A snoke stack with an effective height of 45 m emits SO2 at a rate of 8 kg hr -1. What is the contribution of this stack to ground-level SO2 concentrations at a school yard 950 m downwind, if wind speed is 1.5 m s-1 on a sunny winter day? Assuming unlimited mixing height, and the atmosphere stability is unstable?

CaO(s) reacts with SO2 (g) according to the following equation: CaO(s) + SO2 = CaSO3(s). A 8.85 g mixture containing CaO(s) is placed in a 3.0L container. The container is filled with SO2(g) to a pressure of 749 torr, at 20 C. After the reaction has gone to completion, the pressue inside the flask is 390 torr also at 20 C. What is the mass of CaSO3(s) produced? assume that only CaO(s) in the mixture reacts with SO2(g).
