in my opinion, at high temperatures and pressures the answer would be :- none, i.e all metal oxides can be reduced by hydrogen.

Why metallic oxides are basic and non metallic oxides are acidic?
Metallic oxides are basic because they dissociate to form the hydroxyl ions while the non-metallic oxides are acidic because they dissociate to form hydrogen ions.
What metal oxides cannot be reduced to metal by hydrogen cuo ag2o fe2o3 mgo pbo?
cuo
What are metallic oxides?
metallic oxides are that type of oxides which contain metallic metals and oxides and which are cations like lithium, potassium e.t.c.
What is the difference between metallic and non metallic oxides?
Metallic oxides+ H2O - Base Non-metallic oxides+ H2O - Acid
Are non metal oxides acids or bases?
Metallic oxides are basic because they dissociate to form the hydroxyl ions while the non-metallic oxides are acidic because they dissociate to form hydrogen ions.

How can the classification of oxides be related to their metallic and non-metallic character?
The classification of oxides is related to their metallic and non-metallic character based on the type of elements they are composed of. Metallic oxides are formed by the combination of a metal with oxygen and are generally basic in nature. Non-metallic oxides, on the other hand, are formed by the combination of a non-metal with oxygen and are generally acidic or neutral. This classification is determined by the ionic or covalent nature of the bonding in the oxide compound.
Are non metal oxides acids or bases?
Metallic oxides are basic because they dissociate to form the hydroxyl ions while the non-metallic oxides are acidic because they dissociate to form hydrogen ions.
What is the relation between metallic iron and total iron in sponge iron?
If we talk about metallic iron in sponge, we mean content of reduced (pure) iron. Total iron content reflects Fe in any forms (reduced to pure Fe and Fe in oxides)
Are non metals oxide or bases?
Most of the non-metallic oxides are acidic in nature as CO2, SO3 and P2O5 but some non-metallic oxides are neutral as oxides of nitrogen.
Why are non metallic oxides acidic?
Apart from dinitrogen monoxide, nitrogen oxide and carbon monoxide, every non metallic oxides are acidic in nature.
What is formed when water is mixed with metallic oxide?
With some oxides metallic hydroxides are formed.
What does the nature of non metallic oxides?
Non-metallic oxides are acidic. Some are gases and readily dissolve in water. Others react with bases, such as silica, SiO2 and B2O3
Can hydrogen peroxide oxides hydrogen sulphide?
yes to hydrogen sulphate
