Which of the following correctly matches a state symbol with the state of a substance?
Answer and explanation

In a chemical equation, (aq) means aqueous: the substance is dissolved in water, so option A is correct. The other state symbols have specific meanings: (s) denotes a solid, (l) denotes a liquid, and (g) denotes a gas. Therefore option B incorrectly calls a solid gaseous, option C reverses liquid and solid, and option D reverses gas and liquid.
