Write the equation of all possible reactions between the following substances

Write the equation of all possible reactions between the following substances: water, silver oxide, sulfur oxide (4), sodium hydroxide, nitric acid.

Possible reactions between the given substances.
1. Water reacts with oxides.
H2O + Ag2O = 2AgOH.
H2O + SO2 = H2SO3.
2. Silver oxide interacts with nitric acid.
Ag2O + 2HNO3 = 2AgNO3 + H2O.
3. Sulfur oxide with acid and alkali.
SO2 + 2HNO3 = 2NO2 + H2SO4.
SO2 + 2NaOH = Na2SO3 + H2O.
4. Sodium hydroxide and nitric acid.
NaOH + HNO3 = NaNO3 + H2O.
