The balanced equation for the hydrolysis of silicon ethoxide is Si(OCH2CH3)4 + 4H2O → Si(OH)4 + 4C2H5OH. In this reaction, silicon ethoxide reacts with water to form silica (SiO2) and ethanol (C2H5OH). Option B is the closest to this reaction, where Si(OCH2CH3)4 reacts with water (H2O) to form Si(OH)4 and ethanol (C2H5OH). The other options involve different reactants and products that are not part of the hydrolysis of silicon ethoxide.
