Copper-Iron Stoichiometry Lab Report 10/3/12 Abstract: The lab performed required the use of quantitative and analytical analysis along with limiting reagent analysis. The reaction of Copper (II) Sulfate‚ CuSO4‚ mass of 7.0015g with 2.0095g Fe or iron powder produced a solid precipitate of copper while the solution remained the blue color. Through this the appropriate reaction had to be determined out of the two possibilities. Through the use of a vacuum filtration system the mass of Cu was

RSAMI – GROUP II ‘Testing the competence of the Stroop test when taken by undergraduate students with pairs of words and colours that are congruous‚ incongruous and semantic.’ ABSTRACT This experiment was conducted using a semantic variation in addition to the original Stroop test to determine the difference in reaction times when applied to congruent‚ incongruent and semantic words and colours. The experiment was conducted with a sample of 20 (17 female‚ 3 male) junior freshman psychology

Structures‚ Biosynthesis and Biofunctions of Iron-sulfer proteins Yiming Chen‚ Brown University‚ May 11th‚ 2011 I. Introduction Iron-sulfur proteins are the proteins which contain iron-sulfur clusters‚ like sulfide-linked di-‚ tri-‚ and tetrairon centers with various oxidative states 1. An excess of 120 distinct types of enzymes and proteins are known to contain Fe-S clusters2. Iron-sulfur proteins are known for the role of the oxidation-reduction reactions of mitochondrial electron transportation

Mohammed Asif M et al studied the impact of heat input on tensile strength‚ toughness‚ micro hardness‚ micro structure and corrosion behavior of duplex stainless steel joints. Four parameters were varied by keeping speed as constant. The heating pressure of 30‚ 40‚ 50 MPa‚ heating time of 3‚ 4‚ 5 sec‚ upset pressure of 60‚ 70‚ 80 MPa‚ upset time of 2‚ 3‚ 4 sec were used to weld the joints. L9 orthogonal design concept was used. Results revealed that no intermetallic phases were formed. By increasing

Chapter 24 Industry Comes of Age The Iron Colt Becomes an Iron Horse * After Lincolns death in 1865 the railroad production went up and by the 1900s it had gone up by at least 192‚556 miles * In 1862 congress began to advance liberal money loans to 2 favored cross continent companies and gave them a lot of acres paralleling the tracks. Washington gave the railroads 155‚504‚994 acres & the western states contributed 49 million more. * Land grants to railroads were made in broad belts

The poem by William Stafford‚ “Traveling Through the Dark” presents readers with an uncomfortable and rather grim instance of the intersection of the natural world and that of man. Technology‚ in this case cars and the man-made road‚ are seen as something invasive and harmful in this poem. In order to convey the meaning of the poem “Traveling Through the Dark” by William Stafford uses a conversational style to communicate the theme in the poem of the role of technology in modern life and‚ more importantly
