Question

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

H2(g) + CO2(g) → H2CO3(g)
H2O(l) + CO2(g) → H2CO3(g)
H2CO3(g) → H2(g) + CO2(g)
H2CO3(g) → H2O(l) + CO2(g)

Answer 1

Carbonic acid's chemical formula is H2CO3.  Its decomposition to water (H2O) and carbon dioxide (CO2) is represented by the equation:

H2CO3(g) → H2O(l) + CO2(g)

Answer 2

"formation of water and carbon dioxide" are H2O and CO2

ans is H2CO3(g) → H2O(l) + CO2(g)
