4. One of the two products of this reaction is carbonic acid (H2CO3), which immediately forms water and the gas you identified after exposure to the flaming and glowing splints. Write a balanced equation showing the decomposition of carbonic acid.

H₂CO₃ (aq) ⇒ H₂O (l) + CO₂ (g)

Explanation:

Carbonic acid dissociates into water and carbon dioxide which is gas which is used as a fire extinguisher and also which is identified after expose to the flaming and glowing splints. It is a colorless gas which can be identified by brisk effervescence seen in the tube.

The balanced reaction of the decomposition of carbonic acid is:

H₂CO₃ (aq) ⇒ H₂O (l) + CO₂ (g)
