Question

What is redox reaction? Idetify the substances oxidised and the substance reduced in the following reactions.
(a)MnO3+4Hcl=MnCl2+Cl2+H2O
(b) CuO+H2=Cu+H2O
please answer it fast!!!!!

Answer 1

Answer:

a reaction in which reduction and oxidation take place simultaneously.

1.mno3 is reduced and hcl is oxidised

2.cup is oxidised and h2 is reduced

Answer 2

A REACTION IS WHICH THERE IS BOTH OXIDATION AND REDUCTION IS CALLED REDOX REACTION

@) In the reaction MnO2 + 4HCl -> MnCl2 + Cl2 + 2H2O , Cl (chlorine) is the substance which is oxidized from the HCl, and it is the reducing agent for the MnO2 as well. As Cl is the oxidized substance in HCl, thus it is the oxidizing agent in the reaction.

ß) cuo is reduced and h2 is oxidised
