BaS = Barium Sulfide (leave it as is, it in emoerical form already)
CuSO4 = Copper(II) sulfate = CuSO4 5H2O
Fe2O3 = Iron(III) oxide (leave it as is, it in emoerical form already)

KC2H3O2 = Potassium Acetate (leave it as is, it in emoerical form already)
Al(OH)3 = Aluminium hydroxide (leave it as is, it in emoerical form already)
Fe(NO3)3 = Iron(III) nitrate (leave it as is, it in emoerical form already)
N2O5 = Dinitrogen pentoxide = N2O5 (it's subscrip is already simplified)
PO5 = Phosphorus pentoxide = P2 O5 (there was just no 2 after the P so that's all that was needed there)
I'm am so sorry if this didn't help too much, I hope I did help, I in some way, have a wonderful day.
