How do I complete this?

Question

A neutralization reaction takes place when aqueous barium hydroxide and aqueous nitric acid are mixed.

Write the molecular equation, the complete ionic equation, and the net ionic equation.

I am completely confused on how to balance in order to write each equation. Please assist in the steps.

Answer 1

Step 1 balance the molecular equation.

Ba(OH)2 + 2 HNO3 ======> Ba(NO3)2 + 2 H2O

Step 2 write the balanced equation showing all ions (complete ionic equation)

Ba 2+ + 2 OH- + 2 H+ + 2 NO3- ======> Ba2+ + 2 NO3- + 2 H2O

Step 3 cancel spectator ions on both sides (net ionic equation)

2 H+ + 2 OH- ========> 2 H2O
