When chloroplasts were suspended in an aqueous extract made from an acetone-leaf preparation‚ oxygen in measurable amounts was evolved in light.( ) This rate can also be inhibited with herbicides such as Artizine. Atrizine is one of a group of

chemical compounds that uses a chemical reaction in the device to produce a color change and give an estimate of BAC. With modern technology being introduced in practically anything today‚ this can contribute to the accuracy of alcohol breath tests. Acetone‚ which painters can be exposed to‚ is at risk of interfering alcohol breath tests. However‚ with Electrochemical Fuel Cell technology in a Breathalyzer‚ it can not interfere with the test results because of how highly specific and sensitive it is

Experiment 2: Intermolecular Forces Performed: 9/12/2011 Submitted: 9/20/2011 Chemistry 1046L PART I: Purpose: The purpose of partI in this experiment is to identify a variety of unknown substances’ properties using observations of the temperature changes that occur during evaporation. We know that substances with weaker intermolecular forces‚ such as London dispersion‚ will have a faster vaporization rate and thus a higher temperature difference compared to

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
