Ca(OH)2 + HNO3 --> Ca(NO3)2 + H2O

Write the balanced molecular equation

2Ca(OH)2 + HNO3 --> Ca(NO3)2 + 2H2O

Now, split soluble compounds into ions & cross out the spectator ions on both sides of the complete ionic equation.

2H+ + 2NO3- + Ca2+ +2OH- --> Ca2+ + 2NO3- +2H2O

Net ionic equation: 2H+ + 2OH- --> 2H2O

This will always be the net ionic equation for a strong acid – strong base reaction, and the pH of the resulting solutions will always be 7.

I think the balanced equation should be Ca(OH)2 + 2HNO3 ==> Ca(NO3)2 + 2H2O. The ionic and net ionic equations are correct, and so is the interpretation and final answer, but I think she copied the balanced equation incorrectly.
