Bankruptcy: Its Prediction and Accounting Indicators One major assumption in accounting is the Going Concern. It states that an accounting entity is viewed as continuing in operation indefinitely‚ thus‚ financial statements are normally prepared in the assumption that the entity will continue its operations for the forseeable future. But then it is inevitable that one shall come to an end. So if there is evidence that the entity’s operations are to be terminated‚ the going concern assumption

Synthesis of DEET Abstract: For this experiment m-toluic acid was reacted with thionyl chloride resulting in a nucleophilic acyl substitution which could then be used to create DEET with excess diethyl amine (Figure 1). This was done by adding diethyl amine drop wise using a seperatory funnel which resulted in a gas formation which was controlled with a condenser attached to a gas vacuum. The resulting mixture was then washed to remove excess acids and bases and rotovapped. DEET was synthesized

Synthesis of Cyclohexanol Author: Ahmed Ayyash 06/06/13 Introduction: In this experiment‚ cyclohexanol was prepared from an initial cyclohexene. However‚ this occurred over a number of steps‚ these are out lined below. 1. Cyclohexene + aqueous acid cyclohexyl cation 2. cyclohexyl cation + hydrogen sulphate + water protonated cyclohexanol + cyclohexyl hydrogen sulphate 3. cyclohexyl hydrogen sulphate protonated cyclohexanol + HSO4 4. protonated cyclohexanol + HSO4

result in criminal charges being filed. If carried out by individuals unskilled at chemistry they could result in serious bodily harm. MDMA ("Ecstasy") is a semi-synthetic compound which can be made relatively easily from available precursors. Synthesis instructions exist which can be followed by an amateur with very little knowledge of chemistry. However‚ people with less than 2 years of college chemistry experience would probably not be capable of sucessfully synthesizing MDMA‚ and would either

The polar oxygen accepts the electrons from now positively charged hydrogen. The positively charged sodium disassociates leaving the hydroxide ion with a negative Scheme 1 shows the mechanisms that were demonstrated during the synthesis of Aspirin. charge that attracts to the positively

Social scientists have studied it‚ lawyers have tried to fix it and post-feminist society is over it. But women are still outnumbered by men in math‚ science and engineering fields. Most overt discrimination against women in the sciences has been reduced or eliminated in recent decades through legal‚ academic‚ corporate and government measures. But a climate that is less than fully friendly to women remains‚ and its texture is often still so taken for granted that it tends to be invisible. The

SYNTHESIS OF ESTERS USING GREEN AND NON-GREEN CHEMISTRY Abstract Esters are a class of organic compounds with the general formula RCOOR’. Ester also contributes the flavor and aromas in fruits and flowers. The esterification reactions will use in the procedure‚ which are the interaction of a carboxylic acid with an alcohol‚ aided by an inorganic acid catalyst (H2SO4). Moreover‚ the green method will not use any catalyst but using heating source instead (microwave). Based on the comparison of

Gay/Lesbian Families Adoption is an extremely sensitive subject‚(insert dash) especially for individuals who are Gay or Lesbian. There is much controversy on the topic. There are a variety of ways to which it isn’t possible for a couple to adopt. Infertility is becoming a greater problem in our time. In Gerald P.
