To determine which chemical equation correctly represents the reaction described, we need to consider the states of the reactants and products as given in the description.The description states that carbon dioxide gas reacts with liquid water to produce aqueous carbonic acid. This means we are looking for an equation where carbon dioxide is in the gaseous state (g), water is in the liquid state (l), and carbonic acid is in the aqueous state (aq).Let's analyze the options:a) \(\mathrm{CO}_{2}(\mathrm{g})+\mathrm{H}_{2}\mathrm{O}(\mathrm{g}) \rightarrow \mathrm{H}_{2}\mathrm{CO}_{3}(\mathrm{aq})\)This option incorrectly shows water as a gas (g).b) \(\mathrm{CO}_{2}(\mathrm{g})+\mathrm{H}_{2}\mathrm{O}(\mathrm{l}) \rightarrow \mathrm{H}_{2}\mathrm{CO}_{3}(\mathrm{aq})\)This option correctly shows carbon dioxide as a gas (g), water as a liquid (l), and carbonic acid as aqueous (aq).c) \(\mathrm{CO}_{2}(\mathrm{l})+\mathrm{H}_{2}\mathrm{O}(\mathrm{l}) \rightarrow \mathrm{H}_{2}\mathrm{CO}_{3}(\mathrm{l})\)This option incorrectly shows carbon dioxide as a liquid (l) and carbonic acid as a liquid (l).d) \(\mathrm{CO}_{2}(\mathrm{l})+\mathrm{H}_{2}\mathrm{O}(\mathrm{l}) \rightarrow \mathrm{H}_{2}\mathrm{CO}_{3}(\mathrm{aq})\)This option incorrectly shows carbon dioxide as a liquid (l).e) \(\mathrm{CO}_{2}(\mathrm{s})+\mathrm{H}_{2}\mathrm{O}(\mathrm{g}) \rightarrow \mathrm{H}_{2}\mathrm{CO}_{3}(\mathrm{s})\)This option incorrectly shows carbon dioxide as a solid (s), water as a gas (g), and carbonic acid as a solid (s).Based on the description and the analysis of the options, the correct chemical equation is:**b) \(\mathrm{CO}_{2}(\mathrm{g})+\mathrm{H}_{2}\mathrm{O}(\mathrm{l}) \rightarrow \mathrm{H}_{2}\mathrm{CO}_{3}(\mathrm{aq})\)**This equation accurately represents the reaction where carbon dioxide gas reacts with liquid water to produce aqueous carbonic acid.
