what is the net ionic equation for the rxn?

This forum made possible through the generous support of SDN members, donors, and sponsors. Thank you.
How would you approach to write the net ionic equation of this rxn?

HCl (aq) + NaOH (aq) --> H2O (l) + NaCl (aq)


thanks!

Ask yourself: what stays the same and what changes?

H: aq --> liquid (changes)
Cl: aq --> aq (stays the same)
Na: aq --> aq (stays the same)
O: aq --> liquid (changes)

From this you can write a NIE. Take out Na and Cl. You are left with:

H (aq) + OH (aq) --> H2O(l)
