Question

what is a redox reaction? identify the substance oxidized and substance reduced in the following reatior (1) MnO2+4HCL---------------------MnCl2+2H2O+Cl2 (2) CuO+H2----------------- Cu+H2o​

Answer 1

a redox reaction is a reaction in which both oxidation and reduction happen simultaneously..

1 MnO2 is reduced to MnCl2 and HCl is oxidised to Cl2

2 CuO is reduced to Cu and H2 is oxidised to H2O....

hope it helps you ☺️

Answer 2

Redox is a type of chemical reaction in which the oxidation states of atoms are changed. Redox reactions are characterized by the transfer of electrons between chemical species, most often with one species undergoing oxidation while another species undergoes reduction

1.) MnO2 is getting reduced and HCl is getting oxidized

2.) CuO is getting reduced and H2 is getting oxidized
