CHM 113 Lecture Notes - Lecture 1: Ernest Rutherford, Henri Becquerel, Robert Andrews Millikan
Document Summary
Organic: study of organic compounds (primarily carbon and hydrogen) Inorganic: study if inorganic compounds (substances not composed of primarily carbon and hydrogen) Biochemistry: study of chemical processes that occur in living things. Physical chemistry: application of physical principles and measurements to understand properties of matter. Analytical chemistry: separation, identification, and quantification of chemical components. Matter- anything that has a mass and occupies space. Pure substances- matter with a fixed composition and distinct properties, can"t be separated by normal physical or mechanical means (grinding, using fingers, filtering, magnets, distillation, etc. ) Element- a pure substance consisting of one type of atom, listed on the periodic table by atomic symbol. Compound- atoms of two or more elements bonded together. Mixtures- two or more pure substances intermingled, can usually be separated by physical/mechanical mechanisms. Heterogenous mixture- non-uniform composition, may contain multiple phases; ex: A change in appearance or phase (solid, gas or liquid), but not the composition.
