Which of the following gases is evolved when dilute hydrochloric acid ( $HCl$ ) reacts with calcium trioxocarbonate(IV) ( $CaCO_3$ )?

Carbon(IV) oxide (

CO_2

)

A characteristic chemical property of acids is that they react with trioxocarbonate(IV) salts (such as

CaCO_3

) to produce a salt, water, and carbon(IV) oxide gas (

CO_2

Identify the reactants and the class of reaction

Dilute hydrochloric acid (

HCl

) reacts with calcium trioxocarbonate(IV) (

CaCO_3

), which is an acid-carbonate reaction.

Acids characteristically react with trioxocarbonates to form salt, water, and carbon dioxide.

Write the balanced chemical equation

2HCl(aq) + CaCO_3(s) \rightarrow CaCl_2(aq) + H_2O(l) + CO_2(g)

The equation shows that carbon(IV) oxide gas (

CO_2

) is liberated during the chemical process.
