Lessons in This Term
Gaseous State of Matter
The gaseous state is governed by kinetic molecular theory, ideal gas laws (Boyle's, Charles's, Avogadro's, Dalton's), and deviations seen in real gases under extreme temperature and pressure.
Energetics
Chemical energetics studies enthalpy changes (ΔH), Hess's law cycles, lattice energy (Born-Haber cycles), entropy (ΔS), and Gibbs free energy (ΔG) determining reaction spontaneity.
Chemistry of s, p, and d Block Elements
The periodic properties and chemical reactivity of s, p, and d block elements correlate directly with their valence electron configurations, oxidation states, and coordination chemistry.
