NEET Chemistry Mole Concept Assertion Reason Question

Type: Assertion Reason-assertion-Medium-Class 11

Assertion (A): The stoichiometric coefficients in a balanced chemical equation represent both the number of molecules and the number of moles involved in the reaction. | Reason (R): In the combustion of methane, the stoichiometric coefficient of oxygen is 2, indicating two molecules and moles of oxygen are required.

A

Both A and R are true and R is the correct explanation of A.

B

Both A and R are true but R is not the correct explanation of A.

C

A is true but R is false.

D

A is false.
