The Copper Cycle Alexes Montalvo Chem 1500-10 September 26‚ 2012 The Copper Cycle Introduction: The Copper Cycle is a popular experiment used to determine if an element‚ in this instance‚ copper‚ reverts to its elemental form after a chain of reactions. This experiment is very dangerous because of the reactions between the strong acids and bases. In this experiment I performed a series of reactions starting with

Introduction Curled Metal Inc (CMI) is a company whose strategy evolves selling products that used certain types of metal as a raw material. CMI rapidly grow in the last decade due to Slip-Seal‚ a product that meet the demanding specification of the automaker imposed by US strict environment legislation. In order to diversify offer from auto industry‚ CMI’s management decided to examine a new application for curled metal technology. Situation Analysis Company Business Model and Competitive

Synthesis and Characterization of Zn(TPP) and Cu(TPP) Complexes 1 Project Summary The overall goal of the project is to synthesize two metalloporhyrins‚ (Tetraphenylporphyrinato)zinc(II) and (Tetraphenylporphyrinato)copper(II). Because metalloporphyrins occur naturally in hemoglobin and chlorophyll‚ their study has implications in synthesizing human blood as well as utilizing its ability to convert visible light to energy. In addition to these two applications‚ metalloporhyrins are utilized in

Copper and Molybdenum Deposits in the United States Copper and molybdenum resources were not recognized as valuable commodities until economic needs demanded the collection and processing of these minerals in large amounts. The most expansive deposits of copper and molybdenum occur in massive low grade ores and are found in intrusive porphyry formations‚ although many smaller sized but higher grade ores are located in non-porphyry areas. The nation has abundant domestic copper ore reserves but

Transition Metals 1a) The d-orbitals of a free transition metal atom or ion are degenerate (all have the same energy.) However‚ when transition metals form coordination complexes‚ the d-orbitals of the metal interact with the electron cloud of the ligands in such a manner that the d-orbitals become non-degenerate (not all having the same energy.) The way in which the orbitals are split into different energy levels is dependent on the geometry of the complex. Crystal field theory can be used to predict

Purpose: In this lab‚ we will heat up a metal rod and measure how much it expands. We will calculate its Coefficient of Linear Expansion‚ α‚ and prove the formula for thermal expansion‚ ΔL = αLiΔT. Also‚ we heat up a known volume of methyl alcohol and calculate its Coefficient of Volume Expansion‚ β‚ and prove the formula for volume expansion of a liquid ΔV = βViΔT. Equipment: Hollow Metal Rods of different metals‚ Steam Generator‚ Stand‚ Burner‚ Flexible Hoses‚ Motion Amplifier‚ Micrometer

Rocks containing copper compounds (such as copper carbonate) are called ‘copper ore’. Copper is extracted from copper ore by a series of chemical‚ physical‚ and electrochemical processes. Ores can be classed as ‘high grade’ or ‘low grade’ depending on the percentage of copper compounds (e.g. copper carbonate) they contain. After mining‚ the ore is crushed‚ roasted‚ smelted and then electrolysed to extract the copper. Suggested Equipment Boiling tube Samples of different carbonate ores‚ containing
