The pKa of ammonia is higher than that of water - NH3 is more basic, so that is more readily accepts a proton from the acid (consequently, the pKa of the acid is lowered in ammonia as the equilibrium is shifted towards the ethanoate anion) and, hence, it is stronger.

i dont no why cl does not react with o2. but chlorine(V)oxide forms by the reaction of hot conc. NaOH and Cl2
3Cl2 + 6NaOH= NaClO3 +3H2O+5NaCl
