Question

When blood passes through the lungs, carbon dioxide and water are formed from carbonic acid dissolved in the blood. The carbon dioxide formed passes into the lungs and is exhaled. H2CO3 H2O + CO2 What kind of reaction has occurred? combustion, combination decomposition, single-replacement, double-replacement

Answer 1

for plato its C, decomposition

Step-by-step explanation:

Answer 2

Answer is: decomposition.

Balanced chemical reaction: H₂CO₃ → CO₂ + H₂O.
H₂CO₃ is carbonic acid.
CO₂ is carbon (IV) oxide or carbon dioxide.
Chemical decomposition is the separation of a single chemical compound (in this example carbonic acid) into its two or more simpler compounds (in this example water and carbon dioxide).
