(i) Name the salt and the base.
The salt is Zinc Hydroxide while the base is Ammonium Nitrate.
(ii) Describe the observations for the reaction.
They they react with each other, white precipitate will be formed.
(iii) Write a chemical equation for the reaction (include state symbols).
ZnNO3(aq) + 2NH4OH (aq) > Zn(OH)2 (s) + 2NH4NO3 (aq)
(iv) Write an ionic equation for the reaction.
Zn 2+ (aq) + OH- (aq) > Zn(OH)2 (s)

Discussion is incomplete. In the presence of excess NH3, Zn(OH)2 dissolves forming a tetra-amine complex. At low pH, there is the possible formation of a double salt.
There are actually a whole lot of details like that to take into consideration. That could be a great level to convey up. I offer the ideas above as general inspiration however clearly there are questions just like the one you deliver up the place crucial thing will likely be working in sincere good faith. I don?t know if best practices have emerged around issues like that, however I'm positive that your job is clearly recognized as a fair game.
