Advanced Placement Chemistry Introduction

Are we not dust and ash?  Be it star dust first formed within the cauldron of stars, how do we define matter?  The fundamental definition of what composes our physical world continues to change as our knowledge of science advances.  Originating with the idea of matter being comprised of indivisible particles, scientific advancement has progressed to elucidate atomic structure and organize the periodic table.  Chemistry has defined models of bonding to explain molecular structure and how chemical reactions proceed towards equilibrium.  Chemical kinetics can be used to define the rate determining step, just as Stoichiometry can be used to define the limiting reagent.  Thermodynamics allows us the ability to determine when a reaction will occur spontaneously or will require energy.  Overall, Chemistry serves as the foundation upon which we approach both inorganic and organic systems.  From Biochemical reactions to Electrochemistry, Chemistry has allowed unparalleled scientific advancement.  Chemistry represents the very substance of which the future will be constructed:  a golden age which will behold the development of new medicines, sources of energy, and materials to create a sustainable and environmentally-friendly future.  Join us as we embark on this scientific journey to enlightenment.
