Topics covered include properties of solutions, chemical equilibrium principles, acidbase equilibria, chemical kinetics and thermodynamics, electrochemistry, chemistry of coordination compounds, qualitative analysis, and an introduction to quantitative analytical chemistry. Other topics such as environmental chemistry, organic chemistry, materials, and others may be covered. COURSE OBJECTIVES Upon completion of this course, students must be able to: 1. Understand phases, change in phase, vapor pressure, phase diagrams, types of intermolecular forces and solid state properties and bonding; 2. Understand the origin of intermolecular forces in solutions and their influence on physical properties such as surface tension, boiling and melting points, viscosity, vapor pressure, heat of vaporization and critical temperature; 3. Write equilibrium constant relationships, determine whether equilibrium has been established and calculate equilibrium concentrations; 4. Use Le Châtelier’s Principle to predict the effects of concentration, pressure and temperature changes on equilibrium mixtures and chemical reactions; 5. Understand reaction rate and its dependence on concentration of reactants, physical state and reaction temperature, how reaction rates can be expressed mathematically, energy, how reaction mechanisms are determined; 6. Understand and perform calculations with the thermodynamic functions, enthalpy, entropy, free energy; describe how chemical equilibria depend on enthalpy, entropy and Gibbs Free energy; 7. Differentiate between galvanic and electrolytic electrochemical cells; determine standard and non-standard cell potentials; calculate equilibrium constants from cell potential data; 8. Describe the primary differences between inorganic (transition metal) and organic (carbon-based) chemical compounds; 9. Understand the relationship between chemistry, industry and society significant to the Philippine and international setting; 10. Develop an appreciation how chemistry supports the growth of science and technology; and 11. Appreciate how chemistry can contribute to the Ateneo mission of being “Men and Women for Others” COURSE OUTLINE Topic/Activity Introduction to the Course Review: Lewis Structure and Bonding Chapter 12 Intermolecular Forces: Liquids, Solids and Phase Changes Chapter 13 The Properties of Solutions Chapter 16 Chemical Kinetics: Rates and Mechanisms No Classes: November 16, 2012 (Friday) – Faculty Day November 30, 2012 (Wednesday) – Bonifacio Day EXAM 1 – December 19, 2012 December 22, 2012 to January 6, 2013 – Christmas Break Chapter 17 Equilibrium: Extent of Reactions Chapter 18 Acid-Base Equilibrium Chapter 19 Ionic Equilibria No Classes February 4, 2012 – President’s Day EXAM 2 – Last Week of January/First Week of February Chapter 20 Thermodynamics (Entropy, Free Energy, and Direction of Chemical Reactions) Chapter 21 Electrochemistry EXAM 3 – Second Week of March Final Exam – Week of March 19-24, 2012 * Subject to change depending on progress of the class. REQUIRED READINGS AND MATERIALS Textbook: Principles of General Chemistry, 2nd Edition by Martin Silberberg (McGraw-Hill). A calculator capable of arithmetic, powers, and exponential functions is essential for examinations, quizzes and problem sets. No programmable calculators, or cellular phone or PDA based calculators are permitted for use during quizzes or examinations. Some students will benefit by referring to other texts: Principles of General Chemistry by Petrucci, Harwood and Herring and Chemistry: The Central Science by Brown, Lemay and Bursten. HOW YOUR GRADE WILL BE DETERMINED 1. There are three (03) announced department-wide “pre-final” examinations @ 100 points per exam (3 exams X 100 points each = 300 points possible). 2. There are ten (10) announced pop quizzes @ 10 pts each. The combined marks in these activities is a 100 points, the same number of points as a pre-final examination (10 quizzes/homework X 10 points each = 100 points possible) 3. One (01) announced comprehensive final examination @ 200 pts taken during the final examination week. (1 exam X 200 points = 200 points possible) 4. The highest possible post-final score that a student can earn is 600 points. Requirement Three (3) Pre-Final Exam (100 points each) Comprehensive Finals Quizzes (10 quizzes) TOTAL Score 300 200 100 600 A student’s total accumulated points divided by 600 (the maximum points possible) will be translated to a letter grade as follows: % Final Grade >90.5 85.5-90.4 79.5-85.4 72.5-79.4 65.5-72.4 59.5-65.4 <59.4 Letter Grade A B+ B C+ C D F CLASSROOM POLICIES EXAMS AND QUIZZES: There will be 10 quizzes, four examinations. Unexcused absences from any quiz or exam will result in a grade of zero for that quiz/exam. Excused absences from an exam include: serious illness, death or serious illness in the immediate family. In all cases, it is the student’s responsibility to notify the instructor, or the Department of Chemistry Secretary (Phone: 426-6001 local – 5620), prior to the quiz/exam to be officially excused from the Exam. PROBLEM SOLVING CLASSES: An extra one-hour problem-solving period will be held each week. The date and time will depend on the class schedule of the students. The instructor and/or teaching assistants will handle these sessions and will serve as a venue to master analytical skills in Chemistry. ATTENDANCE. Attendance is required in all class lectures, problem solving sessions and examinations. Students may be allowed cuts up to a maximum of 9 absences for M-W-F classes and 6 for T-Th classes. Exceeding this limit will automatically result in withdrawal of the student from the class (a grade of W). While the class roll may not be called regularly, your attendance will be under continuous scrutiny. Do make it a habit to arrive on time. Absences and tardiness will prohibit you from turning in your homework, taking a quiz or an exam. DISCIPLINE. Students are expected to behave properly given the academic setting. As such, cellular phones, computers and other electronic gadgets are prohibited during lecture and exams. Students are also encouraged to finish assigned homework and problem sets outside of class as students may be called to solve problems in front of the class. The teacher reserves the right to remove anyone from the classroom on the grounds of discourtesy to the teacher or fellow student. HONESTY. In keeping with the Mission Statement of Ateneo, academic, professional, and personal honesty is imperative. Academic dishonesty of any kind will be penalized and immediately reported to the Departmental Chair. Your signature on exams and any other work submitted affirms that you understand the academic honesty requirement. The minimum penalty for dishonesty (e.g. cheating, plagiarism, etc) is a grade of zero for the particular test/quiz/ examination/problem set. Should there be evidence that a particular case is continuous or consistent, the maximum penalty allowed by the University will be pursued. OTHER CONCERNS. If a student has a disability that interferes with learning, please see the instructor on a confidential basis so that a strategy can be devised to overcome whatever barriers may exist. You are encouraged to do all the homework problems and then some. Please see your instructor during consultation hours or by appointment if at any point in the semester you feel that you are having problems with the work.
