    The earliest knowledge of chemistry was in 3500 B.C in Egypt and Mesopotamia. Chemistry was concerned anything that was pottery, dyes or crafts that were developed but not considerable skills because no one truly understood its purpose. The basic idea of elements or compounds were first formulated by Greek philosopher during 500 to 300 B.C when people believed fire , water, earth, and air combined to form all living and non-living things. In the beginning of Christianity an ancient Egyptian and Greek

    Chemistry and technology are together and separate. Chemistry uses technology and technology uses chemistry. The history of chemistry and technology is long going back to the ancient times. Chemistry was used even by the oldest civilizations, like Egypt. It was really popular during the medieval times. Back then it was called Alchemy, which is turning metal into gold or even about the philosopher’s stone. As the years went by, Alchemy became a lost art and chemistry took it in place. Chemistry led

    My Love of Chemistry I am applying to the university to study chemistry because this is the subject that I enjoy most. As with science in general, I find it interesting, often fascinating, and I feel that I could gain much from studying it at university. Last year I spent a fortnight on work experience, and enjoyed both of my two placements. At Birmingham University School of Chemistry, I was able to use some techniques that were new to me at the time - such as GCMS, HPLC, and I.R. spectroscopy

  • Chemistry and Carbohydrates

    1070 Words  | 3 Pages

    The Chemistry of Carbohydrates The chemistry of carbohydrates most closely resembles that of alcohol, aldehyde, and ketone functional groups. As a result, the modern definition of a carbohydrate is that the compounds are polyhydroxy aldehydes or ketones. The chemistry of carbohydrates is complicated by the fact that there is a functional group (alcohol) on almost every carbon. In addition, the carbohydrate may exist in either a straight chain or a ring structure. Ring structures incorporate two additional
