Which chemical equation correctly represents the synthesis of calcium sulfite from calcium oxide and sulfur dioxide? CaSO3(s) → CaO(s) + SO2(g)
CaSO3(s) + O2(g) → CaO(s) + SO2(g)
CaO(s) + SO2(g) → CaSO3(s)
CaO(s) + SO2(g) → CaSO3(s) + O2(g)

)in the deacon process for the manufacture of chlorine, hcl and o2 react to form cl2 and h2o. sufficient air (21 mole% o2, 79% n2) is fed to provide 35% excess oxygen, and the fractional conversion of hcl is 85%. calculate the mole fractions of the product stream components.
