Q:using copper electrodes: Copper (II) tetraoxosulfatate (VI) Give us a break. How about copper (II) sulfate? CuSO4. Applying a voltage to the copper electrodes of this solution will produce hydrogen gas at the electrode connected to the negative pole of the battery, and oxygen gas at the electrode connected to the positive pole of the battery. The copper sulfate will function as the electrolyte and the hydrogen in water will be reduced (gain of electrons) and oxygen in water will be oxidized (loss of electrons). OILRIG = Oxidation Is Loss, Reduction Is Gain.

Q:I need these rings for a project in my medals class. I have tried many stores. I tried Walmart, because they said they had them online, but they really DIDN'T. I also tried Joanna's and Michel's craft stores but they don't know if they are real copper or not. I also even tried home dept., but nothing there.: Medals class or metals class? Copper is a poor metal for jump rings as they are usually supposed to be firm and springy and copper in soft on most of its alloy forms. I tried Walmart, because they said they had them online, but they really DIDN'T. Does this mean that you ordered it online and what you got wasn't copper or you wandered into the Walmart and expected to find it? Because a huge percentage of what Walmart offers online is NOT available in the stores because they are very aggressive in having in the stores what sells rapidly. Worse, the craft selection in most Walmart's is extremely limited. You may have to search out suitable wire and make them yourself.

Q:Who knows GREE air conditioning, two pieces of smallpox confidential, match what big copper tube?: 9.52 /15.88 has many models, or it may be 6.35/12.7. answered

Q:What is the main cause of the sticking of the inner wall of the condenser copper tube? How to deal with it?: This advertisement place is comprehensive preferential investment! Welcome to advertise! Answer: there are two kinds of attachments in the condenser copper pipe, one is organic attachment, and two is inorganic attachment. Organic produce attachment is due to cooling water containing algae and bacteria, they often clings to the walls of the tube in the clean copper pipe, and at the appropriate temperature (10oC-30oC), absorbing nutrients from the cooling water, the continuous growth and reproduction. Organic attachment often and some clay, animal and plant debris, as well as some peat particles mixed together.

Q:Also which element has the greater tendency to retain electrons, copper or hydrogen?: Definitely Hydrogen. The radii of copper is longer than Hydrogen and that leads to a higher shielding effect. Shielding effect means inner electrons are block and therefore copper atoms can easily lose electrons to become octet. Besides, Hydrogen atoms have a high ionization energy (1312.0 KJ/mole). Ionization energy refers a force needed to lose an electrons. The higher ionization energy, the harder to lose electrons. I hope it helps and I am glad! Because I am not an expert in this field!!=]

Q:Is Haier refrigerator made of copper tube?: The refrigerator in some places is copper in some places is aluminum, which is based on the use of the environment according to the refrigerator in the pipeline with fins for heat dissipation, if the use of copper will be because of surface oxidation and good heat dissipation on the pipe wall frosting defrosting is formed after the customs clearance, produce Tongxiu have influence on the pipeline, pipe more needless to say. The copper tube is suitable for use in the environment which is long in the low temperature environment and does not touch things directly or indirectly

Q:would that work?many thanks: Definition of redundant is needed. The vessel was most likely designed with the I/B in the plans, that means X weight to sit in the water at X depth. Usually yes, just make sure and do it on the hard and put something in that area that can be utilized and has the same or near weight of that Out-drive. A generator would be my first option. If she has an inboard then she has the out stacks or flows to ventilate and exhaust properly, use that to your advantage. I am guessing that you have an Out Board that hangs off the transom or is in a well, hence redundant. A plate can be used to secure the through hull, that is what I would do if it were my vessel. You would maybe use a sea-cock, that would leave the option of re-powering and also leave it OEM. Most every mono-hull sailboat is a Displacement Vessel. A sea-cock is the ideal remedy for that, but pay attention to the displacement, load shifts can cause very extensive and often unrepairable damage to a hull. Standing water can also, so sea-cock it properly, dry it as needed and enjoy it as much as you are able to. Always wear a PFD.

Q:Here is my question:How many grams of copper should be produced when 2.00g of copper (II) chloride dihydrate reacts with excess aluminum according the following equation?3CuCl2 o 2H2O + 2Al --&gt; 3Cu +2AlCl3 +6H2OMy answer was 0.878g. Is this correct?: 2.00 g * mol / 170.48 g * 3 mol / 3 mol * 63.55 g / mol = dyhydrus CuCl2 has atomic mass of 170.48 copper hass atomic mass of 63.55 2 * 63.55 / 170.48 = .746 g Cu made

Q:Pin holes developing in copper water pipes.: usually that is caused by whatever is outside the pipe, not the water in the pipe in some areas alkaline soil does a number on copper pipes and makes them leak
