Explore how reactant amounts determine the products formed and the materials left over.

🎮 Try It
Choose a molecular reaction and change each reactant amount, then compare the products and leftovers. Use Sandwiches to test the same ratio idea with familiar ingredients.

🎯 Your Mission
Choose a reaction and vary one reactant at a time to identify the limiting reactant and explain the leftovers.

🌍 Real-World Connection
Chemists use reactant ratios to predict product yield and avoid wasting materials.
