Chlorine is used by textile manufacturers to bleach cloth. excess chlorine is destroyed by its reaction with sodium thiosulfate, na2s2o3, as follows:
na2s2o3(aq) + 4cl2( g) + 5h2o right-arrow 2nahso4(aq) + 8hcl(aq)
1)how many moles of hcl can form from 0.21 mol of cl2?
2)how many moles of h2o are required for the reaction of 0.18 mol of cl2?
3)how many moles of h2o react if 0.50 mol hcl is formed?
