School of Chemistry @ Pietermaritzburg University of KwaZulu Natal Chemistry 310 Substitution reaction of Molybdenum Hexacarbonyl: the use of infrared spectroscopy as a structural tool in metal carbonyl chemistry. Abstract The synthesis of isomer A and B of [Mo(CO)4(PPh3)2] were prepared from molybdenum hexacarbonyl‚ sodium borohydride and triphenylphosphine with a % yield of 79% and 8.5% respectively. Two isomer was identified using IR spectra and from isomer A four C≡O stretching

Investigating the Kinetics of the reaction between Iodide ions and Peroxodisulphate (VI) ions By the use of an Iodine clock reaction I hope to obtain the length of time taken for Iodine ions (in potassium iodide) to react fully with Peroxodisulphate ions (in potassium Peroxodisulphate). I will do three sets of experiments changing first the concentration of iodide ions‚ then the concentration of Peroxodisulphate ions and finally the temperature of the solution in which the reaction is taking place. From these

1220 words Hypersensitivity and Panic: Race Issues Behind South Park Since the government issued some policies to make racial discrimination illegal and Since President Barack Obama succeeded in stepping on the American political stage‚ it seems America has entered the post-racial era. However‚ even though the U.S. has made an improvement in terms of racial issues‚ it is not easy to completely change the whole nation’s attitudes towards minorities. In fact‚ stereotypes and panics about minorities

Isolated DNA Products Amplified Via Polymerase Chain Reaction and Cloned Biotechnology: DNA WPUNJ December‚ 2012 Abstract Isolated DNA from mouse‚ plants‚ and plasmid DNA were used for Polymerase Chain Reaction (PCR) for DNA amplification. The purpose of this experiment was to study the success rate or optimization of PCR of DNA‚ using both manual and kit methods. This set of experiments gives an insight to the relative difficulties associated with the optimization of a variety

Enzymes are proteins which serve to reduce the activation energy required for biological reactions (Russell and others 2010). This allows biologically important chemical reactions to occur rapidly enough to allow cells to carry out their life processes (Russell and others 2010). Enzymes are made of one or more polypeptide strands‚ which individually or as an associated complex take on a three-dimensional shape. When properly associated‚ these shapes form the active site and other supporting structures

confronted with aggression one can fight or retreat. In what ways are reactions to aggression presented in the work you have studied? Emotions are easier shown than written. Every action has its equal and opposite reaction‚ and to portray this‚ a great deal of detailed observation and a sack full of eloquent choice of words are required from authors. In the book‚ Wide Sargasso Sea‚ Jean Rhys portrays the different reactions to aggression through the abundant use of diction‚ innuendos‚ and sensory

Reaction on Reaction Paper The first thing that came to my mind when I have heard about Reaction paper is “What exactly is it?” and before I get an understanding of that‚ I resisted that change. But later‚ when I have studied about it and understood its purpose‚ I have started thinking “Why people avoid change at the first look without an analysis?” The general human tendency is to live in a comfortable zone in which he has lived for quite some time. He draws a circle‚ thinks that circle is his

was suppose to be. The reaction was incomplete and had to be stopped because of time‚ which explains the very high percent yield of the water and the very low percent yield of oxygen. The yield of the catalyst though‚ came out to a perfect ‚ which means that including uncertainty‚ there was as much MnO2 that came out of the reaction as was put in the reaction. This proves that catalysts do not get consumed in the reaction‚ with added evidence that even though the reaction was incomplete‚ the catalyst
