Question

13.5 g al can produce 25.5 g al₂o₃.
32.0 g o₂ can produce 68.0 g al₂o₃.
which reactant is limiting?
o₂
al

Explanation:

Step1: Recall limiting reactant concept

The limiting reactant is the one that produces the least amount of product.

Step2: Compare product amounts

Al produces 25.5 g of \( \text{Al}_2\text{O}_3 \), and \( \text{O}_2 \) produces 68.0 g of \( \text{Al}_2\text{O}_3 \). Since 25.5 g < 68.0 g, Al produces less product.

Answer:

Al (the reactant Al is limiting because it produces a smaller amount of the product \( \text{Al}_2\text{O}_3 \) compared to \( \text{O}_2 \))
