(40) GCSE Chemistry Revision "Limiting reactant"

Limiting Reactant

The reactant that is fully used up in a chemical reaction, determining the maximum amount of product that can be formed.

Excess Reactant

The reactant that remains after a chemical reaction has completed, as it was not fully consumed.

Reactants

The starting materials in a chemical reaction, which react to form products.

Products

The substances formed as a result of a chemical reaction.

Balanced Chemical Equation

An equation that has equal numbers of each type of atom on both sides, representing a chemical reaction.

Mole

A measurement in chemistry that represents a specific number of particles, typically 6.022 x 10²³.

Relative Formula Mass

The mass of one mole of a compound, calculated based on the atomic masses of the constituent elements.

Chemical Reaction

A process that leads to the transformation of one set of chemical substances to another.

Stoichiometry

The calculation of reactants and products in chemical reactions using mole ratios from the balanced equation.

Mass Calculation Formula

Mass = Number of moles x Relative formula mass.
