a. Cu2+(aq) + 2OH-(aq) -----> CuO(s) + H2O(l)
b. 2CuOH(s) ------> 2CuO(s) + H2O(l)
c. Cu(OH)2(s) ------>CuO(s) + H2O(l)
d. Cu(OH)2(aq) ------> CuO(s) + H2O(l)
e. Cu(OH)2(aq) ------>Cu(OH)2(s)

Copper hydroxide is pretty insoluble.
The best equation is Cu(OH)2(s) ----> CuO(s) + H2O(l).
The solid changes from blue to black.
