Gay/Lesbian Families Adoption is an extremely sensitive subject‚(insert dash) especially for individuals who are Gay or Lesbian. There is much controversy on the topic. There are a variety of ways to which it isn’t possible for a couple to adopt. Infertility is becoming a greater problem in our time. In Gerald P. Mallon’s article‚ “Assessing Lesbian and Gay Prospective Foster and Adoptive Families: A Focus on the Home Study Process‚” in 2007. He introduces a few different ways gay men and lesbian

Quitay Morris Jake N. Professor Rafie Paz ENGL 1013 July 29 2013 Why are Teenagers so Lazy Today? The youth is the hope of the nation. That is the sentence that defines what the teenagers’ worth to the country is. We are supposed to change what the country is now. But the question is . . . Can we? From what I observed is happening now‚ instead of being the country’s biggest hope‚ we seem to be one of its burdens. There’s pre-marital sex‚ prostitution‚ juvenile delinquencies‚ and the list

Synthesis of Acetanilide By: Rick Whitely April 9‚ 2013 Organic Chemistry Lab 1; Professor J. Hutchison Recrystallization is a common method of purifying organic substances through the differences in solubility at different temperature. In this experiment‚ acetanilide was produced by acetylation of aniline with acetic anhydride. The crude acetanilide was dissolved in a solvent in a heated water bath. The solution was cooled slowly in an ice bath as crystals form out. As the compound crystallizes

The polar oxygen accepts the electrons from now positively charged hydrogen. The positively charged sodium disassociates leaving the hydroxide ion with a negative Scheme 1 shows the mechanisms that were demonstrated during the synthesis of Aspirin. charge that attracts to the positively

acidification of salicylic acid and acetic anhydride. The objective was to convert a specific amount of salicylic acid into the same amount of aspirin that was high in purity. Furthermore‚ the other objectives were to enable students to conduct the synthesis of aspirin‚ reinforce skills or recrystallisation and the technique of melting point determination. The amount of each compound should be the same because there is a 1:1 ratio between them. The purity of the synthesized aspirin was measured by determining

Name Period Date The Synthesis of Aspirin Background Pharmaceutical research labs perform chemical reactions between organic molecules that contain mostly carbon. Since the atoms in organic molecules tend to be nonmetals‚ then the bonds that hold them together are covalent bonds. Only a few elements on the periodic table are nonmetals: C‚ N‚ O‚ S‚ Cl‚ and F. This small number of elements can be bonded together in different quantities‚ bonding types (single‚ double‚ triple bonds)‚ and structural

Lab Report Synthesis and Characterization of Aspirin (Acetylsalicylic Acid) The Synthesis and Characterization of Aspirin (Acetylsalicylic Acid). Summary: In this experiment‚ we produced 4.21 g of acetylsalicylic acid. Our theoretical yield was calculated to be 5.22 g. Therefore our % yield was determined to be 80.6%. The experimental boiling point range of acetylsalicylic acid was found to be 130-132° C. The true melting point of acetylsalicylic acid is 135° C‚ therefore our percent

Abstract – This multi-step synthesis uses aniline as the starting reagent to synthesize five compounds employing several reactions such as acetylation‚ diazo coupling‚ nitration‚ bromination‚ and hydrolysis. The isolated products were analyzed with TLC and spectral data that determined most products were pure while some had a few impurities indicated by GC‚ LC‚ and a wide melting point range was shown for products 2 and 3. The presence of water in product 2 and 7 was indicated by the IR. Acetanilide
