Answer
The balanced chemical equation is:
$ 4 HCl(aq) + MnO_2(s) \rightarrow MnCl_2(aq) + 2 H_2O(l) + Cl_2(g)$
Work Step by Step
Aqueous hydrochloric acid $(HCl)$ and solid manganese(IV) oxide$(MnO_2)$ are the reactants.
Aqueous manganese(II) chloride $(MnCl_2)$, liquid water $(H_2O)$,
and chlorine gas $(Cl_2)$ are the products.
The balanced chemical equation is:
$ 4 HCl(aq) + MnO_2(s) \rightarrow MnCl_2(aq) + 2 H_2O(l) + Cl_2(g)$
