As you answer suggests, the elements are hydrogen and oxygen.
Hydrogen oxide???? I think you mean 'Water'. , which is hydrogen oxide. (H2O).
Universally , hydrogen oxide is never referred to as such, but ALWAYS , water'.
The elements found in ferrous oxide are iron (Fe) and oxygen (O).
Nitric oxide (NO) has 2 elements: nitrogen (N) and oxygen (O).
Mercuric oxide is made up of the elements mercury and oxygen. It is also called mercury(II) oxide, and has the formula unit HgO.
Mercuric oxide is made of the elements mercury and oxygen.
Aluminium oxide has two elements: aluminium and oxygen.

nitrous oxide, or N2O contains two elements, Nitrogen and Oxygen

Mercuric oxide is made of the elements mercury and oxygen.
There are two elements, namely sodium and oxygen.
Nitrogen oxide is composed of the elements, nitrogen and oxygen.
We know that iron (Fe) and oxygen (O) make up iron oxide. (There is more than one oxide of iron, by the way.)
The elements in a molecule of nitrous oxide are nitrogenand oxygen.
The elements in the compound potassium oxide are potassium and oxygen.
