The balanced chemical equation is:

2 Zn + 2 HNO

As ions, this is:

2 Zn

There are no spectator ions, so the equation as written stands as the net ionic equation.

2 Zn + 2 HNO

_{3}---> 2 ZnNO_{3 }(s) + H_{2 }(g)As ions, this is:

2 Zn

^{2+}+ 2 H^{1+}+ 2 (NO_{3})^{1-}---> 2 ZnNO_{3 }(solid) + H_{2 }(gas)There are no spectator ions, so the equation as written stands as the net ionic equation.
