Academic Chemistry Mr. Gensits Class Notes 1/27/2016 Unit One Introduction to Chemistry Chemistry – the study of the composition of matter and the changes that matter undergoes Matter – anything that has mass and takes up space Branches of Chemistry Organic Chemistry The study of all chemicals containing carbon. Inorganic Chemistry The study of all chemicals that, in general, do not contain carbon. Biochemistry The study of the chemical processes that take place in organisms. Analytical Chemistry The area of study that focuses on the composition of matter. The study of the composition, structure, and properties of matter, especially on the atomic/molecular level. Physical Chemistry This branch figures out how and why a chemical system behaves as it does. Studies the mechanism, the rate, and the energy transfer that occurs when matter undergoes a change. Approaches to Chemistry Pure Chemistry The pursuit of chemical knowledge for its own sake. Applied Chemistry Research that is directed toward a practical goal or application. Why Study Chemistry? Chemistry Explains... 1. Cooking Chemistry explains the changes that occur in food as it cooks, the rotting process, how to preserve food, how your body metabolizes food, and the interaction of ingredients in the foods we eat. 2. Cleaning Chemistry can be used to determine what cleaner is best for a particular purpose. What cleaner should be used for dishes, in the laundry, on your body, or anyway else throughout your home. Chemistry explains how detergents, soaps, bleaches, and other cleaners act. 3. Medicine Chemistry describes the interaction of vitamins, supplements, and drugs with your body. New medical treatments and medicines are researched and developed using chemical principles and knowledge. 4. Environmental Issues How does a particular chemical adversely affect the environment? What can be done to clean up chemical waste? Can clean technologies be developed and by what process? Chemistry is at the heart of environmental problems and their solutions.
