permanganate solution to analyze an unknown iron solution by using redox titration. Theory Reduction-oxidation titration is an analytical method based on electrons transferring between an oxidizing agent and a reducing agent in solutions. Chemical analysis can be built on Redox titration if four criteria are met: a) The reaction is completed in a thermodynamically spontaneous condition. b) The reaction is fast enough to give an operational result instantly. c) The reaction does not have any side reaction

DRAFT FORMAL WRITING II Paternalism is the prevention of a persons right to choose what is best for themselves and an outside actor makes the decision based on what they believe is right. The importance of paternalism presents itself in many different areas. According to the book of bioethics‚ “The limits of our obligation to respect autonomous choices become important in the discussion of paternalism in medicine and social policy.” (Bioethics p.271)** The famous nineteenth century philosopher

rate of 300nL/min. An Orbitrap Fusion mass spectrometer (Thermo Fisher Scientific‚ San Jose‚ CA) operated in positive ion mode was employed for sample analysis. The capillary temperature and the spray voltage were set as 200 °C and 2.5kV. The data was acquired in a data-dependent mode; the 15 strongest MS1 peaks were selected for subsequent MS2 analysis. For every selected peak‚ higher-energy collisional dissociation (HCD) was performed. The MS1 spectra (350-1650 m/z) and the MS2 spectra were both acquired

Introduction: Bacteria are microscopic‚ single-celled organisms. Their genetic information is encoded in one large chromosome. It can also be found in plasmids which are small circular pieces of DNA that contain important genetic information for the growth of bacteria. In nature‚ this information is often a gene that encodes a protein that will make the bacteria resistant to an antibiotic. The reason for this protein being made within the bacteria is because of how bacteria usually grow in the same

IntroductionA dehydration reaction of an alcohol results in an alkene. This type of reaction requires an alcohol‚ an acid catalyst and heat. Generally strong concentrated acids‚ like sulfuric acid and phosphoric acid‚ are used as the acid catalyst.The acid catalyst protonates the alcohol‚ to make a much better leaving group. Weakest bases make the best leaving groups‚ so once the alcohol is protonated the leaving group leaves and produces in a carbocation and water. In order to form the double bond

Purpose: Cells produce toxic wastes‚ in this experiment hydrogen peroxide‚ and without some sort of molecule to break it down the cell will die‚ along with the organism itself. However with the aid of an enzyme‚ catalase‚ hydrogen peroxide is able to be broken down into an intermediate and thereafter harmless substances water and oxygen. The goal of this lab is to measure the reaction rate of this process in different substances such as a liver‚ a vegetable‚ and breast tissue. By using variables
