Quizplus · Accepted Answer

The reactants are COS (carbonyl sulfide) and O2 (oxygen), which undergo combustion to yield CO2 (carbon dioxide) and SO2 (sulfur dioxide). However, since there is excess oxygen present, some sulfur dioxide will further react with the oxygen to form sulfur trioxide (SO3), which then reacts with water to form sulfuric acid (H2SO4). The final products, therefore, are CO2, SO2, H2SO4, and water (H2O), which can be written as CO₂ and H₂O.
