The exam focuses on inorganic and physical chemistry, addressing atomic structure, ionization energies, and periodic trends. Key topics include titration calculations, mole ratio derivations, and enthalpy changes for acid-base and metal-acid reactions. Analytical techniques involve mass spectrometry, stoichiometry, and calculation of relative atomic masses. Practical chemistry includes improving experimental setups for accuracy and evaluating thermal changes in reactions. Reaction mechanisms emphasize redox equations, ion configurations, and energy levels in transitions. Molecular geometry is explored in bond angles, lone-pair influences, and co-ordinate bonding. Group properties analyze trends in melting points, solubility, and oxidation states, with quantitative skill integration.
