    Study Notes

    Types of Chemical Reactions

    • Combination reaction: A + B → C
    • Decomposition reaction: C → A + B
    • Combustion reaction: Fuel + oxygen → carbon dioxide and water
      • Involves a fuel (often a hydrocarbon) reacting with oxygen
      • Produces carbon dioxide and water
    • Single Replacement reaction: AB + C → AC + B
    • Double Replacement reaction: AB + CD → AD + CB
    • Neutralization reaction: HA + MOH → MA + Hâ‚‚O

    Combustion Reaction

    • Example: CHâ‚„ + 2Oâ‚‚ → COâ‚‚ + 2Hâ‚‚O
    • Definition: A reaction in which a compound reacts with oxygen molecules
    • Typically involves fuels, which are often hydrocarbons
    • Produces carbon dioxide and water

    Decomposition Reaction

    • Definition: A reaction in which one compound breaks down into two or more compounds
    • Opposite of a synthesis reaction, where two or more reactants form one compound
