Question

Certainly! To determine the mass of aluminum oxide (Al₂O₃) formed, we need the balanced chemical equation for the reaction between aluminum (Al) and oxygen (O₂). Once we have the balanced equation, we can use the given masses of aluminum and oxygen to find the limiting reactant and calculate the mass of aluminum oxide produced. Do you have the balanced equation for this reaction?

Answer 1

The balanced equation for the formation of aluminum oxide is 4Al + 3O₂ → 2Al₂O₃.

Step-by-step explanation:

a) To determine the mass of aluminum oxide formed, we need to know the masses of aluminum and oxygen.

Let's say we have 5 grams of aluminum and 8 grams of oxygen.

First, we calculate the moles of aluminum by dividing the mass by the molar mass of aluminum.

Next, we calculate the moles of oxygen by dividing the mass by the molar mass of oxygen.

b) To find the limiting reactant, we compare the moles of aluminum and oxygen and determine which one is in lesser quantity. Then, we use the mole ratio from the balanced equation to calculate the mass of aluminum oxide formed.

c) The balanced equation for the formation of aluminum oxide (Al₂O₃) is: 4Al + 3O₂ → 2Al₂O₃
