Zinc oxide reacts with dilute nitric acid to form zinc nitrate and water.
The equation for the reaction is:
ZnO(s)+2HNO3(aq)→Zn(NO3)2(aq)+H2O(l) \text{ZnO}(\text{s}) + 2\text{HNO}_3(\text{aq}) \rightarrow \text{Zn(NO}_3)_2(\text{aq}) + \text{H}_2\text{O}(\text{l}) ZnO(s)+2HNO3(aq)→Zn(NO3)2(aq)+H2O(l)Which row of the table shows the correct physical state of each of the substances in the equation for this reaction?
