Calculate the number of tons of CaCO3 needed to react completely with 2.70 tons of SO2
The equation of reaction in the presence of oxygen is given below:
CaCO3 + SO2 + ½O2---> CaSO4 + CO2
From the balanced equation,
64g of SO2 reacts with 100g of CaCO3
2.70tons of SO2 will react with 100g/64g x 2.70tons = 4.22tons of CaCO3
