NEET Chemistry Mole Concept Assertion Reason Question

Type: Assertion Reason-assertion-Hard-Class 11

Assertion (A): The stoichiometric coefficients in a balanced chemical equation also represent the ratio of moles of reactants and products. | Reason (R): The stoichiometric coefficients are determined by the law of conservation of mass, which states that mass can neither be created nor destroyed in a chemical reaction.

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 indicate the number of moles of each substance involved in the reaction, consistent with the law of conservation of mass, which ensures mass balance across the reaction.
