Question

7. What is a redox reaction? Identify the substances oxidised and the substances reduced in the
following reactions:
(a) MnO2 + 4HCl- → MnCl2 + 2H2O + Cl2
(b) CuO+H2 --Cu + H2O​

Answer 1

Explanation:

the reaction in which one reactant is getting oxidised and other reactant gets reduced is called a redox reaction

a)Mn is reduced and H got oxidised to form water

b)cu is reduced and H is oxidised

Answer 2

Answer:

Here,is your answer

The reaction which involve simultaneously Oxidation and reduction is called an Oxidation reaction OR Red ox reaction

Mn O2+4 HCL--->Mn cl 2 +2 H 2O +Cl 2 |

Cu o +H2-->Cu+H 2 O
