A Report of Experiment 1 Purification and Identification of An Unknown Mixture Aim To separate a mixture of a neutral (ester‚ alcohol‚ ketone‚ aldehyde or ether) and an acidic compound (phenol or carboxylic acid) or a neutral and a basic compound (amine)‚ and to identify the unknown mixture by physical (M.P. or B.P.) and spectroscopic methods (NMR‚ IR and MS). Method The mixture (sample number: 27) was dissolved in 200 mL of CH2Cl2 and then extracted with 10% NaOH. The acid was removed

The fundamental attribution error a more common name for the correspondence bias is defined as the tendency of people to make dispositional attributions for others behaviors. (Duff‚ 2012) For example‚ if a cashier failed to smile at you while checking out at the store‚ you might assume that they are just miserable and rude. You wouldn’t take anything else into consideration. You’d be judging their behavior based “who they are” rather than taking situational factors into consideration. The observations

Rosenhan experiment The Rosenhan experiment was an experiment into the validity of psychiatric diagnosis‚ conducted by David Rosenhan in 1973. The study is considered an important and influential criticism of psychiatric diagnosis. Rosenhan’s study was done in two parts. The first part involved the use of healthy associates who briefly simulated auditory hallucinations in an attempt to gain admission to 12 different psychiatric hospitals in five different states in various locations in the United

EXPERIMENT 7: PERCENTAGE OF OXYGEN IN KClO3 Introduction: In this experiment you will determine the percentage of oxygen in potassium chlorate. You will calculate the theoretical value from the chemical formula and compare your experimental value to the theoretical value. Background: When potassium chlorate (KClO3) is heated‚ it undergoes chemical decomposition. Oxygen gas (O2) is given off and potassium chloride (KCl) remains as the residue. The equation for the decomposition of potassium

Shock Shock is a syndrome characterized by decreased tissue perfusion and impaired cellular metabolism. This results in an imbalance between the supply of and demand for oxygen and nutrients. The exchange of oxygen and nutrients at the cellular level is essential to life. When a cell experiences a state of hypoperfusion‚ the demand for oxygen and nutrients exceeds the supply at the microcirculatory level. Classification of Shock The four main categories of shock are * cardiogenic‚: *

Abstract:Conjugation is a natural occurring process that involves the transfer of DNA from one cell into another through a physical connection between the cells. In the following experiment‚ two strains of Escherichia coli bacterial cells (donor F’lac+strs and recipient F-lac-strr) underwent conjugation to produce a transconjugant strain (F’lac+strr). MAC plates and streptomycin were utilized to determine if conjugation had occurred. When plated‚ the donor colonies appeared red and the recipient

Analysis of Reasons of Attack on Friction Ridge Evidence In 1993‚ Daubert’s tests were introduced after the ruling of Daubert v. Merrell Dow Pharmaceuticals and used until now. It considers deeper on the evidential reliability. Under Daubert‚ Judges contribute more in the decision-making of the admissibility of scientific evidences. In Daubert and later cases‚ the Court explained that the federal standard includes general acceptance‚ but also looks at the science and its application. Trial judges
