Which state symbol is used to represent a solid substance in a chemical equation?
Answer and explanation
Correct answer: (s)
In a chemical equation, the physical state of a substance is written in brackets after its chemical formula. The symbol \((s)\) represents the solid state; for example, \(\mathrm{NaCl(s)}\). Therefore, option A is correct. The symbol \((g)\) represents a gas, \((l)\) represents a liquid, and \((aq)\) represents a substance dissolved in water. State symbols make the actual physical conditions of reactants and products clear.
