Question

Complete the following reaction

$\mathrm{Zn}{\left(\mathrm{OH}\right)}_2+{\left({\mathrm{NH}}_4\right)}_2{\mathrm{SO}}_4+{\mathrm{NH}}_4\mathrm{OH}\to ............+{\mathrm{H}}_2\mathrm{O}$

Answer 1

Part-1 Balance reaction

• A balance reaction is a reaction where the number of atoms on the reactant side is equal to the number of atoms on the product side.
• That means the no. of atoms will remain constant during the whole reaction.

Part-2 Balanced chemical reaction of the following

$$\begin{gathered} \mathrm{Zn}{\left(\mathrm{OH}\right)}_2\left(\mathrm{aq}\right)+{\left({\mathrm{NH}}_4\right)}_2{\mathrm{SO}}_4\left(\mathrm{aq}\right)+2{\mathrm{NH}}_4\mathrm{OH}\left(\mathrm{aq}\right)\to \left(\mathrm{Zn}{\left({\mathrm{NH}}_3\right)}_4\right){\mathrm{SO}}_4\left(\mathrm{s}\right)+4{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right) \\ (\mathrm{Zinc}\mathrm{hydroxide})(\mathrm{Ammonium}\mathrm{sulphate})(\mathrm{Ammonium}\mathrm{hydroxide})(\mathrm{Tetraamine}\mathrm{zinc}(\mathrm{II})\mathrm{sulphate})\mathrm{Water} \end{gathered}$$
