North American Electro-Deposited Copper Foil

Before placing the Aluminum foil into the Copper Chloride Water (CuCl2 + H2O), I had examined the characteristics of the aluminum foil. It came to view that the Aluminum foil was a silver-coloured, shiny metal. When the aluminum foil was placed into the CuCl2 Water solution, several observations were made.

The purpose of the experiment is to cycle solid copper through a series of five reactions. At different stages of the cycle, copper was present in different forms. First reaction involves reaction between the copper and nitric acid, and copper changed from elemental state to an aqueous. The second reaction converted the aqueous Cu2+ into the solid copper (2) hydroxide. In the third reaction Cu(OH)2 decomposed into copper 2 oxide and water when heated. When solid CuO reacted with sulfuric acid, the copper returned to solution as an ion (Cu2+). The cycle of reactions was completed with the reaction where elemental copper was regenerated by Zn and Cu

Well, there are a few bad things about copper but there are much more positive effects than negative. An example of a negative effect would be the rain water reacting with the side products of a mine. Also the mining harms the environment in a few ways. The fact that we discovered copper lead made mining more valuable which leads to the fact that Copper is a small reason that humans mined so much. Also copper is used in military equipment such as bombers, or nuclear submarines. This equipment can be seen as either good or bad but since its only purpose is to kill people or win a conflict I am against

Throughout history, women have been expected to fit into a rigid gender stereotype. Women in the early 1900s would be expected to care for children, be able to do household duties and obey everything their husbands instructed. Those women that did not fit the stereotype were looked down upon by members of society and were often alienated. Edna, the protagonist of the novel, had to battle her inner conflict of not wanting to conform to society's standards throughout the novel. Over, and over again, she was reminded of the fact that she was different and that society did not approve of her way of thinking. In the novel The Awakening, by Kate Chopin, the author uses the characters and their actions in society to express the oppression and expectations society had towards women.

The Cu Later lab experiment is designed to allow you to practice lab skills in implementing and performing a series of reactions. Specifically, four types of chemical reactions will occur: oxidation/reduction; double replacement; single replacement; and decomposition. You will begin with a known amount of copper metal, which, after progressing through several steps, is reproduced. In this experiment you will observe and record the various changes such as heat, color changes, and production that occur. This procedure is used to observe some chemical reactions of copper and its compounds while also performing the lab appropriately as to retain the copper as much as

The Copper Basin of southeastern Tennessee is an area that is climatically unique with a rich history rooted in copper mining. It is thought that man is responsible for the total destruction of the environment over this large area, but it is mostly contributed to the exclusive location. The Copper Basin was susceptible to negative environmental effects due to its topographical, geological, climatic, edaphic, and meteorological location. However, the copper mining had a transformative effect on the surrounding lands that of which are still recovering.

Designed by Lee Schmidt and Brian Curley, this 18-hole championship golf course proves the perfect course for any player. Maintained to the highest of standards, the wide fairways and wavy greens prove to be easily playable, and have become a trademark at Copper Canyon. If this doesn't encourage you to play here, perhaps you will be indulged by the surrounding landscapes that prove to make Copper Canyon a truly special course. You will also find that the surrounding landscapes is not all that this golf course offers in regards to its beauty, as over 11 beautiful lakes are featured on the course itself, making an all round mesmerizing golf course.

13) When the tray is thoroughly dry, determine its mass. Record the mass in the data table. You have to wait until day three to weigh the copper.

Before the synthesis of the Copper Iodine Compound, the identities provided (CuNO3)2 and Nal weighed 1.65 g and 4.7 g, respectively. After being weighed, the (CuNO3)2 exhibited a blue color, while the Nal, through observation, was a white color. However, when both identities were combined, the product turned into a brown and red rocky material. Once 20 mL of deionized water was added, the product quickly turned pale pink paste. After the solution was repeatedly washed with a total of an additional 100 mL of deionized water, the product was powdery and pink with small grains, and was left to air-dry. Once the product was air dried, it was observed to be a pale pink color, while the filter paper was stiff as the product was hard and dry. Therefore, the solid was scraped off onto a recrystallizing dish. However, the mass of an empty recrystallizing dish needed to be recorded in order to compare how much of the synthesized copper iodide was obtained. Within this case, the empty recrystallizing dish used weighed 32.01 g, the product on the empty dish weighed 1.03 g, having a total weight of 33.04 g.

XIII. Carefully remove the copper metal from the filter paper onto the watch glass. (with a spatula) Place a 400 ml beaker on a hot plate contained with water. Carefully place the watch glass before the water boils to dry the copper metal. (Use the tongs to handle the hot watch glass)

Going along with an expanded life span, Galadriel also had to deal with grief for a long and probably distressingly painful amount of time. Throughout her prolonged life she dealt with whatever came her way in a stern yet passive way, rarely actually taking action from what Tolkien shows us. However, the movie adaptations do give her more of an active life. Lúthien in this regard is almost a foil to Galadriel because she was all about action. When her true love was being held captive by Sauron she sprang into action saving him from immeasurable pain and suffering. From there if Beren went somewhere she went too, never backing away from a fight. She truly was an elf maiden of action, even at one-point begging Mandos for the life of Beren, Lúthien cared more for personal relationships that gaining wisdom. It is uncertain whether Galadriel would have attempted these same actions or rather just accept her faith. Nether option is wrong or right, just different sides to the same coin.

Purpose: The purpose of this experiment was to observe the many physical and chemical properties of copper as it undergoes a series of chemical reactions. Throughout this process, one would also need to acknowledge that even though the law of conservation of matter/mass suggests that one should expect to recover the same amount of copper as one started with, inevitable sources of error alter the results and produce different outcomes. The possible sources of error that led to a gain or loss in copper are demonstrated in the calculation of percent yield (percent yield= (actual yield/theoretical yield) x 100.

This purpose of this experiment is to calculate the thickness of a sheet of aluminum foil. This experiment is necessary because the human eye cannot accurately measure the small thickness of aluminum foil with only a ruler. However, to understand the procedure one needs to understand conversion, density, and volume. Conversion is when one converts one unit to another unit using a conversion factor(e.g. 2.54cm/in). Density is how much mass there is in a certain volume(density=mass/volume) and it stays constant in a substances and mixtures that have the same composition. Volume is the amount of space that an object occupies. The experiment will consist of weighing of aluminum foil, measuring the length and width, then converting these values

1. Analyze the economic rationale of the Carborundum acquisition. Under what conditions an acquisition would be expected to add to shareholder value in general? Do any of these reasons apply to Carborundum acquisition?
