Introductions with an overview of scientific methods, scientific notation, measurements, units and unit conversions, using proper significant figures to indicate precision, general concepts in matter and energy including definitions of atoms, elements, molecules, compounds, and moles, chemical formula stoichiometry, basic layout of the periodic table, examples of endothermic and exothermic reactions, and Coulomb’s law.
Week Two: More study of atomic structure including ions and isotopes, information on the organizations of the periodic table of elements including some periodic trends (orbital energy, ionization energy, electronegativity, and atomic radius), identification of the subatomic particles most critical to chemical reactions, and introduction to ionic bonding. Introduction to calculations involving heat capacity and density.
Week Three: Determination of oxidation states, comparison of ionic and covalent bonding concepts, nomenclature for both ionic and molecular compounds including those containing polyatomic ions, and introduction to calculations involving formula mass and/or density.
Week Four: Introduction to chemical composition calculations (compound stoichiometry); application of mole ratios and more practice with gram/mole and mass percent calculations; determination of empirical and molecular formulas; balancing chemical reaction equations.
Week Five: No new topics this week. Optional peer-reviewed writing assignment due for students interested in earning a statement of accomplishment with distinction.
Week Six: Practice writing and balancing chemical reaction equations for dissolution processes; reaction stoichiometry application exercises; introduction to equilibrium constants using the solubility product constant as an illustration; electrolytes.
Week Seven: Introduction to precipitation, acid-base, and redox reactions; more practice applying reaction stoichiometry concepts; reaction calculations including limiting reagent, yield, and enthalpy changes.
Week Eight: No new topics this week. Complete exam and course survey.
Coursera est une entreprise numérique proposant des formation en ligne ouverte à tous fondée par les professeurs d'informatique Andrew Ng et Daphne Koller de l'université Stanford, située à Mountain View, Californie.
Ce qui la différencie le plus des autres plateformes MOOC, c'est qu'elle travaille qu'avec les meilleures universités et organisations mondiales et diffuse leurs contenus sur le web.
