(a) The reactions in which one reactant gets oxidized while the other gets reduced during the reaction are called oxidation-reduction reactions or redox reactions.

(b) The reaction between manganese dioxide and hydrochloric acid is a redox reaction because MnO2 is reduced to MnCl2 and HCl is oxidized to H2O.

 MnO2 + 4HCl → MnCl2 + Cl2 + 2H2O

(c) Oxidizing agent - HCl Reducing agent - MnO2
