Question

Match the correct chemical equation to the following chemical reaction: Carbonic acid (as found in soft drinks) decomposes into water and carbon dioxide.

H2CO3(aq) → H2O(l) + CO2(g)

H2O(l) + C → H2CO3(aq)

H2O(l) + CO2(g) → H2CO3(aq)

H2CO3(aq) → CO2(g) + O2

Answer 1

The correct chemical equation for the decomposition of carbonic acid into water and carbon dioxide is:

H2CO3(aq) → H2O(l) + CO2(g)
