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

this separation in crude oil is known as fractional distillation. Fractional distillation is carried out by heating the petroleum to 400 °C. As every hydrocarbon in petroleum has it a particular boiling point‚ by doing so‚ they will separate out and then be collected. The portion that remains thick at 400 °C falls to the bottom of the tower is removed and forms bitumen or asphalt. The mixture of vapours that enters the fractional distillation tower starts to condense as the temperature cools the

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

Tuber and corm rot Tuber infections are characterized by patches of brown to purple discoloration on the potato skin. Cutting just below the skin reveals a dark reddish brown‚ dry corky rot. Heavy infection can give rise to total loss of the tubers. Light infections can occur and are difficult to detect.

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

There can be multiple causes for tragedy in stories or plays. One that stands out happens to be the dangers of isolation. In the tragedy known as Othello‚ this theme causes great conflict leading to the story or play ending tragically with many deaths. Not only does isolation allow Iago to go through with his evil plan‚ but it also makes Othello question his wife and grow hatred for Cassio. Othello is heavily busy with military duties giving Iago a big opening to talk to people behind his back

antibiotic treatment. Teaching infection control through learning of isolation precaution can decrease the spread of infection in critical care units. The goal of this project is to ensure each person understands the different isolation precautions and practices to minimize the spread of these bacteria to staff‚ visitors and other patients in this unit. Nurses can educate and reinforce protocols to those individuals who need further teaching regarding isolation. The overuse of antimicrobial agents is

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
