What the processes to produce the bulk chemicals ammonia or sulphur hydroxide

for my chemistry homework

There is no compound known as sulphur hydroxide may be you meant sulphur trioxide.
Ammonia is commercially produced by reacting N2 with H2 in presence of Fe catalyst and Mo promoter at high pressure (around 200 atm.) and high temp. (450 C). The process is called Habers process.

Two processes:
The Haber-Bosch Process and
Contact Process

Help produce bulk chemicals

Look up (a) Haber-Bosch Process and (b) Contact Process.
