    Sociological Observation

    • 2068 Words
    • 9 Pages

    INTRODUCTION Have you ever observed the interaction of two people and based on their body language you arrived at the conclusion that they may have been divorced for a year, remarried two years later, and on the verge of another divorce? Ok, that may be a little too detailed and you have keen observation skills, but what about observing one individual? These are some of the times that we bring out our Sociological Imagination which is the ability to see our personal lives in the context of the history, culture, and social structure of the larger society within which we live (Rohall, Milkie, & Lucas, 2014). In this assignment, I will provide observations from a recent field observation based on the Social Psychology perspectives. FIELD OBSERVATION LOCATION / ENVIRONMENT It was the 19th of October, 2016 and it was a slightly overcast day. By the way, did I mention that it was about 1200PM so it was lunch time. What better place to go for lunch and to observe than at the Fort Carson Post Exchange (PX) Food court (where just about everybody on post comes to grab a bite to eat as well as “socially interact” about the way society as well as status and roles have affected their day so far). You could smell Charley’s, and Burger king as you entered the food court with a hint of Anthony’s Pizza and Taco Johns on the side. In order to perform my field observation without looking extremely conspicuous, I decide to meet with Mrs. Benjamin for lunch (and I can also talk about how…

    Objective The purpose of the experiment is to synthesize multiple cobalt complexes with various ligands and explain the ligand field transitions of these complexes using Ultraviolet-Visible (UV-Vis) spectroscopy. The experiment provides insight into specific colors of certain molecular species and respective bonding information. Introduction Transition elements are defined by the IUPAC as atoms that have an incomplete d-subshell, most commonly referring to the d-block.1 When transition metals…

    Pre-Lab Questions 1. What are the steps of the scientific method? Briefly explain each. • The steps of the scientific method are observation, define problem, construct a hypothesis, test the experiment/ gather evidence, and draw a conclusion. Observation is the procedure of collecting information about events and processes carefully. It involves with seeing and hearing. Defining the problem is when you identify a conflict that requires a solution to be solved. A hypothesis is a proposed…

    electron configurations for each of the elements. From this data you can find the total number of electrons, the total number of shells and subshells, as well as how many electrons are in each shell. The large number (the one in 1s2 ) will tell you the shell that the electrons are in. For example, helium (He) has one shell, so its electron configuration is 1s2. Furthermore, the electron configuration tells you what subshell each of the electrons occupy. The subshell is the letter next to the…

    off the edges of the beaker, and sent off tiny sparks. When the element was added to the weak acid H2SO4, a similar reaction occurred. The element reacted immediately and bubbled. A gas was let out and the element completely dissolved, leaving the acid cloudy and opaque rather than clear. When the element was added to the weak base NaOH, it also reacted immediately and completely and let out bubbles and gas. The third element (A5) tested was an unknown transition metal. The density was…

    Results and dissection 3.1 Transition metal complexes of the macrocyclic, H6L Ligand 3.1.1 The macrocyclic, H6L Ligand The physical and analytical data of the macrocyclic, H6L ligand and its transition metal complexes were shown in Table 1. From the investigation, the expected structure of H6L with its possible toutomeric forms can be represented as shown in Figure 1. H6L ligand is highly symmetric under the point group C2v symmetry and can show all the normal modes of vibrations by solving…

    combination of the hydrogenated complex, ammonium or ammonia, and a methyl radical; a radical rebound (RR) to form a methanol adduct and ammonium; methanol dissociation from the metal; and catalysis regeneration via oxygen atom transfer. We modeled these steps as stationary points throughout the reaction coordinate, each point consisting of a sum of the reactants, intermediates, or products of each step. Our research mainly focuses on the energy barrier of the C-H…

    manganese cobalt oxide (NMC) made up many of these batteries and could dissociate in aquatic environments. Prior experiments, such as Hang et. Al. 2016, reported detrimental effects of dissociated NMC on aquatic microorganisms.1 In the first part of this project, the objective was to explore and develop an effective method to measure nickel (Ni) and cobalt (Co) concentration spectrophotometrically. This step was crucial for the second part of the project, which was to quantitatively analyze the…

    Introduction: Corrosion, otherwise called rusting is defined as a natural process that changes over a refined metal to a more chemically stable shape, for example, its oxide, hydroxide, or sulfide. It is the slow destruction of materials (generally metals) by a chemical reaction caused by the environment. Corrosion is basic to ponder in two perspectives. Right off the bat, financial, which including the lessening of material misfortunes coming about because of the squandering ceaselessly or…
