to transmit the signals from the airway adapter to the monitor for the purpose of displaying the EtCO2 values. • Sensor- The purpose of the sensor is used to collect a sample of gas from the patient’s airway and using infrared spectroscopy or mass correlation spectroscopy method to determine the value of EtCO2. Depending on the type of operation‚ the sensor is either placed on the adapter itself or is located at a distance from the adapter.

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‚ it was determined that S=O shifted to a lower wavenumber in CuCl2~2DMSO and that S=O shifted to a higher wavenumber in RuCl2~4DMSO

product from the cyclohexanol starting component‚ previously learned lab techniques such as extractions and simple distillation were used. The formation of the product was verified by performing a Bromine test as well as an analysis using IR Spectroscopy. A percent yield of 8.33% was obtained. Introduction: In an elimination reaction‚ two substituents are removed from a molecule in either a one or two-step mechanism. There is a removal of a leaving group and a proton to form alkenes. The

Our data displayed supports the notion that by increasing the acidity of the catalyst‚ the production of aspirin will increase. Our hypothesis was proven correct. In our data‚ we calculated the percent yield and percent error of each trial. We also calculated the average of the percent yields and the percent errors of each catalyst. In the end‚ we saw that for the sulphuric acid catalyzed aspirin‚ we saw an average of 69.7% percent yield and an average 30.3% percent error. As for the phosphoric acid

Vietnam War Research Paper: During the 30 years of XX century Vietnam was at war. It all started in the 1940′s‚ when the Communists fought against French colonial rule‚ and was completed in 1975 with the fall of Saigon. The period‚ which the Vietnamese know as the “American War” and the Americans call the “Vietnam War”‚ lasted from 1965 to 1973‚ during the time of the U.S. intervention. The communist leader Ho Chi Minh led his forces based in the north and defeated the French in 1954

separate a mixture containing a carboxylic acid and a neutral compound. Once recovered‚ the solids were purified by recrystallization and examined by thin-layer chromatography‚ and their identities were derived by melting point and infrared (IR) spectroscopy. Extraction is a procedure that selectively dissolves one or more of the mixture compounds into a proper solvent. Extraction refers to the moving of compounds from one liquid solvent to another liquid solvent. A compound can be disconnected
