what is interfacial tension in liqui liquid extraction?
Answer:
0.675 mol
Explanation:
Step 1: Write the balanced equation
2 Al + Fe₂O₃ ⇒ 2 Fe + Al₂O₃
Step 2: Establish the appropriate molar ratio
According to the balanced equation, the molar ratio of Fe to Al₂O₃ is 2:1.
Step 3: Calculate the moles of Al₂O₃ produced when 1.35 moles of Fe are produced
We will use the established molar ratio.
1.35 mol Fe × 1 mol Al₂O₃/2 mol Fe = 0.675 mol Al₂O₃
