Key Concepts

Limiting Reactant

The limiting reactant is the substance in a chemical reaction that is completely consumed first, thereby determining the maximum amount of product that can be formed. In stoichiometric calculations, identifying the limiting reactant involves comparing the mole ratios of the reactants as dictated by the balanced chemical equation.

Stoichiometry

Stoichiometry involves the quantitative relationships between reactants and products in a chemical reaction. It uses the mole ratios from the balanced equation to calculate the amount of products expected from given amounts of reactants, ensuring that mass and atoms are conserved.

Ideal Gas Law

The ideal gas law (PV = nRT) is a fundamental equation in chemistry that relates the pressure, volume, temperature, and number of moles of a gas. This law is pivotal when working with gaseous substances, as it allows one to convert between measurable properties (like pressure) and the number of moles involved in a reaction.

Partial Pressure

Partial pressure is the pressure contributed by an individual gas component in a mixture of gases. It is used, along with the ideal gas law, to determine the number of moles of a gas present in a reaction vessel, which is essential for carrying out stoichiometric calculations in reactions involving gases.
