Which state symbol represents a substance in the solid state in a chemical equation?
Answer and explanation
Correct answer: (s)
The state symbol (s) denotes that a substance is in the solid state. In the same notation, (l) means liquid, (g) means gas, and (aq) means the substance is dissolved in water as an aqueous solution. For example, CaCO3(s) shows solid calcium carbonate. These symbols describe physical state and do not by themselves indicate whether a chemical reaction has occurred. Therefore option A is correct.
