Catalog Course Description

An introductory course in the fundamental principles of chemistry. Topics covered are those necessary for understanding chemical structure and reactivity, and for scientific calculations. There is an emphasis on laboratory work and communication skills. The course is designed for science and engineering majors, pre-medical students, and as a general education class. 54 lecture hours, 126 lab hours.

Course Objectives

  • Recognize and discuss precision and accuracy pertaining to data and calculations.
  • Convert measurable quantities such as mass and volume into chemical quantities (the mol).
  • Calculate percent composition of a compound or use percent composition to calculate a chemical formula.
  • Recognize specific types of reactions such as redox, acid-base and precipitation.
  • Properly balance chemical reactions.
  • Calculate experimental, theoretical and percent yields of reactions.
  • Calculate yields based on limiting reagents.
  • Understand simple behaviors of gases and correctly apply the ideal and empirical gas laws.
  • Do computations using concentrations of solutions such as dilution, molarity, and stoichiometry.
  • Recognize acids and bases, the strength of an acid, presence of buffers, and be able calculate pH of a solution in calculations.
  • Describe chemical equilibrium and Le Chatelier's principle.
  • Appreciate the significance of uncertainty and significant figures in data and calculations.
  • Use equilibrium expressions to calculate concentrations and predict which way a chemical reaction will go.
  • Create useful conversion factors from standard units, densities, percentages, and chemical relationships.
  • Use specific heats and enthalpies of phase changes to calculate thermodynamic results.
  • Draw and interpret heating/cooling curves from appropriate data.
  • Describe the structure of atoms.
  • Describe the electron configuration and Lewis structures of atoms and ions, and be able to describe trends such as size and ionization energy.
  • Draw Lewis structures of molecules and ions and use VSEPR to predict properties of those molecules.
  • Categorize compounds as ionic, covalent, organic or acids, and name them appropriately.

Examples of Required Writing Assignments

There is considerable writing out of homework. Much of the homework is computational, but some involves detailed explanation of concepts such as, for example, explaining ionization energy trends, or similarities and differences between static systems and systems in a state of dynamic equilibrium, or in articulating the development of chemical concepts such as the evolution of the modern atomic model from the experiments of Thomson, Rutherford, Balmer, Bohr and others. Properly addressing these topics would typically require one or two well crafted paragraphs. Additionally, weekly lab reports of between 2 and 5 pages will often require time outside of class to produce work reasonably free of spelling and grammatical errors. As part of the lab reports, students are required to field post-laboratory questions that address mastery of the concepts and some analysis of the experimental results. Students are required to articulate interpretation of scientific data and results in a manner appropriate to their level of understanding.

Examples of Outside Assignments

Each student will have his/her own specific needs, but homework is selected to develop and assess mastery of foundational math and comfort level using "dimensional analysis" to solve a wide range of problems, to reinforce the memorization of nomenclature of chemical compounds and equations, and to help master specific chemical concepts such balancing reaction, calculating limiting reactants, etc.
