a) SO3 and SO2 do not represent a possible conjugate acid-base pair
b) CO3 and CO does not represent a possible conjugate acid-base pair
c) H3O and H2 if it was meant to be H30+ and H20 yes it does represent a possible conjugate acid-base pair
d) NH4+ and NH3 does represent a possible conjugate acid-base pair

HCl conjugate base is H2O (strong acid) HNO3 conjugate base is H2O (strong acid) CH3COOH conjugate base is CH3COO- H2CO3 conjugate base is HCO3- Think of it as these elements reacting with water, and donating protons if it's an acid, and accepting protons if it's a base. Strong acids dissociate completely, so their conjugate base is water. Ex. H2CO3 (aq) + H2O (l) ---> HCO3- (aq) + H3O+ (aq)
