what are the standard enthalpy of formation and standard molecular entropy for the following?

Question

I'm not even sure if some of these elements exist, but my chemistry teacher offered extra credit if we could find these. If you don't know, but you know the names of these, that would be appreciated too.

MnO3
Ba(OH2) - H2O (hydrate) - do these have the detla H and delta S with or without a hydrate?
NH4OH
Ba(NO3)2

There's no data required, because these are simply values you can find on a table.

Answer 1

Data required............
