile, semi-precious metal with very high thermal and electrical conductivity. Pure copper is soft and malleable; an exposed surface has a reddish-orange tarnish. It is used as a conductor of heat and electricity, a building material, and a constituent of various metal alloys. The major applications of copper are in electrical wires (60%), roofing and plumbing (20%) and industrial machinery (15%). Copper is mostly used as a metal, but when a higher hardness is required it is combined with other elements to make an alloy (5% of total use) such as brass and bronze. A small part of copper supply is used in production of compounds for nutritional supplements and fungicides in agriculture. Machining of copper is possible, although it is usually necessary to use an alloy for intricate parts to get good machinability characteristics. The atomic number of copper is 29, which means it has 29 protons in the middle and 29 electrons moving around the outside. (The 29 negative charges of the electrons and the 29 positive charges of the protons balance out, so the atom is neutral when all of its electrons are in place.) Copper has two electrons in the innermost shell, eight in the next shell, eighteen in the third shell, and one in the fourth shell. This means that the first three shells each have as many electrons as they can hold, and the fourth shell has one lonely electron. (The fourth shell can hold up to 32 electrons.) Because this one lonely electron is all by itself in the outer shell, it can easily separate from the rest of the atom and go roaming around, which makes copper a very good conductor.

Q: i‘m installing copper pipes to my bathroom and i know that the standard size to supply water to faucets and showers is a half inch. but would spending a little more now and getting 3/4 inch pipes be better in any way or just a waste of money and water? the reason that i ask this is because when i look at the inside of my old pipes (galvenized), there is barely any room left from all the mineral or whatever build up. that‘s why i was thinking if i were to install larger pipes now, wouldn‘t that increase the life of my pipes? does copper pipes even get build up like iron? what exactly happens to copper pipes after 40-50 yrs. (i‘m told that‘s the average life).: its common to use 3/4 as in comes into your home after that you take off 1/2 to furnish the rest of the house.you will not get a build up with copper .as with galvenized because of a chemical reaction that takes place in the lines over time as minerals react with the galv.not so with copper. 65

Q: Since 1982 pennies have been made of zinc plated with a thin layer of copper. The modern penny weighs 2.500g, has a diameter of 19.05 milliliters and an average thickness of 1.224 milliliters. Given that the density of copper is 8.96 g/cm^3 and the density of zinc is 7.13 g/cm^3, determine the percentage by mass of copper in a modern penny.: Density = Mass / Volume The penny's volume = pi x r^2 x h radius = diameter / 2 = 19.05 / 2 millimetres = 9.525 millimetres = 0.9525 centimetres height = thickness = 1.224 millimetres = 0.1224 centimetres = 3.142 x 0.9525^2 x 0.1224 = 0.3489 cm^3 Overall density of penny = 2.500 / 0.3489 = 7.165 g / cm^3 7.165 x 100% of penny's weight = 7.13 x (% of zinc in penny) + 8.96 x (% of copper in penny) % of zinc in penny + % of copper in penny = 100 therefore % of zinc in penny = 100 - % of copper in penny therefore 7.165 x 100% of penny's weight = 7.13 x (100 - % of copper in penny) + 8.96 x (% of copper in penny) let % of copper in penny = A therefore 7.165 x 100 = 7.13 x (100 - A) + 8.96 x A 716.5 = 713 - 7.13A + 8.96A 3.5 = 1.83A, therefore A = 3.5 / 1.83 = 1.91% copper Total weight of penny = 2.5 grams Total proportion of copper in the penny = 2.5 grams x 1.91 / 100 = 0.04775 grams
