Explanation:
i just took the test , i hope this helps:)
The equation that has been the representation of the net ionic equation has been Upper H superscript plus, plus upper O upper H superscript minus right arrow upper H subscript 2 upper O. Thus, option A is correct.
The balanced chemical equation for the reaction has been:
[tex]\rm Mg(OH)_2\;+\;2\;HNO_3\rightarrow Mg(NO_3)_2\;+\;H_2O[/tex]
The net ionic equation has been given as the ionic form of the reactants and product that has been formed in the reaction. The ions same on the product and reactant side of the equation has been eliminated in the net ionic equation.
The net ionic equation for the given chemical reaction has been:
[tex]\rm Mg^2^+\;+\;OH^-\;+\;2\;H^+\;+\;2\;NO_3^-\;\rightarrow\;Mg^2^+\;+\;NO_3^-\;+\;2\;H_2O\\OH^-\;+\;2\;H^+\rightarrow\;2\;H_2O[/tex]
The equation that has been the representation of the net ionic equation has been Upper H superscript plus, plus upper O upper H superscript minus right arrow upper H subscript 2 upper O. Thus, option A is correct.
