A sample containing 12.0 g of iron (Fe) is reacted with 10.0 g of chlorine gas (Cl₂) according to the equation \(2 \text{Fe} + 3 \text{Cl}_2 \rightarrow 2 \text{FeCl}_3\). The reaction gives an actual yield of 78 % based on the theoretical amount of FeCl₃. Calculate (a) the mass of FeCl₃ actually obtained and (b) the mass of iron that remains unreacted.

Answer Options

A. Mass of FeCl₃ obtained = 13.5 g; mass of unreacted Fe = 5.20 g
B. Mass of FeCl₃ obtained = 10.2 g; mass of unreacted Fe = 8.30 g
Correct Answer C. Mass of FeCl₃ obtained = 11.9 g; mass of unreacted Fe = 6.75 g
D. Mass of FeCl₃ obtained = 9.8 g; mass of unreacted Fe = 9.00 g
Correct Answer
C
Correct Option:
Mass of FeCl₃ obtained = 11.9 g; mass of unreacted Fe = 6.75 g
