Answer:

C. 1.

Explanation:

Hello!

In this case, given the reaction:

[tex]2HCl+CaCO_3\rightarrow CaCl_2 +CO_2 +H_2O[/tex]

Thus, since there is a 2:1 mole ratio between HCl and CO2, as we are given 2 mol HCl, we compute the moles of CO2 as shown below:

[tex]n_{CO_2}=2molHCl*\frac{1molCO_2}{2molHCl}=1molCO_2[/tex]

Thus, the answer is C. 1.
