Answer:

4Al (s) + 3O₂ (g) → 2Al₂O₃

General Formulas and Concepts:

Chemistry - Reactions

  • Reaction Prediction
  • Balancing RxN's

Explanation:

Step 1: Define RxN

Al (s) + O₂ (g) → Al₂O₃

Step 2: Balance RxN

4Al (s) + 3O₂ (g) → 2Al₂O₃

  • Need to balance the amount of oxygens on both sides
  • If we balance the oxygens, the aluminums will also have to be rebalanced
