Question

write a balance chemical equation for the initial reaction of aqueous hydrochloric acid with aqueous sodium carbonate. (this reaction occurs in our blood and leads to iliminate of co2(g) by our lungs)

Answer 1

The balanced chemical equation is :

Na₂CO₃ (aq) + 2 HCl (aq) $\rightarrow$ 2 NaCl (aq) + H₂O (l) + CO₂ (g)

The carbon dioxide gas CO₂ produced in this reaction is eliminated through lungs while breath is exhaled from the body.
