Question

Write the balanced equation of manganese$\left(IV\right)$ oxide and concentrated hydrochloric acid?

Answer 1

1. The chemical equation can be written as :
2. In these reaction manganese oxide react with dilute hydrochloric acid to form manganese chloride and water and chlorine gas evolved.
3. $$\begin{gathered} {\mathrm{MnO}}_2\left(\mathrm{s}\right)+4\mathrm{HCl}\left(\mathrm{aq}\right)\to {\mathrm{MnCl}}_2\left(\mathrm{aq}\right)+2{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)+{\mathrm{Cl}}_2\left(\mathrm{g}\right)\uparrow \\ (\mathrm{Manganese}(\mathrm{Hydrochloric}(\mathrm{Manganese}(\mathrm{water})(\mathrm{chlorine}\left) \\ \mathrm{oxide}\right)\mathrm{acid})\mathrm{chloride}) \end{gathered}$$
