No.

#### Explanation:

Hydrochloric acid, $\text{HCl}$, is a strong acid that ionizes completely in aqueous solution to form hydronium cations< ${\text{H"_3"O}}^{+}$, and chloride anions, ${\text{Cl}}^{-}$

color(red)("H")"Cl"_ ((aq)) + "H"_ 2"O"_ ((l)) -> "H"_ 3"O"_ ((aq))^(color(red)(+)) + "Cl"_((aq))^(-)

Calcium chloride, ${\text{CaCl}}_{2}$, is a soluble ionic compound that dissociates completely in aqueous solution to form calcium cations, ${\text{Ca}}^{2 +}$, and chloride anions

${\text{CaCl"_ (2(aq)) -> "Ca"_ ((aq))^(2+) + "Cl}}_{\left(a q\right)}^{-}$

As you can see, both hydrochloric acid and calcium chloride dissociate in aqueous solution. After they dissociate, these ions will continue to exist in solution as such.

Adding calcium chloride to a solution of hydrochloric acid will thus result in a solution that contains ${\text{Ca}}^{2 +}$, ${\text{H"_3"O}}^{+}$, and ${\text{Cl}}^{-}$.

These ions will not react with each other in any way, which is why you can say that calcium chloride and hydrochloric acid do not react when mixed.

"Ca"_ ((aq))^(2+) + "Cl"_ ((aq))^(-) + "H"_ 3"O"_ ((aq))^(+) + "Cl"_((aq))^(-) -> color(red)("no reaction")

This is of course equivalent to

"CaCl"_ (2(aq)) + "HCl"_ ((aq)) -> color(red)("no reaction")#
