Which chemical equation correctly represents the formation of water and carbon dioxide from the decomposition of carbonic acid in soft drinks?

Carbonic acid refers to a weak inorganic acid, which is also known as the solution of carbon dioxide in water. It only prevails as a solution and is also known as the aerial acid, acid of air, dihydrogen carbonate, or carbon dioxide solution. It is most familiar as a constituent of the majority of the aerated drinks like soft drinks and sodas.  

The carbonic acid's chemical formula is H₂CO₃. Its decomposition to water and carbon dioxide is shown by the equation:  

H₂CO₃ (g) = H₂O (l) + CO₂ (g)

the molecules move in straight line until they collide with each other or with the walls of the container. collisions are perfectly elastic; when two molecules collide, they change their directions and kinetic energies, but the total kinetic energy is conserved.
