What is structure of SO3 (in solid state) at room temperature?
In solid phase SO3 exist at room temperature and have two different structures i.e. alpha-SO3 chain structure and gama- (SO3)3 cyclic structure (a trimer) like ice structure.
S-S bond is presents in? (IIT)

How can determine presence of Oxylinkage present in a given oxygen acids?
Condition
of presence of Oxylinkage in oxyacids:
If the calculated /average oxidation state of central atom of Oxy acid/oxy anion ,Oxide having two or more central atom is found to be one of its common oxidation state , then Oxy linkage will be present.
For
example:
H6P4O13: calculated
oxidation state is = +5
Common oxidation state of "P" is = +3, +5
It means calculated oxidation state matches with one
of the common oxidation state so there are Oxy linkage present in H6P4O13.
Note:
this rule is not applicable for H2N2O2
Hyponitrous acid, H2S2O3
Thiosulphuric acid and H2S2O5
Disulphurous acid or Pyrosulphurous acid.
