Limiting reactant
In a real reaction, reactants are not always present in the exact proportions of the equation. The limiting reactant is consumed first and sets the maximum amount of product.
Core idea

A concrete example
Think of a recipe: if each assembly needs two A pieces and one B piece, ten A pieces but only three B pieces can make only three assemblies.
Why it matters
This concept connects symbolic scientific language with what actually happens at atomic, molecular or experimental scales. Before applying a formula, always check the quantities, units and assumptions of the model.
Check it yourself
Restate the idea without technical vocabulary, then repeat the reasoning with a simple value. If your explanation and calculation tell different stories, revisit the assumptions.
