5: Classification and Balancing of Chemical Reactions

  • Page ID
    • 5.1: Chemical Equations
      Chemical reactions are represented by chemical equations that list reactants and products. Proper chemical equations are balanced; the same number of each element’s atoms appears on each side of the equation.
    • 5.2: Balancing Chemical Equations
    • 5.3: Classes of Chemical Reactions
      There are several recognizable types of chemical reactions: combination, decomposition, and combustion reactions are examples.
    • 5.4: Precipitation Reactions and Solubility Guidelines
    • 5.5: Acids, Bases, and Neutralization Reactions
    • 5.6: Redox Reactions
      Chemical reactions in which electrons are transferred are called oxidation-reduction, or redox, reactions. Oxidation is the loss of electrons. Reduction is the gain of electrons. Oxidation and reduction always occur together, even though they can be written as separate chemical equations.
    • 5.7: Recognizing Redox Reactions
      Redox reactions are common in organic and biological chemistry, including the combustion of organic chemicals, respiration, and photosynthesis.
    • 5.8: Net Ionic Equations
      The net ionic equation is the chemical equation that shows only those elements, compounds, and ions that are directly involved in the chemical reaction. Notice that in writing the net ionic equation, the positively-charged silver cation was written first on the reactant side, followed by the negatively-charged chloride anion. This is somewhat customary because that is the order in which the ions must be written in the silver chloride product.
