Chemical Equations and Reaction -

Chemical Equation

A symbolic representation of a chemical reaction showing reactants and products.

Reactants

Substances that undergo the chemical change in a reaction.

Products

Substances formed as a result of the chemical change.

Combination Reaction

A reaction where two or more reactants combine to form a single product.

Decomposition Reaction

A reaction in which a single compound breaks down into two or more simpler substances.

Displacement Reaction

A reaction in which an element in a compound is replaced by another element.

Double Displacement Reaction

A reaction where the ions of two compounds exchange places to form two new compounds.

Redox Reaction

A reaction involving the transfer of electrons between two species, involving simultaneous oxidation and reduction.

Balancing Chemical Equations

The process of ensuring the number of atoms of each element is the same on both sides of a chemical equation.

Law of Conservation of Mass

The principle that mass is neither created nor destroyed in a chemical reaction, thus equations must be balanced.
