I'm guessing S3P4 + 7O2 --> 3SO2 + 4PO2

SO2 + H2O --> H2SO3 (=sulphurous acid)

aaagh not sure about phosphorus one, it's late and I'm a bit drunk :s Will remember it tomorrow!!

Ammonia is used to make the tollen's reagent which can be used to distinguish between aldehydes and ketones.

Also, its used for testing the solubilites of halides to distinguish between them..
