Answer

Hey,

The oxidation number of S are as follows:

1. 4

2. -1

3. 4

4. -2

Hope this helps :)

#1

You should know that H is usually +1, O is -2, Cl is -1, and Na is +1

So 1: we have -2 from O and 2 times -1 from Cl giving an overall negative charge of -4. Since the compound is neutral, S must have a +4 charge.

Follow the same reasoning for 2-4 and you will have the answer (are you sure you didn't meant H2S for #2?).

#2
