This program was created with a lot of help from: The book "Parsing Techniques - A Practical Guide" (IMHO, one of the best computer science books ever written. A certain reaction has the following general form. 26 mol O2 are availiable? Apparently the limiting reactant is Al, but I don't understand why. The coefficients in the following reaction 2Al2O3 → 4Al + 3O2 add up to 7. Label them oxidation and reduction. Aluminum oxide is formed from the reaction of metallic aluminum with oxygen gas. Write a balanced equation for this reaction. You need to use the half reaction method or the ion electron method to balance the redox reaction. 0 grams of O2? Reaction: 4Al + 3O2 ? 2Al2O3. 4Al + 3O2 → 2Al2O3 12.
