Answer 1

Hybridization is `sp^2`. See image below.

Explanation:

Answer 2

`sp^2`

Explanation:

The electron pairs arrangement around sulfur is trigonal planar with a bond angle of around `120^@`.

For sulfur to achieve this geometry the orbitals `s` and `p` will mix to form three new hybrid orbitals called `sp^2` leaving a non hybridized orbital `p` for the lone pairs on sulfur.

For the oxygen atoms, we should consider the hybrid form of `SO_2`:

In the hybrid form the electron pairs arrangement around oxygen is also trigonal planar with a bond angle of around `120^@`.

For oxygen to achieve this geometry the orbitals `s` and `p` will mix to form three new hybrid orbitals called `sp^2` leaving a non hybridized orbital `p` for one of the two lone pairs and the second will be in a `sp^2` hybrid orbital.
