Answer:
1.
Explanation:
Hello,
In this case, for the given reaction we first assign the oxidation state for each species:
Whereas the half reactions are:
Next, we exchange the transferred electrons:
Afterwards, we add them to obtain:
By adding and subtracting common terms we obtain:
Finally, by removing the oxidation states we have:
Therefore, the smallest whole-number coefficient for Sn is 1.
