Chm235LL 2/18/14 Caffeine Isolation Lab I. Abstract Solid crude caffeine was extracted from tea and purified via sublimation. The melting point was experimentally found at 215.9-218.7oC. II. Introduction Caffeine is the most dangerous substance being used in lab this semester‚ but it’s also one of the most favorite chemicals commonly ingested among college students. The main purpose of this lab was to extract caffeine from a beaker of about 20 ml of tea. Sublimation was an effective and convenient

BREAKDOWN IN SOLID DIELECTRIC The requirements of good dielectric: o Low dielectric loss‚ o High mechanical strength‚ o Free from gaseous inclusions‚ and moisture‚ o Resistant to thermal and chemical deterioration. Solid dielectrics have higher breakdown strength compared to liquids and gases. When breakdown occurs‚ solids get permanently damaged while gases fully and liquids partly recover their dielectric strength. Breakdown mechanism varies depending

The Melting Pot The myth of the melting pot was created by a man named J. Hector St. John de Crèvecoeur. His idea was that immigrants from all over the world would come together to create a new society. A new race‚ religion and way of life would come from this society. The myth is widely known today and is often related to the United States. America is known to be a melting pot because it is a society made up from people of different race‚ culture and beliefs. The myth of the melting pot implies

First used by Israel Zangwill in a 1908 play‚ the term “Melting Pot” considers the American Dream‚ the incorporation and Americanization of immigrants in the American society. The melting pot derives from a process called assimilation‚ which consists of adoption of a host country’s cultures. This may imply sometimes the abandoning of some aspects of the ethnic culture of an individual (Zanca). The melting pot is an idea of “individuals of all nations melted into a new race of men‚” as J. Hector St

A solid argument consists of a claim‚ reasons/evidence and conclusion. “Reasons are beliefs‚ evidence‚ metaphors‚ analogies‚ and other statements offered to support or justify conclusions. When a writer has a conclusion she wants you to accept‚ she must present reasons to persuade you that she is right and show you why. You cannot determine the worth of a conclusion until you identify the reasons” (Browne & Keeley‚ 2012‚ p.28). Absent reasons or conclusion the argument is weak‚ unclear‚ pointless

(Acetylsalicylic Acid) Abstract:- Aspirin (acetylsalicylic acid) is produced experimentally in the lab. The resulting percentage yield is 65.5%. The purity of the obtained product is tested using the melting point and Ferric Chloride Test (FCT). The aspirin was massed‚ and the melting point was determined. Based on the data collected‚ there was a total yield of 1.757g of purified aspirin‚ which had a melting point range of 125°C-130°C. Results of the Ferric Chloride test showed that no unreacted salicylic
