Intact Dilation and Extraction Intact dilation and extraction which is also known as intact dilation and evacuation‚ intrauterine cranial decompression and most commonly but controversially known as partial birth abortion has created ethical waves in medicine over the years. This specific procedure has been a primary focus of many politicians and religious groups although it only makes up approximately .08% of abortions‚ or approximately 1‚032 per year‚ based on research done in the year 2006

Separating Acids and Neutral Compounds by Solvent Extraction Introduction The purpose of this experiment was to use solvent extraction techniques in order to separate a mixture consisting of a carboxylic acid (p-toulic acid)‚ a phenol (p-tert-butylphenol)‚ and a neutral compound (acetanilide). Extraction is the process of selectively dissolving one or more of the compounds of a mixture into an appropriate solvent‚ the solution that contains these dissolved compounds is called an extract (Manion

Chem 231: Organic Chemistry Lab EXPERIMENT #2 and #3 Extraction and Evaporation Recrystallization and Melting Point Measurement PURPOSE: 1. To the components of a simulated pharmaceutical preparation‚ Panacetin‚ and identifying the unknown component of the mixture through extraction and separation methods. 2. To learn how to purify by recrystallization‚ how to dry them and how to obtain a melting point. PRECAUTION: ACETANILIDE AND PHENACETIN ARE EYE AND SKIN IRRITANTS. Minimize

Germany in the 16th century‚ the first use of steam locomotives was in Britain. Its earliest "railways" were straight and were constructed from parallel rails of timber on which ran horse-drawn carts. This development was all due to steam engines. They were one of the many innovations of the Industrial Revolution and allowed boats and trains to run on steam. A major component of the steam engine was coal. Coal was used to create the steam for the steam engine and was a very important source of fuel

EXTRACTION OF COPPER FROM OXIDISED COPPER ORE Aim: To analyse how copper is obtained from oxidised copper ore using the processes of leaching‚ solid-liquid separation‚ displacing and electrowinning. Method: Refer to ‘Extraction of Copper from oxidised Copper Ore’ document pages 1-2 Results: Leaching: The blue particles in the copper ore which is copper was dissolved in the sulphuric acid and the solution turned into a blue colour. There was also sediment that was floating around

2-15-11 Purpose: The purpose of this experiment was to take spinach leaves and extract the chlorophyll and carotenoid pigments by using acetone as the solvent. The chlorophyll and carotenoid pigments were extracted by using column chromography and alumina was used as the solvent. Solvents of different polarities were used‚ starting with the least polar‚ to extract the certain components from the leaves. They were then analyzed by using thin- layer chromatography. Procedure: The first part
