Consider the hypothetical chemical reaction represented by the equation 3 A + 2 B $\rightarrow$ A₃B₂ Which of the following is a correct interpretation of this equation?
(i) 3 grams of A react with 2 grams of B to form 1 gram of A₃B₂
(ii) 3 atoms of A react with 2 atoms of B to form 1 molecule of A₃B₂
(iii) 3 moles of A react with 2 moles of B to form 1 mole of A₃B₂

Question

Consider the hypothetical chemical reaction represented by the equation 3 A + 2 B

\rightarrow

A₃B₂ Which of the following is a correct interpretation of this equation?
(i) 3 grams of A react with 2 grams of B to form 1 gram of A₃B₂
(ii) 3 atoms of A react with 2 atoms of B to form 1 molecule of A₃B₂
(iii) 3 moles of A react with 2 moles of B to form 1 mole of A₃B₂

Quizplus · Accepted Answer

The equation represents a stoichiometric relationship, meaning it describes the ratio of moles or molecules, not grams. Therefore, (ii) and (iii) are correct interpretations, as they describe the reaction in terms of atoms/molecules and moles, respectively.
