    • 5.1: Chemical Equations
      The processes that occur during a chemical change can be represented using a chemical equation. In a chemical equation, the chemical formulas for the substance or substances that undergo the chemical reaction (the reactants) and the formulas for the new substance or substances that are formed (the products) are both shown, and are linked by an arrow.
    • 5.2: Classifying Chemical Reactions
      The reactions we have examined in the previous sections can be classified into a few simple types. Organizing reactions in this way is useful because it will assist us in predicting the products of unknown reactions. There are many different classifications of chemical reactions, but here we will focus on the following types: synthesis, decomposition, single replacement and double replacement.
    • 5.3: Redox Reactions
      Reduction-oxidation, or redox, reactions alter the relative density of electrons around atoms. Oxidations numbers help us keep track of theses changes.
