The SO2 produced in copper recovery reacts in air with oxygen and forms sulfur trioxide. This gas, in turn, reacts with water to form a sulfuric acid solution that falls as rain or snow. Write a balanced overall reaction. (Type your answer using the format H2O for H2O. Use the lowest possible coefficients.)
