Question

MnO2+HCl=MnCl2+Cl2+H2O

Answer 1

MnO2+4HCl→MnCl2+Cl2+2H20

Answer 2

The chemical equation you've written appears to be unbalanced. Let's balance it:

The unbalanced equation is:

MnO2 + HCl -> MnCl2 + Cl2 + H2O

To balance it, you need to ensure that there are the same number of each type of atom on both sides of the equation. Here's the balanced equation:

2 MnO2 + 4 HCl -> 2 MnCl2 + Cl2 + 2 H2O

Now the equation is balanced. It shows that when manganese dioxide (MnO2) reacts with hydrochloric acid (HCl), it produces manganese(II) chloride (MnCl2), chlorine gas (Cl2), and water (H2O).
