I would imagine it has a tetrahedral geometry since the Cl atoms are quite large in size, thus electron replusion is high, so adopts a geometry that gives the largest angle between the C-Cl bonds.
No, it does not. It contains all single bonds.
Yes
isomer
there are three resonating structures of H2CO3 OH+-------C------O+-------oh+

they don't.
three
It has resonance structures but no isomers.
NO
The sulfate ion has four resonance structures.
Usually two way arrows are placed between a molecule's resonance structures to indicate resonance
