Identification of a Copper Compound by Percent Mass Unknown Compound: #9 Abstract: The objective of this experiment was to identify the unknown pure copper salt compound of #9. To do this‚ the mass of copper in the unknown was calculated and then divided by the mass of the whole compound to get the percent copper. The molecular weight was also calculated by dividing mass of copper compound used by moles of compound in unknown sample. The percent copper averaged out to 31.6% while the molecular

It has been used as a speaker system wire‚ telephone wire‚ computer cable wire etc. for over years now. Optical fiber comprises of plastic or glass strands to transmit data or information digitally with the use of light rather than electricity. On the other hand‚ copper cable encompasses of a single thread of copper. The size of the cable

Copper Mining in Zambia Norman Mulimbwa Shachile WHUT‚ Luoshi Rd.‚ International students building No.8‚ Wuhan‚ 430070‚ PR China Abstract The mining industry has been the economic and social backbone in Zambia since the first major phase of exploitation of the Copperbelt ’s Cu-CO deposits commenced in the early 1930 ’s. Since that time a wide spectrum of other metalliferous and non-metalliferous resources have been discovered in Zambia and although exploitation of these has been limited‚ they

KENNECOTT COPPER CORPORATION CASE REPORT 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? Prior to the consideration of Carborundum as an acquisition target‚ Kennecott‚ a copper company‚ pursued an acquisition of Peabody‚ a coal company‚ for $285 million in cash in 1968. There are two main rationales behind the acquisition of

1. (45 points) Calculate the value of Carborundum (on an aggregate and per share basis) using both the Free Cash Flow to Capital (FCFcap) and Free Cash Flow to Equity (FCFeq) methods. Use the following assumptions: Note: Rf=5.6%; MRP=8.8%‚ Carborundum’s levered beta (prior to deal)=1.16 FCFeq=Net Income + Non Cash Deductions-Capital Expenditures-Change in Net Working Capital-Debt Repayment+ Debt Issuances + Miscellaneous Extras Answer: Value of Kennecott using FCFcap is: $53.8 Value of Kennecott

Problem Does temperature affect the resistivity of different sized copper wires? Hypothesis I think that the resistivity will increase with higher temperatures because with higher temperature‚ resistivity is higher due to the fact the atomic lattice structure increases. Background Electrical resistivity is the measurement of how a material opposes the flow of an electrical current. On the other hand‚ electrical conductivity () is the inverse of resistivity. It is the measurement
