Balance each redox reaction occurring in acidic aqueous solution. Use the half-reaction method. Part A IO3−(aq)+SO2(g)→I2(s)+SO42−(aq)IO3− (aq)+SO2(g)→I2(s)+SO42−(aq) Express your answer as a chemical equation. Identify all of the phases in your answer. nothing SubmitRequest Answer Part B Sn4+(aq)+H2(g)→Sn2+(aq)+H+(aq)

A.

B.

Explanation:

Hello,

A.) In this case, the reaction with each oxidation state is:

Thus, the half reactions turn out:

And the result:

Simplifying:

B.) In this case, the half reactions are:

And the result:

Best regards.
