The following reaction occurs in aqueous acid solution: NO3– +I– →IO3– +NO2 In the balanced equation, using the smallest whole-number coefficients, what is the coefficient of NO3–?

Would I use half reactions to balance: Cl_2 --> Cl- + ClO_3- ?

So, after I did the half-reactions, I still only got a coefficient for NO_3- to be 1, yet in the answer key provided (this is a practice midterm question), it says the coefficient is 6....I'm confused as to how you are supposed to figure that out.
