Lecture
This lecture provides step-by-step solutions to a practice exam in advanced general chemistry, covering topics such as electron configurations, energy changes, ionization energy, unpaired electrons, molecular shapes, hybridization, redox reactions, equilibrium shifts, and solubility. The instructor explains concepts using examples and calculations, including determining correct answers, identifying limiting reactants, and calculating pH and concentrations in electrochemical cells. The lecture also discusses decomposition kinetics and activation energy in chemical reactions.
