George Orwell’s novel‚ 1984‚ portrays a chilling picture of how the power of the state could dominate the lives of individuals through cultural conditioning. The Party controls every aspect of life and sets strict guidelines. Every inner and outer party member has to worship Big Brother unless they are a prole. Proles are the lower class part of society. Winston is an outer Party member and works in the fiction department fixing history and the Party’s faults. Winston feels frustrated by the

Experiment V02 An analysis of aspirin tablets Procedure a. Weigh accurately a definite number of aspirin tablets (two or three tablets weighing no more than 1.5 g) into a 250 cm3 conical flask. Initiate the hydrolysis of the aspirin by adding 25 cm3 of 1.0 M sodium hydroxide by pipette‚ diluting with approximately the same volume of distilled water. Warm the flask over a tripod and gauze for ten minutes to complete the hydrolysis. b. Cool the reaction mixture and transfer with washings to

BACKGROUND: Esterification is a reaction that combines an alcohol with an organic acid‚ with a water molecule is being taken out‚ and an ester is formed. A concentrated acid catalyst speeds up the esterification. In this experiment set up‚ sulphamic acid was used‚ as it is a solid acid and be added dry‚ without any water‚ which is a reactant in this experiment equilibrium. Esterification is a slow and reversible reaction. The equation for the reaction between an acid RCOOH and an alcohol RẬᶦ

Objective To determine soluble solid concentration in some fruits including tropical and temperate fruits by using handheld refractometer. Introduction “Sugar are the major soluble in fruits juices and estimate of sweetness. Other soluble materials include organic and amino acids‚ soluble pectins‚ and others. Soluble solid concentration can be determined in a small sample of fruits juice using a hand held refractometer. The measurement must be made at 20°C to get an accurate value. This instrument

Determination of the Enthalpy for Decomposition of Hydrogen Peroxide Objective: To construct a coffee cup calorimeter‚ measure its calorimeter constant‚ and determine the enthalpy of decomposition and formation of hydrogen peroxide. Background: This experiment is a classic thermodynamics lab. In it‚ we attempt to measure the enthalpy (H) of a chemical reaction. The main obstacle is that this is a quantity that cannot be measured directly. It instead is observed as heat from one substance is transferred

BROWNIAN MOTION 1. I NTRODUCTION 1.1. Wiener Process: Definition. Definition 1. A standard (one-dimensional) Wiener process (also called Brownian motion) is a stochastic process {Wt }t≥0+ indexed by nonnegative real numbers t with the following properties: (1) (2) (3) (4) W0 = 0. With probability 1‚ the function t → Wt is continuous in t. The process {Wt }t≥0 has stationary‚ independent increments. The increment Wt+s − Ws has the N ORMAL(0‚ t) distribution. A Wiener process with

Between 600 BCE and 600 CE‚ the development of a strong centralized authority is a cause to the unification of Chinese warring states and the subsequent rise of the Qin Dynasty. An effective bureaucracy in the Qin state was used as a tool of centralization to subordinate the aristocracy. With the removal of multiple local authorities‚ the Qin state quickly developed their economy and formed a stronger military. Merchants no longer had to worry about varying local taxes and regulations thereby increasing
