Question
In the reaction: MnO₂ + 4HCl → MnCl₂ + Cl₂ + 2H₂O, if 4.35 g MnO₂ (M=87) is taken with excess HCl, volume of Cl₂ at STP is:
- A0.56 L
- B1.12 LCorrect
- C2.24 L
- D0.28 L
Correct answer
1.12 L
Explanation
n(MnO₂) = 4.35/87 = 0.05 mol. 1 mol MnO₂ → 1 mol Cl₂. n(Cl₂) = 0.05 mol. V = 0.05 × 22.4 = 1.12 L.
