Understand that in chemical equations, symbols in parentheses after a chemical formula indicate the physical state of the substance.
Recall the common state symbols: (s) for solid, (l) for liquid, (g) for gas, and (aq) for aqueous solution (dissolved in water).
Identify that the question asks specifically for the symbol representing the gaseous state.
Recognize that the symbol for a gas is (g), which stands for 'gas'.
Confirm that (g) is the correct symbol to indicate a chemical is in the gaseous state in a chemical equation.
