  • 1.2

    Types Of Chemical Reactions

    This section introduces various types of chemical reactions, including combination, decomposition, displacement, and double displacement, along with oxidation and reduction processes.

    Learning Practice

  • 1.2.1

    Combination Reaction

    Combination reactions involve the formation of a single product from two or more reactants.

    Learning Practice

  • 1.2.2

    Decomposition Reaction

    Decomposition reactions involve the breakdown of a single reactant into two or more simpler products, often with the input of energy.

    Learning Practice

  • 1.2.3

    Displacement Reaction

    Displacement reactions occur when one element replaces another in a compound, demonstrating the reactivity of metals.

    Learning Practice

  • 1.2.4

    Double Displacement Reaction

    Double displacement reactions involve an exchange of ions between two reactants, leading to the formation of a precipitate or a new compound.

    Learning Practice

  • 1.2.5

    Oxidation And Reduction

    This section explores oxidation and reduction reactions, emphasizing the definitions and processes of oxidation (gain of oxygen) and reduction (loss of oxygen).

    Learning Practice

  • 1.3

    Effects Of Oxidation

    Oxidation processes in everyday life lead to significant changes in substances, such as rusting in metals and rancidity in food.

    Learning Practice

  • 1.3.1

    Corrosion

    Corrosion is the process where metals, notably iron, degrade due to environmental interactions, leading to the formation of rust or other compounds.

    Learning Practice

  • 1.3.2

    Rancidity

    Rancidity refers to the process in which fats and oils become spoiled due to oxidation, leading to changes in smell and taste.

    Learning Practice
