The prescribed procedure produced nylon. The initial indication that nylon was being formed was through the combination of 0.02M of sebacoyl chloride in hexane and 0.05 M 1‚6 hexanediamine. Due to the fact there was an evident product formed after the combination of these two solutions‚ this simply shows that nylon was produced. The prescribed procedure produced nylon due to the fact that there was a present product of the reaction within the IR spectrum. The main peaks of frequency for the unknown

CHAPTER 1 Introduction and Its Background Introduction Infectious diseases are one of the main contributors to global mortality and morbidity. Infectious diseases are caused by pathogenic microorganisms‚ such as bacteria‚ viruses‚ parasites or fungi. These diseases can be spread‚ directly or indirectly‚ from one person to another. Vaccines‚ antibiotics‚ and many other advances have lessened the impact of infectious diseases. Unfortunately‚ this has not been true everywhere. It has not been true in

briefly explain why you identified each unknown as you did. 3 Unknown 1 was sodium and unknown 2 was potassium. Each element has it’s own color so all I did was match the element’s colors I had already tested with the unknown’s color.

it was because she got yellow and each element corresponded a unique color. The second element potassium knew it was because I acquired a blue color‚ in the experiment verified that each element corresponded to a different color.

were found. Consequently‚ this discovery had raised theories that these tattoos may have been a likely “ancient healing practice” that may be related to acupuncture. Maria Anna Pabst of the Medical University of Graz in Austria used microscopy and spectroscopy to examine the tattoos. Since the tattooed neck circles contained a plant material instead of ash or soot‚ Pabst suggests that these tattoos were most likely part of a healing or strengthening practice. The tattooed circles are near what is known

Title: Studying SN1 and SN2 Reactions: Nucleophilic Substitutions at the saturated carbon Lab Partner: Jeszie Geronimo Objective and purpose: the purpose of this experiment is to convert a primary alcohol to an alkyl bromide using a Sn2 Reaction. Investigate some factors that influence the rate of Sn1 reactions. The second part of this lab will focus more on how unlike factors influence the rate of reactions in anSN1 reactions. The factors that we will be inspecting are the leaving groups‚ Cl-

Application of Normal mode calculations in optical spectroscopy | Phym 221 – Assignment 4 1. Introduction Normal modes are used to describe the different vibration motion in molecules. There are different types of modes for molecules in different motions and each has a certain symmetry associated with it. 2. Overview of Normal Modes Generally‚ normal modes are independent atoms in a molecule that are in motion such that they do not disturb the motion of the other molecules. Normal modes

A Brief Summary on Robert J. LeRoy and the LeRoy Radius Theory As a graduate with a focus on computational chemical physics at the University of Toronto‚ Dr. Robert J. LeRoy began a career in the department in the theoretical chemical physics at the University of Waterloo. His commitment to a career to the science world is sparked by the research that goes along with it. He demonstrates his belief that in all basic or applied human endeavors one should be as challenged as they are rewarded‚ ”Finding

unnecessary pain and suffering to the animals and doesn’t often ensure similar impacts in humans‚ is unnecessarily rehashed once the experimental results have been verified.The “Kinetics of Ethanol Oxidation” laboratory experiment utilized Beer’s law and spectroscopy to monitor concentration and the rate of ethanol oxidation through the LoggerPro System. This data then helped determine the kinetic rate constant‚ k‚ and the order of the reaction. First‚ the wavelength of maximum absorbance was determined using
