Answer 1

SO3+2NaOH-------------->Na2SO4+H2O
SO2+2NaOH-------------->Na2SO3+H2O
SiO2+2NaOH-------------->Na2SiO3+H2O
N2O3+2NaOH------------>2NaNO2+H2O
N2O5+2NaOH-------------->2NaNO3+H2O
P2O3+6NaOH------------------>2Na3PO3+3H2O
P2O5+6NaOH------------->2Na3PO4+3H2O
Cl2O7+2NaOH-------------------->2NaClO4+H2O

Answer 2

SO₃+2NaOH  →  Na₂SO₄ + H₂O
SO₂ +2NaOH   →Na₂SO₃  + H₂O
SiO₂  + 2NaOH  →  Na₂SiO₃+ H₂O
N₂O₃ +  2NaOH  → 2NaNO₂  + H₂O
N₂O₅  + 2NaOH  →  2NaNO₃  + H₂O
P₂O₃  + 6NaOH →   2Na₃PO₃ + 3H₂O
P₂O₅   +6NaOH  →  2Na₃PO₄ + 3H₂O
Cl₂O₇  +2NaOH →  2NaClO₄ + H₂O
