검증된 단계별 안내1
Identify the oxide involved in the formation of carbonic acid. Carbonic acid is formed from carbon dioxide, which is a non-metal oxide.
Write the chemical formula for carbon dioxide (CO\_2) and water (H\_2O), the reactants in this reaction.
Understand that when carbon dioxide dissolves in water, it reacts to form carbonic acid (H\_2CO\_3).
Write the balanced chemical equation for the reaction: \(CO\_2 + H\_2O \rightarrow H\_2CO\_3\).
Recognize that this reaction is an example of an acid anhydride (carbon dioxide) reacting with water to form an acid (carbonic acid).
