article I chose is called‚ “Synthesis of a Genius” by George Kauffman and Steven Chooljian. The area of exploration and discovery that I chose was the synthesis of urea in chemistry. Urea was discovered by Friedrich Wohler‚ in 1828. This discovery ultimately changed the belief at the time that only organic compounds can be created from living organisms. He was able to create urea (which is mostly what is found in human and animal urine) in the lab with inorganic compounds. The interesting thing

corresponding percentage yield. Extractions are a way to separate a desired substance when it is mixed with others. Extractions use two immiscible phases to separate the substance from one phase into the other. Typical lab extractions are of organic compounds out of an aqueous phase and into an organic phase. The distribution of a solute between two phases is an equilibrium condition described by partition theory. In this extraction‚ tea leaves are boiled in anhydrous sodium carbonate solution to extract

I. I haven’t heard of FFP during the first semester actually. I just knew that the following semester I would be needing a white book with a flame print on it. I really didn’t care about the subject so much even though I was already attending the classes. To tell you the truth‚ I thought that FFP would be the simplest subject in my load but as it turns out‚ it proved to be quite stressful. Not bad stressful but good stressful‚ okay‚ maybe sometimes bad stressful. I learned a lot of values from this

COMPARATIVE INVESTIGATION OF ORGANIC COMPOUNDS Abstract Organic compunds were examined to a comparative investigation to differentiate the properties of each sample. The physical state at room temperature‚ odor and color of the sample were noted by simple observation. In terms of solubility in H2O‚ 5% NaOH solution and 5% HCl solution‚ the samples were classified as to miscible‚ slightly immiscible or immiscible for liquid; and very soluble‚ soluble‚ partially soluble or insolubse for solid.
