| Separation of Nitrophenols | | | | Abstract: Using a micro scale steam distillation we separated ortho and para-nitrophenol from a mixture that was already made. After the para and ortho were separated we measured their melting points and compared it to the literature values for purity. For ortho-nitrophenol we had 60% recovery and for para 160% recovery. Our melting point ranges were ortho: 45-46°C and para 64-95°C. Introduction: Nitration: In phenols‚ -OH group strongly

Pre-Lab: Analgesic drugs are known for reducing pain‚ while antiseptic drugs reduce symptoms such as fevers and swelling. However‚ some of these drugs can reduce both illnesses. To obtain a pure compound in these drugs‚ the scientist needs to separate the desired compound by taking advantage of the different physical and chemical properties. Such as; different boiling points

of communication. In my term paper I will critically analyze the intercultural communication that occurs in the film Six Degrees Of Separation. An important concept to understand in order to do this will be identity. Specifically‚ it will be important to understand the components of ascription and avowal‚ which together form an identity. Six Degrees of Separation is a 1993 film starring Will Smith as a sharp-witted con artist. Although I have not yet viewed this film‚ the subject of identity is

ESTPs are spontaneous‚ active folks. Like the other SPs‚ ESTPs get great satisfaction from acting on their impulses. Activities involving great power‚ speed‚ thrill and risk are attractive to the ESTP. Chronic stifling of these impulses makes the ESTP feel "dead inside." Gamesmanship is the calling card of the ESTP. Persons of this type have a natural drive to best the competition. Some of the most successful salespersons are ESTPs. P.T.

“The children and grandchildren of a whole nation of dreamers…….. have let our forefathers down.” Do you agree? The Bahamas is a great nation that has overcome many obstacles in the past; there are many men and women that have sacrificed a lot for this country to be what it is today. However‚ according to Nicolette Bethel in her text “On Independence”‚ she states “instead of aiming for stars‚ we turn our backs on them because to reach that high might cost too much”. Bethel’s quote is expressing

Abstract By separating chemicals out of a mixture and purifying them through sublimation and recrystiliation‚ changes in the substances physical properties can be shown. A salicylic acid-naphthalene mixture was mixed together with diethyl ether and saturated sodium bicarbonate. Two layers separated and were extracted after acidifying with HCl. This precipitated the crude salicylic acid. The left over mixture was combined with water and the two layers separated where crude naphthalene was recovered

Ecosystems Components SCI/256 A region that receives fewer than 10 inches of rain annually is considered a desert. This lack of precipitation loosely illustrates what encompasses the desert ecosystem. Although there are many cold deserts around the globe‚ for the purpose of analysis‚ the focus of this paper will be hot desert ecosystems. The extreme heat of the day in some deserts can reach above 120 degrees and drop down below 32 degrees (National Geographic‚ 1996-2013). These temperature extremes
