a) CuO (s)+ H2SO4(aq) = CuSo4(aq) + H2O(l)
b) Cu+2 + SO4_2 = CU + SO4

so the ionic equation will be:
CuO+2H(1+)->Cu(2+)+H2O
is it correct?

balanced equation is
cuo(s)+H2SO4(aq)=cuso4(aq)+H2O(l)
thus ionic is
cuo+2H+=CU2++H2O

Most metal oxides are insoluble in water. (General)

Several common oxides are known to dissolve in water such as:

Sodium Oxide
Potassium Oxide
all other group I Metal Oxide
Barium Oxide

The above are the common ones.
