Chemistry 121: Introduction to Inorganic Chemistry Fall 2008 Chem 121 is the first of a 2 quarter series covering the fundamental concepts of inorganic, organic, and biological chemistry and is intended primarily for students in various healthrelated programs. Previous chemistry is required, either high school chemistry or Chem 100. Chem 101 requires moderate proficiency with algebra; as such Math 95 or Math 98 is a prerequisite (but may be taken concurrently). Suggested English language skills are placement in English 101. Chem 121 will develop the central concepts of measurement and determination of physical properties; scientific and analytical methodology, the nature of atoms, molecules, and ions; bonding between atoms and molecules; mass relationships and stoichiometry; solubility and solution chemistry. Additionally, Chem 121 will focus on chemical reactivity in terms of equilibrium and kinetics. Acids, bases, and pH will be considered in some depth, and oxidation and reduction will also be developed. The course will be presented within a framework of practical relevance, and should provide a “chemical scaffold” on which to interpret physical phenomena, with examples geared towards the health science student.

I reserve the right to normalize the grades upward if the class average falls below a C+. However, the more likely occurrence will be the assigning of additional problems for extra credit 2 Exams will be a combination of multiple choice, short answer (generally mathematically based), and fill in the blank. Questions for the examinations will be taken from material covered in lecture (≥ 90%) and reading assignments (≤ 10%). 3 Non-extra credit Schedule of Examinations: Section I: Physical Properties of Substances, Atomic & Molecular Structure Wednesday, 10/15 Section II: Mass Relationships and Stoichiometry - Behavior of Gases - Monday, 11/03 Section III: Solution Chemistry, Reaction Rate & Equilibrium - Monday, 11/17 Section IV: Acids, Bases, Salts & Buffers; Nuclear Chemistry (Final Examination) – Wednesday, 12/10, 1:00 to 3:00 pm, Rm C202 Make-up Examinations Make-up exams will be considered only if you approach me before the scheduled exam with an exceptional, documentable excuse. Documentation is mandatory before a make-up examination will be provided. If you miss an exam and have not notified me beforehand you will receive a zero for that exam. Due to time constraints, make-up examinations will not be given for poor test performance. Excusal from Final In the event a student has only to pass the final to receive an A for the course, he or she is excused from taking the final examination. Since the total number of graded (non-extra credit) points in the course is 600, .92(600) = 552 points are required for an A. As a passing score for the final is 59, 493 points (552 – 59) accumulated prior to the final is required to have the examination waived. This corresponds to 98.6% of graded points (493/500) on all other work. All other work must be turned prior to the final to exercise this option. Behavior You are students who have elected to pursue careers in the health sciences. As such, little needs be said concerning behavior. You should be mindful of creating distractions, as they only impede your fellow students’ chances of success. Please note that questions are never considered a distraction, but must be limited to the topic at hand. As a courtesy to others, cell phones should be turned off, or switched to vibrate only in the event an emergency call is anticipated. Cheating will not be tolerated under any circumstances. My standing policy is to give a score of 0 for any exam a student is caught cheating on. As each exam is worth 20%, and the division of letter grades roughly corresponds to 10% of the total points available, cheating on an exam will cost you no less than 2 letter grades. Disabilities Students with disabilities who believe they may need academic adjustments, auxiliary aids or services to fully participate in course activities or meet course requirements are encouraged to register with the Access and Disability Services (ADS) office, room N-115 in the Sunrise building. You may also call the ADS office to make an appointment to meet with the ADS coordinator at (253) 964-6568, (253) 964-6526, or (253) 964-6527. Students requesting accommodations must obtaint an Approved Academic Adjustments, Auxilary Aids or Services form from ADS.
