Limiting Reagent Calculator

Calculate limiting reagent in chemical reactions to determine which reactant runs out first. Enter balanced equation (CH₄ + 2O₂ → CO₂ + 2H₂O) and reactant amounts (mass or moles) to find limiting reagent, excess reagent, and product formed. Uses formula: Limiting Reagent = smallest (moles / coefficient). Features common reactions (combustion, Haber process, rust formation, etc.) and step-by-step solutions. Perfect for chemistry students.
