The exam explores inorganic and physical chemistry, including electron configurations, ion sizes, and first ionization energies. It covers titration-based molar mass determination, bond formation, and structure-function relationships in periodic elements. Practical applications involve bromine and magnesium phase changes, mass spectrometry for isotopic abundance, and redox reactions. Quantitative tasks assess stoichiometry, mole calculations, and experimental design in preparing solutions. Topics like molecular shapes, reaction energetics, equilibrium dynamics, and empirical formulas are integrated to test theoretical knowledge, problem-solving skills, and practical execution.
