Explanation:
Detailed explanation-1: -In this reaction, carbonic acid decomposes to form water and carbon dioxide gas. Hence, this is the example of a decomposition reaction.
Detailed explanation-2: -Answer and Explanation: The reactant for this given reaction should be carbonic acid or a combination of (HCO−3 H C O 3 − )and hydrogen ions(H+ ).
Detailed explanation-3: -Carbon dioxide dissolves in water and slowly reacts with water to produce carbonic acid.
Detailed explanation-4: -What chemical reactions are going on inside a pop can? When CO2 dissolves in H2O, water and gaseous carbon dioxide react to form a dilute solution of carbonic acid (H2CO3). Note that the reactants, H2O and CO2, are on the left. The product, H2CO3, is on the right.
