False, where does the chlorine come from light anyway???????
Answer:
H^+(aq) + OH^-(aq) -------> H2O(l)
Explanation:
We must first write the molecular reaction equation as follows;
HNO3(aq) + NaOH(aq) ------>NaNO3(aq) + H2O(l)
The complete ionic equation is;
H^+(aq) + NO3^-(aq) + Na^+(aq) + OH^-(aq) -------> Na^+(aq) + NO3^-(aq) + H2O(l)
The net ionic equation therefore is;
H^+(aq) + OH^-(aq) -------> H2O(l)
