Compounds Display Constant Composition

Another indicator that can be used to distinguish compounds from mixtures is the proportions of elements.

Law of Constant Composition

The law of constant composition: All samples of a given compound have the same proportions of their constituent elements. Water will always have 1 oxygen for every 2 hydrogen atoms (H2O).

Chemical Formulas: How to Represent Compounds

Chemical formula

Chemical formula: Indicates the elements present in a compound and the relative number

Endothermic Reactions

An endothermic reaction absorbs energy.

  • Heat (kJ) is written on the reactant side.
  • Bonds are broken; no new bonds are formed.
  • On Table I, the heat of reaction is positive (+).
  • The surroundings feel colder because energy is absorbed.

Exothermic Reactions

An exothermic reaction releases energy.

  • Heat (kJ) is written on the product side.
  • Bonds are formed.
  • On Table I, the heat of reaction is negative (−).
  • The surroundings feel warmer because energy is released.

Electronegativity

  • Electronegativity

Volumetric Analysis (Titration)

Experiment: KMnO4 vs Mohr’s salt (Ferrous ammonium sulfate)

Indicator: Self-indicator (KMnO4)

End point: Colourless → Permanent light pink

Ionic equations:

  • Reduction: MnO4– + 8H+ + 5e– → Mn2+ + 4H2O
  • Oxidation: Fe2+ → Fe3+ + e–

Rapid Viva Questions

  1. Why add dilute H2SO4?
    • Provides an acidic medium and prevents KMnO4 from getting reduced to MnO2 (brown precipitate).
  2. Why not HCl?
    • HCl reduces KMnO4, producing Cl2 gas.
  3. Why not HNO3?
    • Strong oxidizer; interferes with the reaction.

How Nuclear Power Plants Generate Electricity

Nuclear power plants are facilities designed to generate electricity using the energy released in nuclear fission reactions. Their operation is based on the use of fissile materials such as uranium-235, plutonium-239, or in some cases special mixtures for advanced reactors. When a uranium nucleus is struck by a neutron, it splits into two lighter fragments and releases a large amount of energy in the form of heat, while also emitting neutrons that can
