Final answer:
Without the appropriate balanced chemical equation that shows the reaction of Na2S2O3 to form HCl, it is not possible to determine the exact number of moles of HCl formed from 25.2 moles of Na2S2O3.
Step-by-step explanation:
The question seeks to determine how many moles of HCl can form from 25.2 moles of Na2S2O3. To answer this question, a chemical equation involving Na2S2O3 and HCl must be provided, or the context in which HCl is produced from Na2S2O3 must be known which has not been given here. The chemical formulas listed (such as NaOH, O2, H2O, NH3, and others in varying chemical equations) do not directly relate to the initial question asked about Na2S2O3 and HCl. Therefore, without the appropriate balanced chemical reaction, it is not possible to definitively calculate the number of moles of HCl that can be formed from 25.2 moles of Na2S2O3.
