How would you balance the following chemical equation: $H {g (N O_{3})}_{2} + K I \to H g I_{2} + K N O_{3}$ $Hg(NO_3)_2 + KI -> HgI_2 + KNO_3$ ?

Balance mass and balance charge.....

$H {g (N O_{3})}_{2} (a q) + 2 K I (a q) \to H g I_{2} (s) ⏐ ↓ + 2 K N O_{3} (a q)$ $Hg(NO_3)_2(aq) + 2KI(aq) rarr HgI_2(s)darr+2KNO_3(aq)$

And the net ionic equation is....

$Hg^(2+) + 2I^(-) rarrunderbrace(HgI_2(s)darr)_"orange solid"$

How would you balance the following chemical equation: Hg(NO_3)_2 + KI -> HgI_2 + KNO_3Hg(NO3)2+KI→HgI2+KNO3Hg(NO_3)_2 + KI -> HgI_2 + KNO_3?
