Copper vs Fiber Some advantages of Copper Cabling are Power over Ethernet this gives you the ability to power phones‚ surveillance cameras‚ Wireless Access Points‚ and many other devices right through the networking cable itself. That means that you don’t have to schedule an electrician in to run power to your surveillance cameras to power them. Another advantage is the ability to have an emergency power supply that will continue powering mission critical devices even if your electricity goes

The Ok Tedi Copper Mine Ethical Issue * Opening the mine without a waste storage. If they would have waited to open the mine for the waste storage to be completely finished they never would have started disposing trailing in the river. * Environmental damage along the Ok Tedi. The environment that is affected is the river‚ the fish‚ the forest area along the river‚ the gardens‚ and hunting resources. The damage is already done to the environment. How long will it take to get

When you mix copper‚ silver‚ and nitrate together‚ you will end up with silver nitrate solution will turn blue (it has become copper nitrate). On the piece of copper‚ there would be a coating of solid silver. If a chemical reaction is going to be observed when chemicals are mixed‚ heated or any other means of altering the substance‚ then we will be able to predict the products formed. If it is observed that in the original versus the changed substance no new substances are formed‚ the change is reversible

Determining the Percentage of Copper in a Copper Ore Aim: To determine the percentage of copper present in malachite. Hypothesis: That the percentage of copper in the malachite will be four percent. Materials: 2 x 250mL beaker‚ pestle‚ malachite‚ sulfuric acid‚ water‚ 2 x filter paper‚ funnel‚ filter stand‚ Safety Precautions: Wear safety glasses at all times when dealing with chemicals and apron to avoid ruining clothes. Method: Record the mass of the malachite sample. Place the malachite

magnesium ribbon was placed in covered crucible and was heated in order for it to react with Oxygen presented in air and in water provided. The result showed that Magnesium oxide formed through chemical reaction was made up of 60.19% magnesium and 39.81% oxygen‚ which is approximate proportion of both particles in every Magnesium oxide compound. From this lab it can be concluded that the law of definite proportion stating that the elements in a pure compound combine in definite proportion to each other

Conclusion The purpose of this experiment was to discover the chemical properties that copper has when reacting with other chemicals and how it changes physically during these processes. (Department of Chemistry‚ 2013) This was achieved through many types of reactions‚ such as a redox reaction‚ double displacement‚ decomposition reaction and single displacement depending on the chemical properties in relation to copper of the other substances when it was added with copper. Copper was either in an

examine the extent to which the temperature and presence of common ions affect the amount of copper sulphate salt that can dissolve in 100 grams of water until it reaches saturation. In order to achieve the aims of this experiment‚ a methodical approach is taken to measure solubility of the salt at three different temperatures and then construct a solubility curve for copper sulphate. Additionally‚ copper sulphate is reacted with sodium hydroxide to investigate further the effect of common ions on

throughout the experiment. (1) Weigh three clean dry labeled 125 mL erlenmyer flasks on an analytical balance. Place about 0.135 grams of oxalic acid dihydrate‚ H2C204.2H20‚ into each of the three separate flasks and reweigh the flasks containing the acid. (2) Set up a buret with KMnO4 solution to be standardized by titration. (3) Dissolve each acid sample in about 25 mL of distilled water. Again don’t mix up the samples. Take one flask and add 1-2 mL of concentrated sulfuric acid
