The symbol (g) after a chemical formula indicates which phase?

Explanation:
In chemical notation, the phase of a substance is shown in parentheses after its formula. The symbols (s), (l), (g), and (aq) stand for solid, liquid, gas, and aqueous, respectively. The symbol (g) specifically indicates the substance is in the gaseous phase. It’s used to distinguish gases from solids, liquids, or substances dissolved in water, as in CO2(g) for carbon dioxide gas or H2O(g) for water vapor. Since the question asks which symbol after the formula indicates the phase, the correct choice is the symbol itself: (g). Writing “Gas” describes the phase, but the notation used after a formula is the symbol that communicates that state.
