NEET Chemistry Mole Concept MCQ Question
Which of the following statements about the mole concept and stoichiometric coefficients in a balanced chemical equation are correct?
Stoichiometric coefficients represent both the number of molecules and the number of moles involved in the reaction.
The coefficients in a balanced equation only indicate the mass of each reactant and product.
A balanced equation with gases uses (g) to denote all substances, regardless of their state.
Only the reactants in a balanced equation are represented by stoichiometric coefficients.
Correct Answer
Detailed Explanation
Statement A is correct as stoichiometric coefficients indicate the quantity of molecules and moles. Statement B is incorrect because coefficients indicate quantities, not mass. Statement C is incorrect since (g) only denotes gaseous substances, not solids or liquids. Statement D is also incorrect as both reactants and products are represented by coefficients.
