In order to find the formula of the copper chloride hydrate‚ we had to separate the compound to find the mass of water and copper. To begin this process‚ we evaporated the water and created an anhydrous compound‚ meaning we were left with only CuxCly. By calculating the weight of both the anhydrous and the hydrated compounds‚ we could conclude that the difference in the weights was the weight of the H2O. From this we were able to calculate the percent composition of CuxCly and H2O (see Calculations:

Copper vs. fiber Everyone building a network must face this question at some point: fiber or copper wiring? For a usual home network or even a big office either one will suffice but what is the best option for you or your company. You have to take cost‚ distance of cabling‚ and bandwidth and speed into consideration when making this choice. Copper: a traditional copper wiring for a network certainly seems much cheaper on the surface. Copper wiring itself is dirt cheap at least comparatively

Wilson’s causes the body to retain copper that has been taken in through an individual’s diet‚ rather than the liver turning it into to bile to be disposed of. The liver becomes more and more damaged as the copper accumulates‚ and when it has no other place to be stored within the liver‚ it gets released into the bloodstream‚ carrying the copper throughout the body‚ onto other organs. This is how the accumulation of copper not only affects the liver‚ but manages to affect the nervous system‚ eyes
