The four state symbols show the physical state of substances at normal conditions. Symbol equations should be included when writing chemical equations. An example of a reaction with state symbols is the reaction of copper carbonate with hydrochloric acid: CuCO3 (s) + 2HCl (aq) CuCl2 (aq) + CO2 (g) + H2O (l)
Nov 21, 2017 · So its state symbol will be $\text{(aq)}$. Hydrogen on the other hand is a gas (at room temperature and above) and highly insoluble in water: it will leave the reaction as gas and its state symbol will be $\text{(g)}$. So without knowing the physical/chemical properties of the reagents/reaction products, the state symbols cannot be determined.
