Sulfur dioxide is an atmospheric pollutant.
Sulfur dioxide pollution is reduced by reacting calcium oxide with sulfur dioxide to
produce calcium sulfite.
CaO + SO2 → CaSO3
7.00 g of calcium oxide reacts with an excess of sulfur dioxide.
Relative atomic masses (Ar): O = 16 S = 32 Ca = 40 Calculate the mass of calcium sulfite produced
