Question

what is redox reaction? Identify the substance oxidized and substance reduced in the following reaction :- (1). MnO2 + 4HCl = MnCl2 + 2H2O + Cl2 , (2). CuO + H2 = Cu + H2O

Answer 1

Answer: this reaction take place where some element is oxidized And the another is reduced to oxygen.

(1)Mn is reduced and H is oxidised

(2)Cu is reduced and H is oxidised

Answer 2

Answer:

Explanation: REDOX REACTION

THE REACTIONS IN WHICH OXIDATION AND REDUCTION OCCURR SIMULTANEOUSLY ARE CALLED REDOX REACTION.

1)HERE,

MANGNESE(Mn) IS REDUCED AND HYDROGEN(H) , CHLORINE(C)l IS OXIDISED.

2)HERE,

COPPER(Cu) IS REDUCED AND HYDROGEN(H2) IS OXIDISED.
