Key Concepts

Balanced Chemical Equations

A balanced chemical equation is a representation of a chemical reaction where the number of atoms for each element is equal on both the reactant and product sides. This balancing ensures the law of conservation of mass is upheld, meaning atoms are neither created nor destroyed during the reaction. The process involves adjusting the coefficients (the numbers in front of compounds or elements) to achieve an equal count of each type of atom on both sides of the equation.

Limiting Reactant

The limiting reactant is the substance in a chemical reaction that is completely consumed first, thus limiting the amount of product that can be formed. It is determined by comparing the mole ratios of the reactants as given by the balanced equation to the actual amounts available. Understanding the limiting reactant is crucial in stoichiometry because it directly influences the theoretical yield of the reaction and helps to calculate how much of each reactant is needed.
