Answer:

Net ionic: $Mg(OH)_{2}+2NH_{4}^{+}\rightarrow Mg^{2+}+2NH_{3}+2H_{2}O$

Explanation:

$OH^{-}$ in $Mg(OH)_{2}$ reacts with $NH_{4}^{+}$ to form $NH_{3}$ and $H_{2}O$ .

Due to this acid-base reaction, $Mg(OH)_{2}$ become soluble whenever $NH_{4}NO_{3}$ is added to suspension of $Mg(OH)_{2}$ .

In this reaction, $NH_{4}NO_{3}$ acts as an acid and $Mg(OH)_{2}$ acts as a base.

Molecular equation: $Mg(OH)_{2}+2NH_{4}NO_{3}\rightarrow Mg(NO_{3})_{2}+2NH_{3}+2H_{2}O$

Total ionic: $Mg(OH)_{2}+2NH_{4}^{+}+2NO_{3}^{-}\rightarrow Mg^{2+}+2NO_{3}^{-}+2NH_{3}+2H_{2}O$

Net ionic: $Mg(OH)_{2}+2NH_{4}^{+}\rightarrow Mg^{2+}+2NH_{3}+2H_{2}O$

Battery or electrochemical cell

Explanation:

A battery is a power source that directs electrons from oxidation - reduction reactions to flow through a device to give electrical power.

A battery is an electrochemical cell.
Electrochemical cells are devices in which chemical reactions produce an electric current that is, chemical energy is turned into electrical energy.
The reactions here are spontaneous redox reactions, hence electrons flows on its own in an external circuit.
