When blood passes through the lungs, carbon dioxide and water are formed from carbonic acid dissolved in the blood. The carbon d
ioxide formed passes into the lungs and is exhaled. H2CO3 H2O + CO2 What kind of reaction has occurred? combustion, combination decomposition, single-replacement, double-replacement
Balanced chemical reaction: H</span>₂CO₃ → CO₂ + H₂O. H₂CO₃ is carbonic acid. CO₂ is carbon (IV) oxide or carbon dioxide.<span>
Chemical decomposition is the separation of
a single chemical compound (in this example </span>carbonic acid<span>) into
its two or more simpler compounds (in this example water and
carbon dioxide).</span>
