Write a balanced equation for the reaction of copper (II) hydroxide with aqueous ammonia to produce tetraamminecopper dihydroxide. Can you help plz?

Your general chemical equation is

##Cu(OH)_2(s) + 4 NH_3(aq) -> [Cu(NH_3)_4] (OH)_2(aq)##

The ionic equation looks like this:

##Cu(OH)_2(s) + 4 NH_3(aq) -> [Cu(NH_3)_4]^(2+)(aq) + 2OH^(-)(aq)##

Copper (II) hydroxied in ammonia solution is also known as Schweizer's reagent, a chemical used to dissolve cellulose.

##[Cu(NH_3)_4]^(2+)## is the tetraamminecopper (II) ion, a complex ion which I believe is also called cuprammonium ion.

Here's a video on some home-made Schweizer's reagent:
