Key Topics to Revise

1

Gas Laws and Standard Conditions

  • Boyle's law: volume is inversely proportional to pressure when amount of gas and temperature are constant.
  • Charles' law: volume is directly proportional to temperature when amount of gas and pressure are constant.
  • Gay Lussac's pressure-temperature law: pressure is directly proportional to temperature when amount of gas and volume are constant.
2

Gay Lussac's Law and Avogadro's Law

  • Gay Lussac's law of combining volumes was given in 1808.
  • When gases react, their volumes combine in simple whole number ratios if measured under identical conditions of temperature and pressure.
  • Example: hydrogen and chlorine react in the ratio 1:1:2 to form hydrogen chloride.
3

Atomicity of Elementary Gases

  • Atomicity is the number of atoms present in one molecule of a substance.
  • He, Ne, Ar and Kr are monoatomic molecules.
  • H2, O2, N2, Cl2 and Br2 are diatomic molecules.
4

Relative Atomic Mass, Average Atomic Mass and Mass of Atoms

  • Relative atomic mass compares the mass of an atom with a standard atom.
  • One atomic mass unit is 1/12 of the mass of an atom of C12.
  • In 1961, C12 was adopted as the standard for atomic mass unit scale.
