the Berkeley Pit is of the most serious environmental problem. A former open pit copper mine, Berkeley Pit, is now one of the most closely observed disaster in our nature today. The cause of the development of the chemical disaster traces back to the 1950s. As the Industrial Revolution took place, mining took a significant role in city life. According to the Berkeley Pit Public Education Committee, “in 1955, copper prices

of basic copper carbonate 〖mCuCO〗_3⋅n〖Cu(OH)〗_2 were observed by changing the reaction mole ratio. The reaction mole ratio of sodium carbonate to copper chloride (II) was controlled from 1.08 to 1.68. Fig. 1 shows the XRD patterns of copper carbonate powder. At a reaction ratio of 1.08, paratacamite (Cu_2 Cl(OH)_3 ), beside alkali copper carbonate, was formed because of incomplete reaction at a copper content of 53.9 wt%. Lack of sodium carbonate may cause incomplete reaction with copper chloride

a low percent yield is that the starting materials did not completely react with each other meaning that the reaction did not produce the full amount of product possible, which could be avoided by allowing the reflux to continue for more time. For copper tetraphenylporphyrin the theoretical yield was 0.023g and the actual was 0.0274g, making the percent yield 118%. Possible explanation for a large percent yield could have been due to the product not being completely dry when being weighed or the presents

For some people, the topic of family is very controversial. While some family dynamics might seem like ones who are placed on an advertisement for a Loews magazine, most families have underlying problems that take place behind the scenes. It is undeniable that putting two works into conversation with each other can have several advantages. For example, in the poems “My Papa’s Waltz” by Theodore Roethke, and Lucille Clifton’s “forgiving my father” they both portray their childhood memories that aren

Children are often expected to forgive their parents for any mistake their parents may have made, however forgiving and forgetting are not the same thing. How parents nurture their children has a significant role in those children’s lives. Children may have forgiven, but forgetting is a not always as easy or even possible. Theodore Roethke’s poem “My papa’s waltz” and Lucille Clifton’s “forgiving my father” recalls the speakers’ respective childhoods and treatment by their father. The poem shows

Chemistry Aim: I am trying to find out whether the equation 2CuCO3 ® Cu2O + 2CO2 + ½O2 or the equation CuCO3 ® CuO + CO2 is correct for the decomposition of copper carbonate. Introduction: This is my background research, this information may help me when I am trying to see which equation is correct. I have used the book Chemistry 1 by OCR as my reference. Relative Atomic Mass: This is the mass of an atom of the element

The morphology of pristine CuO nanoparticles are determined by TEM micrograph as shown in figure 3 (a), the exhibits stacking of small flakes broken of CuO nanostructures giving leafy profile which had agglomeration. The leaf-like flakes have small width with an average size of the flakes is 500–600nm and thickness ~20–30nm. The corresponding SAED pattern (Fig. 3b) clearly shows that the CuO flakes are polycrystalline. Similar observation has obtained by SEM results (Fig. 3c), which demonstrates

Copper mining became extremely popular in 1843 in what is now known as the Copper County. Here was on the only place in the whole United States of America to get pure, native copper, that was until the early 1900s. The first documented reports of copper being found in Michigan was in 1667 by Claude Allouez, a missionary from France. In Allouez's report, the Native Americans in the Lake Superior area, known as the Chippewa's, really valued the copper nuggets they found there. The Upper Peninsula was

Head office of this organisation is in Melbourne, Australia.  BHP BILLITON also provided steel for Sydney Harbour Bridge. BHP BILLITON is also a part of the first Military Aircraft in Australia. (Edumine, 2015)  BHP BILLITON stayed on top in progress of gas and oil. It emerged highest scores in 2014 and 2015. (Disclosing annual report, 2015)  In 2005 BHP BILLITON became second largest copper producer and third largest nickel

compounds (sulphates) were combined, they will react according to the Activity Series of metals. In our experiment we hypothesized that when magnesium metal and copper sulphate combines, it will produce an aqueous solution of magnesium sulphate and copper metal. When zinc metal and iron sulphate are combined, an aqueous solution of zinc sulphate and iron metal is produced. When iron and tin chloride are combined, iron chloride and tin are formed. When tin is combined with copper sulphate, an aqueous
