This is the process:

2NO + O2 = 2NO2

SO2 + NO2 = SO3 + NO (Notice NO is produced at the end, so it's "acting" like a catalyst)

B!!
magnesium choride
NaCl is totally ionic
AlCl3 is covalent, cuz when it dimerises, it's a gas which is covalent
and SiCl4 is totally covalent

I HOPE ITX CLEAR TO U..:)

BUT mg has a high charge density so it will have a high polarising power so it will attract the electron towards it self so it will hav covalent character !!! watta u say ??

B!
butan-2-ol can be in 2 types (on the 2nd or the 4th carbon lets say)
so it'll produce 3 alkenes upon dehydration
