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. Part Two (Spectroscopy): Create and complete a data table for Part Two of the lab. It should include the name of the element‚ the colors‚ and the wavelength values of the observed lines. Describe the line spectrum of the star. Give the color and wavelength value of

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-

caused by visible rays; this motivated him to study and earn numerous degrees from Harvard‚ MIT and the University of Chicago. He then became a full-time professor of optical physics at Johns Hopkins University He wrote many articles on spectroscopy‚ phosphorescence and diffraction. He is best known for his work in ultra-violet light. Wood has been described as the "father of both infrared and ultraviolet photography" because of the discovery of electromagnetic radiation beyond the visible

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

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
