experiment‚ the hood in the lab was used. The curds were placed in a 100 mL beaker and extracted using 30 mL of ethyl acetate. The curds were crushed with a stirring rod. This extraction was then gravity filtered through a funnel fitted with the filter paper. A rubber policeman was used to scrape the beaker to get as much casein as possible. This casein was then put aside in the hood safely. Boiling chips were put into an Erlenmeyer flask along with the filtrate collected. This flask was then put inside

Although media producers would avoid admitting to portraying women in such a way‚ Katha Pollitt in the “Smurfette Principle” clearly agrees and states; “I came across not a single network cartoon or puppet show starring a female” (545). Through the examples of various children’s television shows‚ Pollitt argues that women are minor to men and that even children are catching onto the media’s feminist ways. Pollitt then discusses what she calls the “smurfette principle” which is when a certain male character

Introduction In this lab‚ caproic acid was synthesized in a multi-step process that involved the synthesis of three intermediates – diethyl n-butylmalonate‚ potassium n-butylmalonate‚ and n-butyl malonic acid respectively. An IR was used to characterize the starting material‚ n-bromobutane‚ and the first intermediate‚ diethyl n-butylmalonate; while IR and NMR were used to characterize the final product‚ caproic acid. Reactions‚ Mechanism and Theory Caproic acid a.k.a n-hexanoic acid is a carboxylic

Synthesis of Aspirin and Tylenol Kyla Wykoff Abstract Aspirin and Tylenol were synthesized by means of crystallization‚ recrystallization‚ and melting point determination. Synthesis produced significantly high percent yields for aspirin‚ however‚ produced extremely low and impure percent yields for Tylenol. A second group was also used to compare results and errors‚ in which they too were also producing extremely low percent yields of Tylenol. Therefore‚ error was based on the specific protocol

about a lot more of different things that all together come as one thing‚ and it means things are not what they seem. There’s more to everything than meets the eye. [S]He thinks in a much bigger perspective. He provides an excessive amount of examples. Examples that talk about things we can’t do if we were as small as ants compared to human size. And how he says many generations could have been born and died before a minute passes on Earth. It’s extraordinary that something like that could happen

beliefs. All our life‚ we perceive knowledge and information through different forms of language. Hence‚ our perspective is also limited by the language. Language is one of the unique things that people have. Language puts limits on our thoughts. For example‚ when someone says dog‚ we all picture a different dog‚ therefore we perceive the information differently. Similarly‚ religious books influence the way of our thinking through the words or language in the book. Those words are ideas of someone else
