For 2019-2020 Year, Chapter 4 in Zumdahl. Objectives almost line-up exactly how Zumdahl presents the topics.<br> <br> *Topic 4.1 Introduction for Reactions <br> **Identify evidence of chemical and physical changes in matter (Four Observation of Chemical Reaction). Also rearrangement of atoms after collision (makes chemical reaction).<br> *Topic 4.2 Net Ionic Equations<br> **Besides balanced complete chemical reactions, complete ionic reaction (includes spectator ions), and net ionic reactions (without spectator ions) can represent a chemical reaction. <br> *Topic 4.3 Representations of Reactions<br> **A substance that changes its properties, or that changes into a different substance, can be represented by chemical equations. Balanced chemical equations in their various forms can be translated into symbolic particulate representations. <br> *Topic 4.4 Physical and Chemical Changes<br> **Explain the relationship between macroscopic characteristics and bond interactions for a) Chemical processes b) Physical processes. Processes that involve the breaking and/or formation of chemical bonds are typically classified as chemical processes. Processes that involve only changes in intermolecular interactions, such as phase changes, are typically classified as physical processes. <br> *Topic 4.5 Stoichiometry<br> **Be able to understand what coefficients of a balance chemical reaction mean (particle, mole &volume ratios) and be able to do stoichiometric calculations (including ones combined with the ideal gas law and calculations involving molarity to quantitatively study gases and solutions. <br> *Topic 4.6 Introduction to Titration<br> **Be able to calculate titration (volumetric analysis) of various system (i.e. acid-base, redox) including understanding equivalence point endpoint of indicator (or reflection in mV). Be able to use titration to standardize a solution, determine the molar mass of a substance and other volumetric analysis. <br> *Topic 4.7 Types of Chemical Reactions<br> <br> *Topic 4.8 Introduction to Acid - Base Reactions<br> <br> *Topic 4.9 Oxidation - Reduction (Redox) Reaction<br> <br>
