Hey guys! I'm not really stuck on this problem, but I was wondering if someone could look it over to make sure that what I did makes sense. Thank you:

1) Balance this equation. What is the coefficient in front of I2?
IO− + I− --> I2 in acidic solution

Maybe answer:
Since there is only one product, I was wondering if I split it up correctly
4H++2IO-+2e- -->I2+2H2O
2I- -->I2+2e-
2I-+4H++2IO- -->2I2+2H2O
I then divided both sides by two to get:
I-+2H++IO- -->I2+H2O
So my answer would be 1.
