    Study Notes

    Types of Chemical Reactions

    • There are five main types of chemical reactions: combination, decomposition, displacement, double displacement, and precipitation reactions.

    Combination Reaction

    • A combination reaction occurs when two or more reactants combine to form a single product.
    • The formula for a combination reaction is X + Y = XY.
    • Also known as a synthesis reaction.
    • Example: 2Na + Cl2 = 2NaCl.

    Decomposition Reaction

    • A decomposition reaction occurs when a single chemical breaks down into two or more smaller components.
    • The formula for a decomposition reaction is XY = X + Y.
    • The exact inverse of a combination reaction.
    • Example: CaO + CO2 = CaCO3.
    • A thermal decomposition reaction occurs when a chemical decomposes as a result of heating.

    Displacement Reaction

    • A displacement reaction occurs when a more reactive element removes a less reactive element from its aqueous salt solution.
    • The formula for a displacement reaction is X + YZ = XZ + Y.
    • Also known as a substitution reaction.
    • Example: Zn + CuSO4 = ZnSO4 + Cu.
