Question

MnO2+HCl=MnCl2+H2O+Cl2 Balance it by Oxidation Number Method?????​

Answer 1

Explanation:

we know that oxidation is removal of H2 and gaining of O2 whereas reduction is addition of H2 and removal of O2

thus,

MnO2 --------> MnCl2 (Reduction) (oxidising agent)

HCL. --------> Cl2 (Oxidation) (reducing agent )

Answer 2

Explanation:

MnO2---------->MnCl2

(reduction)so it is oxidising agent

HCl-------------->Cl2

(oxidation) so it is reducing agent
