Final answer:
The Lewis dot structures for S2O3 2-, S2O8 2-, and F3S-SF can be represented as [:S=O::S:O=:]2-, [:S::O:1-O::S:O:1-O::O:1-]2-, and [F-S-F] respectively.
Step-by-step explanation:
In the S2O32- ion, there are 2 sulfur atoms and 3 oxygen atoms. The Lewis dot structure can be represented as follows:
[:S=O::S:O=:]2-
In the S2O82- ion, there are 2 sulfur atoms and 8 oxygen atoms. The Lewis dot structure can be represented as follows:
[:S::O:1-O::S:O:1-O::O:1-]
In F3S-SF molecule, there is one sulfur atom and two fluorine atoms. The Lewis dot structure can be represented as follows:
[F-S-F]
