Answer to Question #140756 in General Chemistry for Ahmad Iskander

Question

what is the greatest amount of chlorine gas that can be made when 4 moles of react with 4 moles of Oas the following reaction? 4FeCL + 30(2) :2Fe(2)O(3)+6Cl(2)

Answer 1

FeCl₃ can reacts with O₂ as follows:

4FeCl₃ + 30₂ -----> 2Fe₂O₃ + 2Cl₂

4 moles of FeCl₃ reacts with 3 moles of O₂ to produce 2 moles of Cl₂ gas

When 4 moles of FeCl₃ is available and 4 moles of O₂ is available,

then 3 moles of O₂ reacts with 4 moles of FeCl₃ to give 2 moles of Cl₂

Hence, 2 moles is the greatest amount of Chlorine gas that can be obtained when 4 moles of FeCl₃ reacts with 4 moles of O₂
