The correct Answer is:
To solve the problem, we need to analyze the reaction between equal weights of elements X and Y, and determine the properties of the compound formed, X₂Y₃. ### Step-by-Step Solution: 1. **Identify the Atomic Weights**: - Atomic weight of X = 36 g/mol - Atomic weight of Y = 24 g/mol 2. **Assume Equal Weights**: - Let the equal weight of X and Y taken for the reaction be 'a' grams. 3. **Calculate the Initial Moles**: - Moles of X = \( \frac{a}{36} \) - Moles of Y = \( \frac{a}{24} \) 4. **Write the Balanced Chemical Equation**: - The balanced reaction is: \[ 2X + 3Y \rightarrow X_2Y_3 \] 5. **Determine the Stoichiometry**: - According to the balanced equation, 2 moles of X react with 3 moles of Y. - From the moles calculated: - For X: \( \frac{a}{36} \) moles - For Y: \( \frac{a}{24} \) moles 6. **Find the Limiting Reagent**: - To find which reactant is limiting, we can set up a ratio based on the stoichiometry: - Required moles of Y for the available moles of X: \[ \text{Required moles of Y} = \frac{3}{2} \times \frac{a}{36} = \frac{3a}{72} \] - Compare this with the available moles of Y: \[ \frac{a}{24} \] - Since \( \frac{3a}{72} = \frac{a}{24} \), both reactants are consumed completely, indicating that there is no limiting reagent. 7. **Calculate the Moles of the Product (X₂Y₃)**: - The moles of X₂Y₃ formed can be calculated as: \[ \text{Moles of } X_2Y_3 = \frac{a}{72} \] 8. **Calculate the Molar Mass of X₂Y₃**: - Molar mass of X₂Y₃: \[ \text{Molar mass} = 2 \times 36 + 3 \times 24 = 72 + 72 = 144 \text{ g/mol} \] 9. **Calculate the Weight of X₂Y₃ Formed**: - Weight of X₂Y₃ = Moles × Molar Mass: \[ \text{Weight of } X_2Y_3 = \left(\frac{a}{72}\right) \times 144 = 2a \] 10. **Conclusion**: - The mass of X₂Y₃ formed is double the mass of Y taken (since Y was taken as 'a' grams). - Therefore, the statements regarding the limiting reagent and the mass of the product formed can be evaluated based on this analysis. ### Final Answers: - The correct options are: - The mass of X₂Y₃ formed is double the mass of Y taken. - There is no limiting reagent.

To solve the problem, we need to analyze the reaction between equal weights of elements X and Y, and determine the properties of the compound formed, X₂Y₃. ### Step-by-Step Solution: 1. **Identify the Atomic Weights**: - Atomic weight of X = 36 g/mol - Atomic weight of Y = 24 g/mol ...
