Answer #1

Molecular equation

2HNO₃(aq) + Mg(OH)₂(s) → 2H₂O(l) + Mg(NO₃)₂(aq)

ionic equation

we can write ionic equation with soluble strong electrolytes as ions and Mg(OH)₂ is insoluble, so it is written as a molecule as well.

2H⁺(aq) + 2NO₃⁻(aq) + Mg(OH)₂(s) → 2H₂O(l) + Mg²⁺(aq) + 2NO₃⁻(aq)

Net ionic equation

Let us cancel all soluble species that appear on either sides of the equation. Cancel the NO₃⁻ ions.

The net ionic equation is

2H⁺(aq) + Mg(OH)₂(s) → 2H₂O(l) + Mg²⁺(aq)
