AP Chemistry Syllabus 2014 Text used: Chemistry by Zumdahl and Zumdahl, 9th ed., Houghton Mifflin Company, 2000. ISBN: 1133611095. Course Overview AP Chemistry meets five times per week for 50 minutes. Prerequisites for this course include general level physical and biological sciences, 2nd year algebra, honors chemistry, as well, pre-calculus or higher math course taken concurrently. This is a second year chemistry course for motivated students who intend to pursue a career in science. The structure, properties, and behavior of matter are examined theoretically and in the laboratory. College level text and labs are used. This course poses intellectual and laboratory challenges to all students and is equivalent rigor of college level general chemistry and chemistry lab, and many college’s honors level chemistry courses. Course Goals and Philosophy Develop students’ ability to think critically to solve problems in science. Allow students to attain an in depth knowledge of chemical phenomena. To produce individuals who have mastered the use of various chemical equipment and techniques. To gain the ability to make relevant observations and to analyze collected data qualitatively and quantitatively. Effectively communicate results of various investigations verbally as well as in a formal written report. To compile evidence of knowledge gain through experimentation and problem solving. Course Grading Policy Tests are given at the end of each unit. Quizzes and other formative assessments are given during the units. Labs are assessed mainly through lab reports while part of the grade depends on technique and obtaining expected result. Select homework problems are checked and graded for correctness. Student’s grade is based on the following weighted categories: Assessments (tests, quizzes) 80% Labs & Projects 15% Lab Points 5% Additional Help Material in this class is covered at a fast pace. Do not wait for help to be given; be proactive in asking questions and seeking additional assistance. I am available daily before school and during 4th and 6th periods on select days. Email, twitter, and the AP Chemistry YouTube channel offer even more support. matthewkirk@solonboe.org www.twitter.com/KirkChemistry www.youtube.com/KirkChemistry Schedule & Summary of Course Topics: Unit 1: Foundations of Chemistry (3 days) Observations Uncertainty in measurements Basic calculations and significant figures (conversions, temperature, density, etc.) Unit 2: Atom (5 days) Atomic theory (from early ideas to new) Chemical Laws Modern atomic structure Isotopes and average atomic mass Basic organization of the periodic table Naming all compounds, including o Simple compounds o Binary ionic Type I Type II o Binary covalent (type III) o Polyatomic ions o Acids Unit 3: Stoichiometry (5 days) Mole, molar ratios, atomic masses, % composition Determining molecular formula of compounds Components of chemical equations Balancing reactions Stoichiometric relations Limiting reactants Unit 4: Chemical Reactions (6 days) Aqueous solution reactions Details on all types of chemical reactions, including special emphasis: o o o Acid base reactions Precipitation reactions Oxidation reduction reactions Balancing Redox reactions note: 5 days will be spent later in the course after student have a deeper understanding of chemical relations Unit 5: Gases (6 days) Gas laws and their originators Combined gas law Ideal gas law Gas stoichiometry Kinetic Molecular Theory Diffusion and Effusion Characteristics of real gases Unit 6: Intro to Thermochemistry (8 days) Nature of energy Enthalpy and Calorimetry Hess’s Law Standard Enthalpies of formation Unit 7: Quantum Mechanics and Periodicity (7 days) Electromagnetic Radiation and Atomic Spectrum Electron Configurations: Quantum Numbers, orbital shapes, and Aufbau Principle Pauli exclusion principle, electron spin, and Hund’s rule Valence electrons, core electrons, and shielding Discovery of periodic trends Modern Periodic Trends in atomic properties, including: o Ionization energies (successive) o Electron affinities o Electronegativity o Atomic radii o Ionic radii o Metallic properties o Densities Properties of families, including: o Alkali metals o Alkaline Earth metals o Transition metals and varying oxidation numbers o Lanthanide and actinide series o Metalloids o Nonmetals o Noble Gases Unit 8: Chemical Bonds (15 days) Types of Bonding Bond Polarity Lewis-dot Structures o Octet rule and its exceptions o Resonance o Formal Charge VSEPR Theory – Molecular Shapes Hybridization of orbitals in bonding Unit 9: States of Matter (6 days) Intermolecular Forces of liquids and solids, including: o Dipole-Dipole interactions Hydrogen bonding o London Dispersion forces Instantaneous dipoles polarizability Liquids and their properties, including: o Surface tension o Capillary action o Viscosity o Vapor pressure and its relation to temperature Enthalpy of vaporization o Phase changes and phase diagrams including allotropic states Heating curves Enthalpy of fusion Supercooling Molecular and Ionic Solids o Network solids o Crystal Structure o Lattice Energy Metallic bonding structure o Packing arrangements and determination of density o Alloys Interstitial Substitutional Unit 10: Properties of solutions (7 days) Solution formation energies Effects on solubility, including o Pressure effects o Temperature effects o Structural effects Colligative Properties o Vapor pressure of solutions and non-ideal solutions o Boiling point elevation o Freezing point depression o Osmotic pressure o Electrolyte solutions and van’t Hoff factor Colloids and their properties, including o Coagulation o Tyndall effect Unit 11: Kinetics (9 days) Reaction Rates Rate Law Integrated Rate Law o Order of reactions Zero order First order Half-life reactions Second order Multiple reactant integrated rate law Catalysts o Heterogeneous o Homogeneous Unit 12: Chemical Equilibrium (24 days) Equilibrium Expression and Reaction Quotient Le Chatelier’s Principle Gaseous Equilibrium Kc, Kp Acid-Base Equilibrium – Kw, Ka, Kb o Calculating pH o Polyprotic Acids o Properties of Salts o Properties of Oxides o Buffers o Titrations Solubility Equilibrium – Ksp o Qualitative Analysis o Common ion effect o Complex Ion formation and equilibrium Unit 13: Spontaneity, Entropy, and Free Energy (12 days) Spontaneous processes and entropy 2nd Law of Thermodynamics Effect of Temperature Free Energy and chemical reactions o Pressure effects o Temperature effects o Relation to K o Relation to work Unit 14: Electrochemistry (11 days) Cell Potential o Nernst Equation Standard Reduction Potential Corrosion Electrolysis Review Additional time before the AP Chemistry Exam is used for reviewing and assessing knowledge Post Exam Students develop, initiate, and present a research project in contemporary chemistry topics. AP Chemistry Labs This course stresses hands-on laboratory experiments with emphasis on lab safety. At the end of lessons prior to labs, preparatory instructions and special techniques are explained in detail to the students. This becomes one of the most important safety precautions, knowledge of intention in the laboratory. A pre-lab assignment is a requirement of each student to complete and understand before each lab is conducted. This is especially important for safety and also allows the students to foresee and predict potential errors. All of the experiments conducted in the laboratory require collaboration with other students (typically with a partner). Not only collaboration to complete the experimental procedure in the allotted time but to also to interpret and analyze data obtained. Following each experiment, a debrief session is conducted. This is typically conducted in larger groups or as an entire class to share results with others and to aid in interpreting the data properly. Additionally, each lab is required to have a formal write-up presenting materials, procedure, data/analysis, and conclusion. The students are required to neatly organize data and manipulate it using Microsoft Excel. Conclusions should reflect students’ understanding of their results verses expected results, as well as detailed insight and explanation of sources of error. Lab reports are graded and returned to students in sheet protectors. Major errors or misinterpretations on lab reports are to be corrected and resubmitted. Students are additionally required to compile the lab reports in a separate lab binder. This binder allows students to reflect on laboratory experiments conducted as well as serve as evidence of having conducted the experiments. These labs constitute an average of one class period per week. Labs that require more than one class period are completed by the students after school or before school on the next day. Some suggested labs for AP chemistry are performed in honors chemistry (prerequisite). Some of the following labs are from: Slowinski, Emit J., et al. Chemical Principles in the Laboratory. 5th ed.
