Chlorine is used by textile manufacturers to bleach cloth. Excess chlorine is destroyed by
its reaction with sodium thiosulfate, Na 2 S 2 O 3 :
Na 2 S 2 O 3(aq) + 4Cl 2(g) + 5H 2 O (aq) ïƒ 2NaHSO 4(aq) + 8HCl (aq)
1. How many grams of Na 2 S 2 O 3 are needed to react with 2.65 mol of H 2 O? (3
marks)
2. How many mol of HCl can form from 25.2 mol of Na 2 S 2 O 3 ? (2 marks)
3. How many Liters of Cl 2 are required to produce 15.7 moles of NaHSO 4 ? (2
marks)
4. How many molecules of HCl can form from 4.92 grams of H 2 O? (3 marks)
I also need the steps. Please and thank you!
