Ammonium sulfate, a key synthetic nitrogen fertilizer, is manufactured by reacting ammonia gas with sulfuric acid according to the equation:
2NH3(g)+H2SO4(aq)→(NH4)2SO4(aq) 2\text{NH}_3(\text{g}) + \text{H}_2\text{SO}_4(\text{aq}) \rightarrow (\text{NH}_4)_2\text{SO}_4(\text{aq}) 2NH3(g)+H2SO4(aq)→(NH4)2SO4(aq)Explain, by referring to this chemical equation, how it demonstrates that the atom economy of this process is 100%100\%100%.
