Burning coal and oil in a power plant produces pollutants such as sulfur dioxide, SO2. The sulfur-containing compound can be removed from other waste gases, however, by the following reaction:
2 502(g) + 2 CaCO3(s) + O2(g) → 2 Caso (s) + 2 CO2(g)
[Molar masses: 64.07
100.1 32.00 136.2 44.01)
a) Name the compounds involved in the reaction.
b.)what mass of CaCO3 is required to remove 155 g of SO2
c.) what mass of CaSO4 is formed when 155 g SO2 is consumed completely

let we see that when we burn then the gas is vapour which is like co2 and many more like that then the gas which is vapour is

adding or remove a gaseous reactant or product changes the concentrations. if the concentration of reactant or product is increased, the system will shift away from the side in which concentration was increased (i.e. if the concentration of reactants is increased, the system will shift toward the products. if more products are added, the system will shift to form more reactants). conversely, if the concentration of reactant or product is decreased, the system will shift toward the side in which concentration was decreased (i.e. if reactants are removed, the system will shift to form more reactants. if the concentration of products is decreased, the equilibrium will shift toward the products).
