Q1 Zinc nitrate reacts with aqueous ammonia (NH4OH) to form a salt and a base.
  (i) Name the salt and the base.
 (ii) Describe the observations for the reaction.
(iii) Write a chemical equation for the reaction (include state symbols).
(iv) Write an ionic equation for the reaction.
Answers 
I) the salt is ammonium nitrate and the base is zinc hydroxide
ii) white solution is form when they are mixed together.
iii)ZnNO3(aq) +NH4OH(aq)-->ZnOH(s)+NH4NO3(aq)
iv)Zn+(aq) + OH-(aq)-->ZnOH(s)
