Please EXPLAIN youranswer.

Explanation / Answer

a) S2O32- --->S4O62-' Look at reactant: O is always -2 so S must be +2 Work: 2(S) + 3(-2) = -2            S =+2 Look at product: again, O is -2 so S in this case must be +2.5 Work: 4S+6(-2) = -2            S = 2.5 The final (2.5) is greater than the initial (2.0)...an oxidizingagent is required.
