Organic chemistry

Chemistry is something that people use in everyday life. All the food we eat has to do with chemistry. Food has organic compounds that change when they are cooked. It is used in our everyday life when because you need chemistry to do everything. Stoichiometry is the relationship between the relative quantities of substances taking part in a reaction or forming a compound. The coefficients in a balanced chemical equation represent moles of reactants and moles of products. The mole ratio of…

The Chemistry of Emotions Even though we often think of our emotions as part of our own conscious, they are simply chemical reactions to stimuli in the mind, and depending on the event and who we are the chemicals released and emotions we perceive as result are always different.The emotions in our brain our vital to our survival. Emotions are simply the quickest way to get our body to react with the environment around it. For example, if we feel fear we are able to react to the oncoming…

Personal Statement The first day of high school chemistry was the beginning of shaping my love for pharmacy. I instantly fell in love with chemistry from this day. Already having a strong advanced mathematics background from middle school taking algebra, this tied into a lot of the chemistry components that I excelled in. Unsure of what to do after high school and to support myself financially, I joined the Army and served in the National Guard for six years. Becoming a single mother wasn't…

#1 Science major is one of my passions since I had taken Biology and Chemistry classes at high school. At that time, I have found myself significantly interested in remembering and understanding the morphologies and characteristics of animals, and microorganisms, as well as learning how the chemical substances are reacted or separated from each other. This passion continuously goes with me until I have attended to California community college. Before considering about the main major, I spend…

Newnham College, Cambridge, in 1938 and she studied chemistry. In 1941 she was awarded Second Class Honors on her finals, which was like a bachelor's degree qualifications for employment. She worked as an assistant research officer at the British Coal Utilisation Research Association. And during that time she studied the porosity of coal. The information she gathered she used as the basis for her 1945 Ph.D. thesis “the physical chemistry of solid organic colloids with special reference to…

by which various chemical substances combined with each other could be explained nicely if one assumed that chemical combination was the group together of atoms possessed of definite weights” (Chang 135). Thomas Thomson wrote in his history of chemistry “the atomic theory first occurred to Dalton during investigations of olefiant gas and carbureted hydrogen gas…Dalton found that if the amount of carbon was the same in each compound, then carburetted hydrogen gas contains exactly twice as much…

been interested in thiazolo[4,5-b]pyrazine core skeleton. Even though thiazolo[4,5-b]pyrazine has not been investigated in detail in the medicinal chemistry area, we have focused on it because of its structural similarity with thiazolopyrimidine (Figure 1). Thiazolopyrimidine core skeleton has shown various biological activities in the medicinal chemistry area such as kinase inhibitors,4 TRPV1 antagonists,5 E. coli and S. aureus SecA inhibitors,6 stearoyl-CoA desaturase (SCD) inhibitor.7 Figure…

Ferhan Abdullah Thursday, 09 November 2016 Experiment 7 The Separation of Three Organic Compounds by Acid-Base Reactions and Liquid-Liquid Extractions Abstract: The purpose of the experiment was to isolate the three mixtures 9-fluorenone , benzoic acid and benzocaine by the liquid-liquid extraction method and the acid-base reaction technique. Using the acid-base reaction technique, the acid and base are neutralized, producing salt and water. By using the liquid-liquid extraction method, two…

skills such as chemistry, physics, and engineering to develop different and new processes for manufacturing chemicals on a large scale ("17-2041.00"). STEM fields are important to society in many ways, and I hope that I can make a contribution to the area…
