Solid aluminum and gaseous oxygen react in a combination reaction to produce aluminum oxide: 4Al (s) + 3O₂ (g) → 2Al₂O₃ (s)
In a particular experiment, the reaction of 2.5 g of Al with 2.5 g of O₂ produced 3.5 g of Al₂O₃. The % yield of the reaction is ________.

Question

Quizplus · Accepted Answer

The theoretical yield of Al₂O₃ is calculated based on the limiting reactant. Al is the limiting reactant, producing 4.72 g of Al₂O₃. The % yield is (3.5 g / 4.72 g) * 100 = 74%.
