Review Guide for Chemistry Final with Mrs. Fringer Date of Chemistry Final: Tuesday, June 10th The following are the chapters that have been covered in your chemistry class. For each chapter there are key concepts below that will be focused upon. In addition, each student should complete the questions provided within each chapter. Students are encouraged to bring any questions they have about the midterm to class. These questions will be addressed at the beginning of the class period. Chapter 2: Chapters 2.1 – 2.4 o Elements, compounds, mixtures (homogeneous and heterogeneous) o Physical and Chemical Changes o Physical and Chemical Properties o Separating mixtures Chapter 3: o o o Dimensional Analysis Significant Figures Density – be able to calculate density. You are responsible for knowing the formula. Chapter 4: Chapters 4.1-4.3 o History of the atom – know the scientists that helped to develop the concept of the atom o Be able to identify which scientists did which experiments when devising their theory of the atom. o Be able to identify which scientist developed with diagram of the atom. o Atomic number, mass number (atomic mass) o Be able to calculate the number of protons, electrons, and neutrons in an element. o Explain isotopes o Be able to calculate the mass number of an element based upon the element’s isotopes. Chapter 5: Chapters 5.1-5.3 o History of the atom – know the scientists that helped to develop the concept of the atom o Be able to identify which scientists did which experiments when devising their theory of the atom. o Be able to identify which scientist developed with diagram of the atom. o o o o Electron configuration Aufbau Principle Pauli Exclusion Principle Hund’s Rule o o o o o Radioactivity – Types of Radiation Nuclear Stability and Nuclear Reactions Half-life Nuclear power – fission Application of radiation Chapter 25: Chapter 6: Chapters 6.1-6.3 o Know the scientists that helped to develop the periodic table: Mendeleev o Explain Periodic law and give examples o Identify metals, nonmetals, and metalloids on the periodic table as well as their characteristics o Classify elements by groups o Know trends within the period table based upon charges of element, electron configuration, valance electrons, electronegativity, ionization energy, atomic radius Chapter 7: Chapter 7.1-7.3 o Know basic characteristics of ionic, covalent, and metallic bonds o Identify the valance electrons for each main group elements o Octet rule o Be able to give examples and cite cations and anions o Demonstrate an ionic bond and the transfer of electrons Chapter 8 – Covalent Bonding Chapter 8.1-8.4 o Know the characteristics of covalent bonds o How to draw covalent bonds o Identify the shapes of covalent bonds o Identify the polarity of a covalent molecule o Identify and explain the difference molecular forces Chapter 9 – Chemical Formulas Chapter 9.1-9.3 o Write the name and the formula for binary ionic, binary covalent, and polyatomic ions Chapter 10 – Chemical Quantities o o o o o Convert between mass, moles, volume, molecules and atoms Calculate percent composition Determine the empirical and molecular formulas Identify the molar mass or density of a gas Hydrates Chapter 11 – Chemical Reactions o o o o Balance chemical equations Identify word equations Identify the types of reactions Predict the products of combustion, double replacement, and single replacement reactions Chapter 12 – Stoichiometry o o o Law of conservation of mass Chemical calculations – mass to mass calculations and volume to volume calculations Limiting reagents
