Summary

• Description:

  The PDF document comprises Form 1 Air and Combustion Notes.

  The topics and sub-topics covered in the document are listed below:

  • Composition of Air
    • Distinguishing if air is a mixture or a compound.
    • Approximate percentage composition of air.
  • Experiments to Determine the Percentage of Oxygen in Air
    • Using a burning candle.
    • By heating copper in a fixed volume of air.
    • Using the rusting of iron filings.
    • Using smouldering phosphorus.
    • Determining the presence of Carbon (IV) oxide and water in air.
  • Fractional Distillation of Liquefied Air
    • The process of separating components of air.
  • Rusting
    • Conditions necessary for rusting to occur.
    • Methods of preventing rusting such as painting, oiling, galvanizing, and sacrificial protection.
  • Oxygen
    • Laboratory preparation of oxygen using hydrogen peroxide and manganese (IV) oxide.
    • Physical and chemical properties of oxygen.
  • Burning of Substances in Air
    • Burning of metals like sodium, calcium, magnesium, iron, and copper in air.
    • Products of burning metals in oxygen (oxides and nitrides).
    • Burning of non-metallic elements like sulphur, carbon, and phosphorus.
    • Changes in mass when substances burn in air.
  • Reactivity and Competition for Oxygen
    • The reactivity series of metals.
    • Competition for combined oxygen among different metals (Redox reactions).
  • Atmospheric Pollution
  • Uses of Oxygen
  • Review Exercises
    • A set of questions to test understanding of the topic.
    • Past KCSE questions on Air and Combustion.

  These notes on Air and Combustion are comprehensive, neat, and printable, featuring clear explanations, diagrams, and practical experiments. They are an excellent resource for Form 1 students aiming to master the fundamentals of chemistry and are equally suitable for teachers preparing lessons and for students undertaking KCSE revision.
