To balance the equation, start with the element that appears in the least number of compounds, which is often Aluminum (Al) in this case. The equation initially reads as Al2O3(s) + C(s) + Cl2(g) → AlCl3(s) + CO(g). Since Aluminum and Chlorine appear in a 1:3 ratio in AlCl3, and there are 2 Aluminum atoms in Al2O3, you need 2 Al2O3 to provide 4 Al atoms, which will react with 6 Cl2 to form 4 AlCl3. Carbon (C) and Oxygen (O) from CO balance last, ensuring the equation is stoichiometrically correct. The balanced equation is 2 Al2O3(s) + 3 C(s) + 6 Cl2(g) → 4 AlCl3(s) + 3 CO(g), making the coefficient of Al2O3 2.
