你中奖了。感觉很不容易考啊，下面的从网上找的 Study Guide for the American Chemical Society Standardized Final Exam for First Semester of General Chemistry CHM 115 Dr. Tremain This comprehensive exam consists of 70 multiple-choice questions. It is a two -hour exam scheduled for Wednesday December 18th from 8:00 am to 10:00 am. Arrive about 10 minutes early. Bring 2-3 #2 pencils, an eraser, and a calculator. Scratch paper and Scantron sheets will be provided. If you see any question on the exam that we have not covered in class (or you don’t remember right away how to answer it), skip that question and go on to the next one. Come back to those questions only after you have answered all the others. There is no penalty for guessing. Good luck on all your other finals as well ! Chapter 1 Definition of Chemistry States of matter Matter: Elements, Compounds, Mixtures (Homogeneous and Heterogeneous) Examples *Intensive and Extensive properties (see Chapter 11 Lecture Notes) SI Prefixes Conversion: kg to pounds, Temperature Difference between accuracy and precision Chapter 2 Postulates of Dalton’s Atomic Theory J.J. Thompson’s Cathode Ray Tube experiment (know the experiment and result) Millikan’s Oil Drop experiment (know the experiment and result) Rutherford’s Gold foil experiment (know the experiment and result) Definition of isotopes and examples of three elements with isotopes Names and formulas of Inorganic (Ionic) compounds Names and formulas of Cations and Anions including Polyatomic Ions (Tables 2.4, 2.5, 2.6, 2.7, & 2.8). See my lecture notes. Names and formula of molecular compounds Writing and balancing chemical equations Chapter 3 Relationship between mole, molar mass, and Avagadro's number (Calculations) Calculations of empirical and molecular formula (percentage composition) Everything dealing with Stoichiometry (amounts of reactants and products) Determination of a limiting reagent in a reaction and using it properly in a calculation Calculation of percent yield in a reaction Chapter 4 Definition of an electrolyte Examples of compounds that are strong electrolytes, weak electrolytes or non-electrolytes Net Ionic Equations (know how to predict products of precipitation reactions and the solubility rules) Definition of an acid and examples of mono-, di- and tri-protic acids Definition of a base Example of a neutralization reaction Oxidation-Reduction reactions (OIL RIG or LEO goes GER). Know oxidizing agent and reducing agent Balancing Oxidation-Reduction reactions Calculation of molarity and using molarity to find yield of a product in a reaction Definition and an example each for combustion, decomposition, combination reactions Chapter 5 Conversion of Pressure units between atmosphere, torr, mmHg and Pascals Boyle’s Law, Charles’ Law and Avogadro’s Law and the Ideal gas equation Calculations based on Ideal gas equation Dalton’s Law of Partial pressures Kinetic Theory of Gases and molecular speed of a gas Why do real gases do not follow the Ideal gas equation? Nonideal behavior Chapter 6 Potential and Kinetic Energy System and Surrounding - Internal Energy (U) First Law of Thermodynamics (Law of Conservation of Energy) Endothermic and Exothermic Processes Enthalpy, Enthaplies of Reactions, State Functions, Path Functions Heat Capacity and Specific heat Constant-Pressure and Constant-Volume Calorimetery (what you did in Lab Expt. 14 in SWM) Hess’s Law and Standard Enthalpies of Formation Chapter 7 Definition of wavelength and frequency Electromagnetic radiation (spectrum) Calculations relating wavele ngth, frequency, and speed of light Calculations relating energy to frequency using Planck’s constant Calculation of wavelength and/or frequency for a transition of an electron (absorption or emission) Bohr’s Theory of the Hydrogen Atom Definition Heisenberg’s Uncertainty Principle and the de Broglie relation Quantum Numbers n, l, ml and ms; Pauli Exclusion Principle; and shapes of atomic orbitals Chapter 8 Determination of electron configuration (Aufbau Principle) of atoms and ions Break up Periodic Table in s, p, d and f block orbitals Paramagnetic and Diamagnetic substances Identifying metals, non- metals and metalloids in a Periodic Table of the Elements (know their properties) Names of different groups in a Periodic Table of the Elements Periodic Trends in effective nuclear charge, atomic radius, ionic radius, ionization energy, electron affinity, electronegativity Classification of metal oxides as basic and non- metal oxides as acidic oxides Chapter 9 Ionic and covalent bonding and Lewis electron-dot symbols Writing Lewis structures: Octet rule, expanded octets, resonance structures, formal charges Bond length, Bond strength, DH and bond energy Chapter 10 VSEPR and Molecular Geometry; Dipole Moment and Polarity Valence Bond theory, sigma and pi bonds, multiple bonds Molecular Orbital theory and bond orders Chapter 11 Gases, Liquids, and Solids; phase transitions, amount of heat required to convert ice into steam Vapor pressure, boiling point, and melting point Phase diagrams, critical temperature, critical pressure, triple point Surface tension and viscosity Intermolecular forces: van der Waals, dipole-dipole, ion-dipole, induced dipole, London (dispersion), hydrogen bonding Types of solids: molecular, metallic, ionic, covalent network and their properties Crystalline solids, crystal lattice, simple cubic, body-centered cubic, face-centered cubic Hexagonal close-packed structure, cubic close-packed structure, coordination number |
