Final answer:

The acidic oxides are carbon dioxide (CO2) and sulfur trioxide (SO3), while sodium oxide (Na2O) is not acidic but is basic.

Step-by-step explanation:

The oxides that are acidic are carbon dioxide (CO2) and sulfur trioxide (SO3). The oxide of sodium (Na2O) is not acidic but is actually basic.

To determine if an oxide is acidic or basic, we can look at its reaction with water. Acidic oxides react with water to form acids, while basic oxides react with water to form bases.

For example, carbon dioxide reacts with water to form carbonic acid (H2CO3):

CO2 + H2O → H2CO3

Sulfur trioxide reacts with water to form sulfuric acid (H2SO4):

SO3 + H2O → H2SO4
