No it is polar covalent

Lewis base.
No. CH2O is formaldehyde, which is not an acid.
Br- is a Lewis base.
Sf6 acts as an lewis acid............
Being amphoteric water can react both: Lewis acid and Lewis base.
I think it is acid, because there is a question that asks the acid site of SO3.

Neither, it's a salt.
Lewis acid is an electron acceptor / Lewis base is an electron donor. It is helpful to use this definition of acid and base in (1) organic chemistry (2) also when there are no Hydrogens present in the molecule. BF3 is a Lewis acid it seeks out and can accept electrons.
PMe3 is a Lewis base(elctron donor).

an acid accepts an electron pair from a base
An acid accepts an electron pair from a base.
Mg2+ is (theoretically speaking) a Lewis acid, but I don't know how strong.
