chemistry question

Hi,
I have this question Write balanced chemical equations as well as word equations underneath, showing the reactions of all the oxides of P and S with sodium hydroxide (NaOH).

I have two for P and 2 for S ( SO2, SO3 and P4O10 AND P2O5) not sure if that is all the possible outcomes. Please can someone help.

Thank you

Phosphorus Oxides
Phosphorus pentoxide (P2O5)
Balanced equation: P2O5 + 6 NaOH==>2 Na3PO4 + 3 H2O
Word equation: Phosphorus pentoxide + Sodium hydroxide==>Sodium phosphate + Water
Tetraphosphorus decaoxide (P4O10)
Balanced equation: P4O10 + 12 NaOH==>4 Na3PO4 + 6 H2O
Word equation: Tetraphosphorus decaoxide + Sodium hydroxide==>Sodium phosphate + Water
Sulphur Oxides
Sulphur dioxide (SO2)
Balanced equation: SO2 + 2 NaOH==> Na2SO3 + H2O
Word equation: Sulphur dioxide + Sodium hydroxide==>Sodium sulphite + Water
Sulphur trioxide (SO3)
Balanced equation: SO3 + 2NaOH==>Na2SO4 + H2O
Word equation: Sulphur trioxide + Sodium hydroxide==>Sodium sulphate + Water
Ciao,

P2O5 doesn’t really exist - it dimerises to P4O10. P4O6 is also a well-characterised oxide of phosphorus that has seen use as a ligand in transition metal chemistry. I believe it reacts with NaOH to give Na2HPO3 and water

8NaOH + P4O6 —> 4Na2HPO3 + 2H2O

Strictly sulphur has more oxides than that (SO, S2O, S2O2), but I don’t think you need to worry about them
