Korleyfah Mouth Chem 331 Thursday 2:00pm Dr. Lijuan Li 20A Preparation of CuCl2~2DMSO 20B Preparation of RuCl2~4DMSO Abstract In order to synthesize our metal complexes, we were able to make both Copper and Ruthenium metals. From this, we combined each metal complex with DMSO by refluxing the compound. The metal complexes were analyzed through their melting point and IR spectroscopy to determine whether the metal bonded to a Sulfur atom or an Oxygen atom of the DMSO. After analyzing the IR spectrum

Chemical Formulas Review: Nomenclature and Formula Writing Naming Simple Compounds There are four naming systems you should familiarize yourself with to succeed on the SAT II Chemistry exam. The trick is recognizing which naming system to use. Here are the guidelines: * If the compound starts with H, it is an acid. Use the naming acids rules. * If the compound starts with C and contains quite a few H’s and perhaps some O’s, it is organic. Use the naming organic compounds rules. *

Michelle Kim 2012.1.20 Biology Iso-osmolar Concentration of Carrot Cells Lab INTRODUCTION For a more thorough understanding of this lab introduction, the concepts of, iso osmolar, membrane, equilibrium, and concentration gradient evaluated. Iso osmolar can be known as the point in which the substance of experimentation faces no change despite the amount of solute inside the solvent( because the solvent and solute concentration is equal. This is where the line on a graph would cross on the

MOLE RATIO SCIENTIFIC OBJECTIVE: The main point of the experiment was to form a balanced chemical equation, the find the mole ratio. If a cloud of crystals had formed then when the two substances known as lead(II) nitrate and potassium dichromate were mixed at different doses measured in drops. with all of this being done it was about to show the mole ratio. The mole ratio the ratio of moles of what you've been given in a reaction to what you want to find. INTRODUCTION: A mole ratio is the

One of the most explicit illustrations of poly-pharmacology in dietary phyto-nutrient is Curcumin. One can consider curcumin as an ideal candidate for preventive therapeutic action in cancer as a sole agent or in combination with traditional therapies, because of its ability to target multiple number of signaling pathways relevant to cancer [168,169]. One of the approaches for identification of polypharmacological chemical compounds is “virtual screening of all potential molecular targets of interest

The book Napoleon’s buttons was an informative story that mixed slow and confusing chemistry with history. This mix allowed a history buff like me to get involved with the chemical make up and structure of common elements. Penny Le Couteur and Jay Burreson used this book to explain their theories on how key historical events are related to the chemical make up of important elements. In essay after essay they explain the history and events. In addition, they go further in depth to explain the details

The History of Chemistry is ancient, starting at 1000 B.C to present time. Chemistry has evolved drastically over the centuries. the first civilization to take over chemistry were the Egyptians and Babylonians founded practical knowledge concerning the arts of metallurgy, pottery and dyes, but didn't develop a systematic theory. In this period of time tons of civilizations tried to figure out the life of chemistry and how it worked. A basic chemical hypothesis first emerged in Classical Greece

History of chemistry encompasses a span of time reaching from ancient history to the present. By 1000 BC, ancient civilizations used technologies that would eventually form the basis of the various branches of chemistry. Examples include extracting metals from ores, making pottery and glazes, fermenting beer and wine, extracting chemicals from plants for medicine and perfume, rendering fat into soap, making glass, and making alloys like bronze. The protoscience of chemistry, alchemy, was unsuccessful

The Effect of Temperature on the Rate of Reaction Aim-We is going to investigate how temperature effects the rate of reaction when we use a Magnesium Ribbon and dissolve it in Hydrochloric Acid. Different Variables-There are four different variables that effect the rate of reaction, surface area, concentration, temperature and catalysts. Here is some information on each variable with diagrams. How does surface area effect rate of reaction? In a substance
