-2 below :
(a) Both (A) and (R) are true and (R) is the correct explanation of tł
assertion (A)
(b) Both (A) and (R) are true, but (R) is not the correct explanation
the assertion (A).
(c) (A) is true, but (R) is false.
(d) (A) is false, but (R) is true.
Assertion (A):
The reaction
MnO2 + 4HCl → MnCl2 + 2H2O + Cl2
is an example of a redox reaction.
In this reaction, HCI is reduced to Cl2 whereas MnO
oxidised to MnCl2
Reason (R):
13​

Answer 1

Answer:

potion c is correct

MnO2 gets reduced and 4HCl gets oxidised

Answer 2

C) A is True but R is false.

• The given reaction is MnO2 + 4HCl → MnCl2 + 2H2O + Cl2.
• The given reaction involves oxidation and reduction of the elements. So, this is a redox reaction.
• The Mn is reduced from +4 to +2 oxidation state in MnCl2.
• The Cl is oxidized to Cl2
• HCl is oxidized to Cl2, MnO is reduced to MnCl2
