some metal oxides were heated with non-metals , explain each of the following results
lead oxide +carbon=lead oxide+carbondioxide
lead oxide+hydrogen=no reaction
carbon oxide +hydrogen=copper+hydro oxide(water)

Your question is hard to follow, but I think that I understand.
Lead (II) oxide + Carbon ---> Lead + Carbon dioxide
2 PbO (s) + C (s) ---> 2 Pb (s) + CO2 (g)
The Carbon is more reactive than the Lead and will replace it.
Lead (II) oxide + Hydrogen ---> no reaction
The Hydrogen is not more reactive and will not replace it.
Copper (II) oxide + Hydrogen ---> Copper + Water (Hydrogen oxide)
CuO (s) + H2 (g) ---> Cu (s) + H2O (g)
The Hydrogen is more reactive than the Copper and will replace it.

I have answer only some parts of your question:
Carbon's position in the Reactivity Series:
Pottassium, Sodium, Magnesium, Aluminium, Carbon, Zinc, Iron, Tin, Lead.
Zinc, Iron, Tin, Lead can be extracted with carbon.
Carbon is more reactive than lead, thus this reaction can happen.
lead oxide + carbon = lead + carbon dioxide .
