Interpretation:
The oxidation states of sulfur in S8 should be determined.
Concept Introduction:
The oxidation state is defined as the charge(s) that an atom would have when electron(s) were transferred completely from a molecule or ion.
Interpretation:
The oxidation states of sulfur in H2 SO4 should be determined.
