Step 3: Determine the limiting reagent: From the balanced equation, 2 mol Al react with 3 mol Cl2. nAl : nCl2 = 0.185 mol : 0.099 mol = 1.87 : 1
Below is that a student might write about working through 12-4 practice problems in chemistry. It discusses the concepts, challenges, and insights — not just the answers. 12-4 Practice Problems Chemistry Answers

In most chemistry textbooks, Section 12.4 focuses on the relationship between balanced chemical equations and gas volumes (Gas Stoichiometry) or the mechanics of reaction rates (Chemical Kinetics).
2Al (s) + 3Cl2 (g) → 2AlCl3 (s)
