Question

Balance the following equation(a). MnO2 + HCl —> MnCl2 +Cl2+H2O

Answer 1

`MnO_2+4HCl\rightarrow MnCl_2+Cl_2+2H_2O`

Step-by-step explanation

The given unbalanced equation is:

`MnO_2+HCl\rightarrow MnCl_2+Cl_2+H_2O`

Step 1: Balance the Mn atom on both sides of the equation:

`MnO_2+HCl\rightarrow MnCl_2+Cl_2+H_2O`

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:

`MnO_2+4HCl\rightarrow MnCl_2+Cl_2+H_2O`

Step 3: Balance the O and H atoms by putting 2 as the coefficient of H₂O on the right side of the equation:

`MnO_2+4HCl\rightarrow MnCl_2+Cl_2+2H_2O`

Hence, the balanced equation is:

`MnO_2+4HCl\rightarrow MnCl_2+Cl_2+2H_2O`
