Grade 9 Chemistry

د.ك199

High school chemistry introduces students to more complicated topics such as stoichiometry, thermodynamics, virtual laboratory experiments, and more. This strong base of knowledge will prepare them for subjects such as physics and advanced biology in the near future.

Some other topics that should be covered in tenth grade chemistry include:

  • The difference between physical properties and chemical properties of matter.
  • The relationship between the number of neutrons in an atom of an element, its mass number, and its isotopes.
  • How hydrogen bonding and van der Waals forces affect the volatility, boiling points, and melting points of liquids and solids.
  • How kinetic-molecular theory explains the properties of plasmas.
  • Spontaneous and nonspontaneous reactions.
  • The Bronsted-Lowry definitions of acids and bases.
  • The role of nuclear fusion to the production of essentially all elements heavier than helium.
