In experiment 5‚ distillation method was used to divide hexane and toluene from a mixture (50:50) of hexane and toluene. Hexane was separated from toluene and was observed from the gas chromatography‚ it showed that hexane increased from 0.0.873 to 0.886 moles. Once the mixture of toluene and hexane hit 70 degrees in the experiment‚ the distillate was used for the gas chromatography. Hexane was higher in the distillate stage. The first drop of condensation appeared at 79°C. The volume of the distillate

Methods of needs identification - the process The following paragraphs describe ten important steps in training needs identification and analysis. 1. Stakeholder analysis The topic on this subject (Part II - topic 2) clearly indicates how important it is to identify all possible stakeholders with an interest in the training process‚ including the identification and assessment of the training needs. Stakeholder analysis in the context of needs assessment will reveal the importance and possible

The purpose of this experiment was to isolate and purify cholesterol from egg yolks. Two hard boiled egg yolks were twice extracted with diethyl ether and methanol‚ with the filtrate collected via vacuum filtration. Potassium hydroxide pellets were added to the filtrate‚ the ether was distilled off‚ and the mixture was saponified by reflux. The crude cholesterol was isolated through a series of ether extractions and aqueous washes; then the ether was dried with MgSO4 and removed by rotary evaporation

Theory: Distillation is the conversion of a mixture of substance into vapors which is afterwards condensed to the liquid form. It cans separation or purification of substances by taking advantage of differences in volatility. The purpose of this lab is comparing the efficiency of two distillation methods with the mixture of ethanol and 1-butanol. in theory the fractional distillation should be more efficient because of the steel sponge. The sponge acted as surface area for gas to condense on. This

the never-ending search for energy sources‚ the invention of the steam engine changed the face of the earth." (Siegel‚ Preface) The steam engine was the principal power source during the British Industrial Revolution in the 18th century. The steam engine opened a whole new world to everyone. The steam engine maximized production‚ efficiency‚ reliability‚ minimized time‚ the amount of labor‚ and the usage of animals. The steam engine in all revolutionized the Eastern Hemisphere‚ mainly European

The Trifle Isolation Have you ever felt as though you were alone? Susan Glaspell wrote a play called Trifles. The story tells of the untimely death of Mr. Wright and the subsequent investigation. The investigation is being overseen by the county attorney‚ the sheriff and Mr. Hale who have brought their wives along to retrieve Mrs. Wright’s personal effects from the home. Everyone suspects Mrs. Wright of the death. The story has many themes but the one that stands out to me is isolation. This unfortunate

Organic Chemistry I Simple and Fractional Distillation The Simple and Fractional distillation experiment was divided into two parts. We split up the procedure in this experiment. My group did the simple distillation and we received the Fractional distillation from another group in class. In this experiment‚ we examined the effectiveness of fractional and simple distillation to determine which is more successful at extracting a pure sample. This experiment was very successful. We are able to

RESOURCE IDENTIFICATION Resource Identification Resource Identification Learning is a process that can be difficult or easy‚ depending on two main variables; the student and the available resources. These resources determine the learning curve of the student. Even if the student is intelligent and the learning tools are not sufficient‚ things may become difficult. Students should be able to get help whenever a difficult situation arrives. Easy access to these tools is key component for
