Understanding chemical nomenclature and formulas is essential for science literacy. This knowledge enables the identification of compounds like H2O and CCl4, writing balanced equations, and understanding stoichiometry. The text explains the types of chemical formulas, such as molecular, empirical, and structural, and provides guidelines for writing them correctly. It also illustrates the process of constructing chemical formulas and their practical applications in identifying substances.
