Dissociation Model of Prejudice suggests that processing information about others occurs in two-step: the first step triggers the stereotypes automatically‚ and the second step is that people have the control whether to accept the stereotype or not. By this theory‚ people cannot control the acceptances of the stereotype if they are distracted or not paying attention. Dissociation Model gives a cognitive explanation of the source of being

Introduction Spectrophotometer is an optical instrument that measures and shows how much light energy is transmitted by a substance in solution at different wavelengths of radiant energy. Light passes into a monochromator where only a very narrow range of wavelengths can pass through. From there‚ light is transmitted through a sample solution‚ and on to a phototube where the light energy is converted to an electric current that is registered on a meter. To measure the amount of light absorbed

Acid-Base Titration Using a pH Meter Bradley Holloway and Jennifer Parker Period 6 April 16‚ 2013 Introduction: In chemistry‚ the ability to find molarities of acidic and basic solutions is a convenient way to convert between moles of solute and the volumes of their solutions. Through the process of titration‚ the molarity of these acids and bases can be found to a high level of precision. To begin titration‚ one solution is added to a second solution slowly until a certain point

Standardization of NaOH and Determination of Unknown Acid KEYWORDS: quantitative analysis‚ titration‚ buret‚ endpoint‚ standardization‚ half-equivalence point‚ calorimetric titration‚ potentiometric titration ABSTRACT: The concentration of sodium hydroxide was determined by colorimetric titration‚ and the identity of an unknown acid was determined by potentiometric titration. In the first titration‚ a strong acid standard‚ potassium hydrogen phthalate (KHP)‚ was used‚ to determine the concentration

health field there are many types of mental disorders. One that people are not aware: is called dissociation disorder. It is easy to be confused by the multiple definitions of dissociation disorder. It is important to explain the branches‚ types‚ diagnosis‚ and treatment of a dissociation disorder to understand what it is to suffer with a disorder of this severity. The three main branches of dissociation are Dissociative Amnesia‚ Depersonalization/Derealization‚ and Dissociative Identity Disorder (DID)

Abstract A spectrophotometer’s purpose is to use colors of the light spectrum to determine the concentration of light absorbing molecules in a solution. (p.59) In this particular lab‚ our mission was to determine the protein concentration and the standard curve of the unknown sample of BSA. This‚ by preparing five dilutions of

DETERMINING AN EQUILIBRIUM CONSTANT CAUSION 1. Potassium thiocyanate (KSCN) is hazardous 2. Wear protective material before performing the experiment. INTRODUCTION This experiment outlines the techniques necessary to determine the equilibrium constant for the formation of an iron(III) thiocyanate complex ion (FeSCN2+) from Fe3+ and SCN- . The quantitative preparation of several solutions and subsequent measurement of the solution absorbance using a spectrophotometer are the techniques that will

Determination is a positive emotion that involves persevering towards a difficult goal in spite of obstacles.[1][2] Determination occurs prior to goal attainment and serves to motivate behavior that will help achieve one’s goal. Empirical research suggests that people consider determination to be an emotion; in other words‚ determination is not just a cognitive state‚ but rather an affective state.[3] In the psychology literature‚ researchers have studied determination under other terms‚ including
