Chemistry-Mole Concept
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.
Correct Answer
Option A
Detailed Explanation
The stoichiometric coefficients indeed represent both the number of molecules and moles, as shown in the combustion of methane example where O2 has a coefficient of 2.
