Answer:

#4.0# mol #"CO"_2#

Explanation:

The chemical equation for this reaction is

#"H"_2"CO"_3"(aq)" rightleftharpoons "CO"_2"(g)" + "H"_2"O(l)"#

You'll notice that all the reagents in this reaction have equal amounts of relative moles, so if #4.0# moles of #H_2CO_3# decomposes completely, there will be #4.0# moles of each water and carbon dioxide produced.

Answer:

Four (4).

Explanation:

Carbonic acid is a chemical compound with the chemical formula #H_2CO_3#.
Thus, each mole of carbonic acid can only produce one mole of carbon dioxide because there is only one mole of carbon per mole of carbonic acid.
