There are several. Most are non-metalic oxides.

Carbon dioxide:
CO2 + H2O --> H2CO3 (carbonic acid)

Sulfur trioxide
SO3 + H2O --> H2SO4 (sulfuric acid)

Sulfur diodixe
SO2 + H2O --> H2SO3 (sulfurous acid)

Nitrogen dioxide
3NO2 + H2O --> 2HNO3 (nitric acid) + NO

There are many others.

CO2 when mixed with water produces H2CO3, a mild acid.
