Question

Aqueous solutions of magnesium chloride and silver nitrate are mixed to form solid silver chloride and aqueous magnesium nitrate.The balanced net ionic equation contains which of the following terms?

• A. ${Ag}_{\left(aq\right)}^{+}$
• B. ${Mg}_{\left(aq\right)}^{2+}$
• C. ${NO}_{3\left(aq\right)}^{-}$
• D. $2{NO}_{3\left(aq\right)}^{-}$
• E. $3Ag{Cl}_{\left(s\right)}$

Answer 1

Answer: (A)

${Ag}_{\left(aq\right)}^{+}$

The balanced chemical equation is
Aqueous solutions of magnesium chloride and silver nitrate are mixed to form solid silver chloride and aqueous magnesium nitrate.
The balanced molecular equation is
$MgC{l}_2\left(aq\right)+2AgN{O}_3\left(aq\right)\to 2AgCl\left(s\right)\downarrow +Mg\left(N{O}_3{)}_2\right(aq)$
The balanced complete ionic equation is
$M{g}^{2+}\left(aq\right)+2C{l}^{-}\left(aq\right)+2A{g}^{+}\left(aq\right)+2N{O}_3^{-}\left(aq\right)\to 2AgCl\left(s\right)\downarrow +M{g}^{2+}\left(aq\right)+2N{O}_3^{-}\left(aq\right)$
The balanced net ionic equation is
$C{l}^{-}\left(aq\right)+A{g}^{+}\left(aq\right)\to AgCl\left(s\right)\downarrow$
The balanced net ionic equation contains the terms $A{g}^{+}\left(aq\right)$, $C{l}^{-}\left(aq\right)$ and $AgCl\left(s\right)$
