Question #73238
use the following: Chlorine is used to bleach cloth. Excess Chlorine is destroyed by its reaction with Sodium Thiosulfate (Na2S2O3) according to the unbalanced equation Na2S2O3 + Cl2 + H2O → NaHSO4 + HCl.
How many moles of H2O are required for the reaction of 0.24 moles of Cl2?
A. 0.10 mol H2O
B. 0.20 mol H2O
C. 0.30 mol H2O
D. 0.40 mol H2O
E. 0.50 mol H2O

Expert's answer
Balanced equation:
Na2S2O3 + 4 Cl2 + 5 H2O → 2 NaHSO4 + 8 HCl
So, the amount of water: 0.24 ∙ (5/4) = 0.30 mol
Answer:
C. 0.30 mol H2O
Na2S2O3 + 4 Cl2 + 5 H2O → 2 NaHSO4 + 8 HCl
So, the amount of water: 0.24 ∙ (5/4) = 0.30 mol
Answer:
C. 0.30 mol H2O
