After comparing the class data that consists of the percent compositions of Cyclohexane and Toluene using the different types of distillation, I think the most efficient method is packed. The 4th fraction for packed contained an average of 6% Cyclohexane and 94% Toluene while the unpacked contained 4.35% Cyclohexane and 95.65% Toluene. The simple contained 3.35% and 96.63%. The packed is the most efficient, because the glass beads that provide more surface area for condensation. The data also shows that the unpacked is more efficient than simple distillation. This can also be because of the long tube in unpacked that provides more surface area for more than one condensation like the simple distillation does.
In this experiment, we also encountered
an experimental error. Evidently, it important to maintain the rate of heating in any types of distillation. We had to do this throughout the experiment by removing the flame once in a while to prevent the rapid heating of the liquid before obtaining the fractions. We obtained a small amount of the first fraction maybe for this reason, and also because we didn't accurately determine the temperature at the end. In other words, we could have possibly got a little more of the liquid. Overall, this experiment illustrates the differences in the types of distillation, which can be helpful in determining which type to use for purifying various things.
Orgon and candide were two major characters from different books that were devoted to Tartuffe and pangloss respectively. Orgon was a man that followed Tartuffe blindly and candide was a devoted student of pangloss. Orgon and Tartuffe both depended on Tartuffe and pangloss to the point of folly.
In order to separate the mixture of fluorene, o-toluic acid, and 1, 4-dibromobenzene, the previously learned techniques of extraction and crystallization are needed to perform the experiment. First, 10.0 mL of diethyl ether would be added to the mixture in a centrifuge tube (1) and shaken until the mixture completely dissolved (2). Diethyl ether is the best solvent for dissolving the mixture, because though it is a polar molecule, its ethyl groups make it a nonpolar solvent. The compounds, fluorene and 1, 4-dibromobenzene, are also nonpolar; therefore, it would be easier for it to be dissolved in this organic solvent.
The solvent should be easily removed from the purified product, not react with the target substances, and should only dissolve the target substance near it’s boiling point, but none at freezing. A successful recrystallization uses minimum amount of solvent, and cools the solution slowly, if done to fast, many impurities will be left in the crystals. Using the correct solvent, in this case ice water and ethyl acetate, the impurities in the compound can be dissolved to obtain just the pure compound. A mixed solvent was used to control the solubility of the product. The product is soluble in ethanol an insoluble in water. Adding water reduced solubility and saturates the solution and then the crystals
In a land that was being reshaped by American expansion, stood two men, who would fight to save their lands and tribesmen. Cochise and Crazy Horse were among the fiercest and bravest Native Americans that have ever lived. These two men, while having clashing personalities, both showed strength and courage, in their pursuit to remain free.
There were many European people that decided to come to America to gain new territory. These people included Spanish explorers such as Christopher Columbus and Hernan Cortes and English explorers such as John Cabot. All three of these explorers sailed to America in between 1490 and 1550. They helped create the country that we live in today and changed the culture of America drastically. Christopher Columbus first voyaged in 1492 thinking he was sailing to Asia. He wanted to trade with the natives for spices and gold but he also wanted to convert them to Christianity. John Cabot like Columbus was trying to find a water route to Asia but landed in Canada instead. Cabot was an English sailor looking for trade routes and trying to find new lands
The purpose of this report is to explore the controversial dispute between the quality of two different forms of fish oil supplementation; Triglyceride (TG) and Ethyl Ester (EE). Fish oil can be implemented into a diet by eating either fish or taking supplements. Fish oil is extracted from selected fish that contain highly beneficial healthy oils known as omega-3 fatty acids, two of the most important omega-3 fatty acids that are found in fish oil are Docosahexaenoic Acid (DHA) and Eicosapentaenoic Acid (EPA). Some of these fish that contain healthy omega-3 fatty acids include Tuna, Salmon, Mackerel, Herring, Anchovy’s etc. Fish oil supplementation also often contains small amounts of vitamin E to prevent spoilage and is can be combined with various other minerals and vitamins. There is an array of benefits that are involved when implementing fish oil into a diet; although it’s most common association is that it has been linked to slightly lowering blood pressure or triglyceride levels (fats linked to cholesterol). Although fish oil is recommended for persons with high blood pressure, it’s extremely important to remember that it is only to be taken at recommended dosages as it can ironically increase the chances of stroke when overdosing on the supplement. The scope of this report includes a general comparison between TG and EE fish oil supplements and how they are chemically differentiated, with a focus on how the quality of the two forms of supplement are processed. This report will not focus on other forms of fish oil sources and the impact it might have on irreversible factors such as age, gender, genetics, race/culture or environmental conditions.
water than last time, less products were formed, and most of the ester was used
What makes Grease and Footloose an all-time classic musical film to watch is the way they easily appeal to teenagers then to teenagers now. The catchy tunes, stunning john Travolta in grease, same relatable plots in footloose, along with the wild dance moves in both movies is what makes these two films ironically very similar. Both of the main protagonists in this movie move to new areas, where new influences effect not only their teen romance, yet as well as affect their ability to avoid unwanted people and the sense of being and outsider. However, grease and footloose are taken place in a high school setting where the relationships of each individual is changed due to the social influences brought by their peers. The relatable struggle of peer pressure in today’s society is exactly the same struggles portrayed in the past and in which is shown vividly in these to movies. Peer pressure was inevitable to all the characters; grease showed how the negativity of peer pressure effected Danny and Sandy while Ren and Ariel in footloose showed how peer pressure can have a positive influences throughout their relationship.
People have often pondered the reasons for the greatness of Edith Wharton's novel, Ethan Frome. What is it that causes this story to be considered an all-time American classic? One journalist quotes a humanities professor at MIT who states that, "We turn to Wharton because the truths she tells are a bracing tonic in a culture steeped in saccharine sentimentality." The journalist goes on to describe the typical, "popular" story and how they often have endings where "romantic ideals are magically fulfilled..." There is much more to Ethan Frome than simply an unhappy ending to contrast with the many other stories that have sugar-coated and sanguine endings. At first glance, the ending of Ethan Frome may appear to be only depressing. In truth, Wharton offers the reader a complex ending through the careful incorporation of poetic justice and irony.
After the oil/gas mixture is drawn from the ground, it is then stored into a storage tank and allowed to rest for a while. Then the gas is piped off to a set of distillation columns to clean up the ethane. In order to activate the chemical reaction necessary to separate the ethane, a thermal cracking unit (a sort of long heated tube) i.e. a plug flow reactor is used. After a series of distillations, ethylene exits the tube.
In the two books name Candide and Americanah, love can’t be achieved easily by Ifemelu and Candide because they must separate from their love ones and encounter on a long journey to unit with their love ones again. For instance, in the book name Candide, Candide is forced to separate from Cunegonde by being banished out of the baron’s castle for secretly kissing each other. Similarly, this happens when Ifemelu is forced to separate from Obinze to take care of Dike while Obinze has to move to London to finish pursuing his degree in college. This circumstance in both characters results them to pursue in their long journey to unite with their love again. The use of characterization and symbolism helps to establish the journey made by both the main protagonists to achieve the unity of love with Obinze and Cunegonde.
On the contrary, the Norton version of Medea paints one of the strongest women in Greek society. When reading the Norton version, there is an insatiable thirst to read what Medea will say next since she has a technique of persuasion that is unrivaled by any woman in the play. All the more so supporting this is the legendary Creon himself admits to Medea, “Your words are soothing, but I’m terrified of what’s in your mind.” (Norton, 753). When the notorious ruler Creon can agree that the words are soothing, but terrifying, one must know that the language is far more cunning than simple animalistic urges.
The poem ‘Fable of the Bees’ and the novella Candide both comment on the state of European society of the time. In Fable of the Bees, Bernard Mandeville uses a fictional bee society as a metaphor for how he believes European society ought to function. Voltaire uses satire in Candide to reveal the wrong he sees in society as a whole, and what he feels constitutes the best possible society. Both Mandeville and Voltaire wrote in eighteenth century Europe, at the height of the Enlightenment era. Their descriptions of European society are similar, yet how each thought the perfect society should be differ significantly. It is my opinion that the ideal society Voltaire depicts in Candide is fundamentally at odds with the best possible society envisioned
“With access to Fins brewing equipment and ingredient resources, and our long history of bending the normal guidelines using different grains and wood-aging techniques, we plan on distilling and aging all sorts of delicious spirits in the near and long term,” says Landis. “What we’re seeing is that consumers are looking for the same ‘goodness’ out of their craft spirits that have led them to explore craft beer,” says Distillery Manager Fred Thomas. “They want a high-quality distilled spirit and an honest and authentic approach wrapped in an interesting story.” Many distillers are buying bulk spirits from large distilleries and rebranding them, but our spirits are 100% scratch-made. We start with the best ingredients possible, brew them using the best equipment and processes, and then distill them in a manner that allows them to maintain the ‘goodness’ of all those delicious ingredients. Having this type of ownership and expertise over the
The catalytic process occurs at lower temperature anf offers higher selectivity but requires frequent regeneration of the catalyst. Then, the products are cooled and introduced into a pair of separators which separate the unreacted hydrogen. The unreacted hydrogen is compressed and recycle back to the feed and reactor. The products that leaving the separators are heated before introduced into a distillation column which the toluene is separated from the stream and recycle back to the...
