Question

question 25 of 28 which of the following is the correct balanced equation for the breakdown of carbonic acid (h2co3) into water and carbon dioxide? a. 2h2co3 → h2o + 3co2 b. 2h2co3 → 2h2o + 3co2 c. h2co3 → h2o + 3co2 d. h2co3 → h2o + co2

Explanation:

The decomposition of carbonic acid (H₂CO₃) produces water (H₂O) and carbon dioxide (CO₂). A balanced equation has equal atoms on both sides. For H₂CO₃ → H₂O + CO₂: H (2=2), C (1=1), O (3=3), all balanced.

Answer:

D. H₂CO₃ → H₂O + CO₂
