Q:welding copper sheet together?
Thin Copper Sheet
Q:19.05 air conditioner copper tube, multiple meters per meter
Vibration hose has several specifications to see thickness
Q:Mass of Copper?
First you need to find the percentage of the mass of copper (ii) chloride dihydrate that is only copper. This can be found with the molecular/atomic weights. Cu - 63.54 Cl - 35.453 * 2 = 70.906 H2O - 18 * 2 = 36 Total for the mixture = 170.446 % Cu = 37.28% Mass Cu = 0.7456 g Cu cannot be created nor destroyed and Cu does not appear anywhere in the products except as elemental Cu. The answer should be 0.7456 g.
Q:Is Cu5O4 a form of copper oxide?
Copper forms two oxides Copper(I) oxide (cuprous oxide, Cu2O), a red powder; and Copper(II) oxide (cupric oxide, CuO), a black powder. This is because copper can donate either one or two electrons. What you probably got is a mixture of the two with 25% cuprous oxide and 75% cupric oxide.
Q:copper sulphate help?
hydrated copper sulphate when dehydrated loses the water of crsytallization. hence contracts . previously it was in solution. now in abscence of water CuSo4 molecules form crystals due to loss of heat ; as water absorbed some amount of heat in evaporation contract and form crystals..
Q:If 150mL of .055M copper(II) chloride solution reacts...HELP!?
So first, since you have the volume and molarity for the copper chloride solute, you find the moles for copper chloride. I will be using n to symbolize moles. Remember that the equation for Molarity is Molarity=number of moles of solute divided by the Volume of solution. So your first step would be solving for moles of the copper chloride. That would look like the following: .055M= n/150mL of copper chloride By multiplying 150mL times .055M, you would get 8.25moles. Next, you plug the moles into the Molarity equation again, except now you are solving for the volume of silver nitrate. That would look like the following: .100M=8.25moles divided by the Volume of silver nitrate You solve for volume by dividing 8.25 by .100M to get 82.5. This means that it takes 82.5 mL of silver nitrate to react with the copper chloride. Hope this helps!
Q:Is there Any enviromental issues associated with Copper?
copper is actually something that you do not want much of in water. It is a poison for plant life, a good algaecide, actually.
Q:Why did copper sink in CYCLOHEXANE, but float in water?
Surface tension with the water; you can also float a razor blade. Sure, cyclohexane is less dense than copper or water, but that's not the point!
Q:Why does copper have a distinct metallic smell? Pennies, for example.?
Coins harbour all sorts of bacteria, and are responsible for the transmission of a great deal of disease. Copper atoms cannot evaporate to any great extent. You are probably smelling the effects of people handling the coin for years!
Q:Where can you find any kind of copper?
in a penny?
