I 2 + S 2 O 3 2- ----- 2I - + S 4 O 6 2- 12H+ + 2IO3 + 10 I - ------ 6I 2 + 6H 2 O I need to combine these two reactions that there is no I 2 in...

I2 + S2O32- -----> 2I- + S4O62-

12H+ + 2IO3 + 10 I- <------> 6I2 + 6H2O

I need to combine these two reactions that there is no I2 in the over all reaction.

Would I divide the second reaction by 2 and the multiply the top reaction by 3??
