For 2019-2020 Year, Chapter 4 in Zumdahl. Objectives almost line-up exactly how Zumdahl presents the topics. 
 
*Topic 4.1 Introduction for Reactions 
**Identify evidence of chemical and physical changes in matter (Four Observation of Chemical Reaction). Also rearrangement of atoms after collision (makes chemical reaction).

*Topic 4.2 Net Ionic Equations 
**Besides balanced complete chemical reactions, complete ionic reaction (includes spectator ions), and net ionic reactions (without spectator ions) can represent a chemical reaction.
 
*Topic 4.3 Representations of Reactions 
**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.
 
*Topic 4.4 Physical and Chemical Changes 
**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.
 
*Topic 4.5 Stoichiometry 
**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.
 
*Topic 4.6 Introduction to Titration 
**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.
 
*Topic 4.7 Types of Chemical Reactions 
 
*Topic 4.8 Introduction to Acid - Base Reactions 
 
*Topic 4.9 Oxidation - Reduction (Redox) Reaction
