Using the following equation 2c2h6 + 7o2 --> 4co2 + 6h2o if 2.5g c2h6 react with 170g o2, what is the limiting reactant?

)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.
