Answer
[tex]MnO_2+4HCl\rightarrow MnCl_2+Cl_2+2H_2O[/tex]Explanation
The given unbalanced equation is:
[tex]MnO_2+HCl\rightarrow MnCl_2+Cl_2+H_2O[/tex]Step 1: Balance the Mn atom on both sides of the equation:
[tex]MnO_2+HCl\rightarrow MnCl_2+Cl_2+H_2O[/tex]Step 2: Balance the Cl atom on both sides of the equation by putting 4 as the coefficient of HCl on the left side of the equation:
[tex]MnO_2+4HCl\rightarrow MnCl_2+Cl_2+H_2O[/tex]Step 3: Balance the O and H atoms by putting 2 as the coefficient of H₂O on the right side of the equation:
[tex]MnO_2+4HCl\rightarrow MnCl_2+Cl_2+2H_2O[/tex]Hence, the balanced equation is:
[tex]MnO_2+4HCl\rightarrow MnCl_2+Cl_2+2H_2O[/tex]
