Q:Separate copper remover necessary for WWB JHP?
Well yes copper is deposited in the rifling on firing,
Q:Copper Tubing needs rounded...Tool used?
never seen egg shaped copper tubing
Q:A bottle of mineral supplement tablets contains 100 tablets and 200 mg of copper...?
Cupric oxide = CuO 200 mg copper = .2 grams copper molar mass of copper = 63.54. .2/63.54 = 0.0031476235442241107963487566887 moles of Cu molar mass of CuO = 79.54. Moles of Cu = Moles CuO 79.54 * molar mass = 0.25036197670758577274158010696352 In other words, about 250 milligrams of CUPRIC OXIDE. If the 200 mg of copper is per tablet, my answer is per tablet. If it's 200 mg per bottle, the answer is 2.5 mg per tablet.
Q:Is copper....?
Zinc carbon battery? Lead acid battery Ni-MH (Nickel - Metal Hydride) Ni-Cd (Nickel Cadmium) LIthium ion? do you see copper mentioned?
Q:Which metal works best in making a lemon battery, zinc, steel and copper?
Zinc and Copper - More electrically conductive than the other 2 options. Steel is usually used as an electrical conductor when there are mechanical forces at play that could lead to structural fatigue since it is a stronger metal (like in cars or airplanes, or in buildings to resist rats chewing through it). For a stationary project like this, Zinc and Copper.
Q:been working on copper pipes plumbing?
Sorry but teflon tape is the industry standard and works great when properly used. You may be over tightening or one of the fittings could be slightly out of round, either would cause your problem.
Q:Can i melt small copper wires with candles?
If you want
Q:Will this be a cautioning amount of copper exposure?
Copper needs to be in contact with your skin to be absorbed. Copper bracelets are a popular item. Don't worry about copper hair holders. They're harmless. You should be more worried about the EM field in your cellphone, pressed against your ear. Those can cause brain cancer.
Q:Copper (II) sulfate + steel or zinc?
Copper ions in solution are blue. If you add steel(iron) or zinc to a copper sulfate solution, the copper ions will take electrons off (oxidize) the more reactive metal, and become copper metal (coating the iron or zinc, and/or precipitating to the bottom of the solution) and as this metal displacement reaction proceeds, the blueness of the copper sulfate solution will fade, as there will be fewer Cu2+ ions remaining in the solution.
Q:How do you protect a copper top roof above a bay window?
A packet of unsweetened kool-aid will do the trick. Mix it up with 1/2 the water recommened and use a green scrub pad like the one you use for dish washing. Personally i like the way copper turns, the green is tell tale of the copper underneath.
