1. Burning coal and oil in a power plant produces pollutants, such as sulfur dioxide, SO2. This compound can be removed by the following reaction:

2 SO2 (g) + 2 CaCO3 (s) + O2 (g) à 2 CaSO4 (s) + 2 CO2 (g)

a. How many grams of carbon dioxide are made from 155 g of SO2 ? This is the theoretical yield.

b. If the actual yield of carbon dioxide is 90.0 grams, what is the percent yield?
