  • An Analysis Of 'In Bed' By Joan Didion

    1219 Words  | 5 Pages

    When writing her personal essay “In Bed”, author Joan Didion intended it for an audience very familiar with migraines, however, it has the potential to be written for an audience of people just beginning to experience migraines. Didion’s use of personal anecdotes, factual information, and inspiring acceptance are all points that can be altered for this new audience. Didion begins her essay with personal accounts of her experiences with migraines, setting the stage for an introduction that relates

    Differential Association Edwin Sutherland Theory proports that through interaction with others individuals learn values, attitudes, techniques, motives for criminal behaviour. Two different cultures exist, with one being criminal and the other conventional. Normal learning occurs through verbal and non verbal communication that helps to establish whether attitudes of individuals is favorable to law violation through normal learning processes by individuals who are disposed towards breaking the

    Lab report: How does the surface area affect the rate of reaction ? Introduction The rate of a chemical reaction (or reaction rate) is a calculation of the total time needed for a reaction to take place, or how quickly the reactants are transferred into products in a chemical process. This rate can be measured in two methods. The first one is to measure the rate at which the reactants are used up per unit of time, while the second method is to measure the rate at which the products are formed

    Introduction In the following lab experiment, reactions will be induced in order to experimentally determine both the rate laws and the reaction orders of hydrochloric acid and sodium thiosulfate in the synthesis of the two solutions. A rate law is an equation which can tell you how fast a reaction will take place, dependent on the concentrations of each solution involved. A reaction order, usually described as either zeroth, first, or second order, gives the magnitude of variance when the concentration

  • Meeting The Three Graces Analysis

    821 Words  | 4 Pages

    Meeting (The Three Graces) is an oil on canvas painting created by Manierre Dawson in 1912. Cubistic in style, the subjects of his painting are three women from Greek mythology commonly known as the three graces. The women were daughters of Zeus who represented traits such as youthfulness, elegance, and beauty. There have been many artworks depicting the three graces, but Manierre Dawson’s stands out from the rest. Dawson’s painting is different from traditional portrayals of the graces because of

  • Observation: The Lost Dog Restaurant

    780 Words  | 4 Pages

    My observation took place at The lost dog cafe and my focus was mainly on the host welcoming customers. I started my observation at 6 pm and it took me two hours to complete my assessment. I was sitting at an high top chair right at the front of the restaurant which limited my eyesight to the back part of the restaurant. I decided to sit up front since I assumed the host would be standing at the front of the restaurant but soon I found out that she occasionally went to the back part on the restaurant

    The Relationship between Molecular Weight and the Rate of Diffusion of Substance Anthony Earl D. Cristobal Group 1 Sec. U-7L 16 October 2014 Abstract The relationship between the molecular weight and the diffusion of the substance was determined using two laboratory experiments. In the first experiment, a horizontally placed glass tube was set. Two cotton balls were soaked in hydrochloric acid (HCl) and ammonium hydroxide (NH3). At the same time, the cotton balls were inserted

    1. For the demo experiment, the balanced chemical equation is as follows: (NH4)2Cr2O7(s)=Cr2O3(s)+N2(g)+4H2O(g). After the lightning of Ammonium dichromate, Chromium (III) oxide was formed while the Nitrogen and Water escaped into the atmosphere in a gaseous phase. Ammonium dichromate((NH4)2Cr2O7) gave rise to Chromium (III) oxide (Cr2O3), Nitrogen Gas(N2) and water (H2O) In terms of microscopic level, the ratio between reactants and products is as follows. One mole of Ammonium dichromate will give

    equilibrium was developed after Berthollet (1803) found that some chemical reactions are reversible. For any reaction mixture to exist at equilibrium, the rates of the forward and backward (reverse) reactions are equal. In the following chemical equation with arrows pointing both ways to indicate equilibrium, A and B are reactant chemical species, S and T are product species, and α, β, σ, and τ are the stoichiometric coefficients of the respective reactants and products: α A + β B ⇌ σ S + τ T The

    856 Words  | 4 Pages

    Arrhenius equation is a mathematical expression which illustrates the effect of temperature on the rate of a chemical reaction and is used to calculate reaction-rate constants\cite{logan}. In the equation, we have $k$ as the reaction-rate constant, R as the thermodynamic gas constant, A as the pre-exponential factor, E$_a$ as the activation energy and finally $T$ as the absolute temperature. Generally, the equation is represented in exponential form: \begin{equation} k = A \exp[-E_a/RT]

These two values completed the Table of Thermochemical Equations given and with respect to Hess’s Law, the heat of formation of solid NaCl was computed by adding the enthalpies in the table. Two Styrofoam cups and a thermometer through its lid served as the calorimeter where the reactions took place. Using the heat transfer equation, the enthalpy of the first reaction was computed to be -1.080 kJ/mol. On the other hand, the enthalpy of the second
