What types of chemical reactions are there?

Coupling / synthesis reaction: Two or more substances combine to form a new compound (A + X -> AX). Includes, but is not limited to, reactions of elements with oxygen and sulfur; reactions of metals with halogens; and synthesis reactions with oxides.

Decomposition reactions: one constituent undergoes a reaction that produces two or more special substances (AX -> A + X).

Reactions with one substitution: when a substance in a compound is replaced by a substance outside the compound (A + BX -> B + AX). Possible substitutions include: metals with another metal; hydrogen in water with metal; Hydrogen in acid with metal.

Double substitution reactions: when the ions of two compounds exchange places in aqueous solutions to form two new compounds (AX + BY -> AY + BX). One of the compounds formed is usually a precipitate, an insoluble gas that bubbles out of solution, or a molecular compound (usually water).

Combustion reactions: When reactive elements combine with oxygen, releasing large amounts of energy in the form of light and heat (for example, burning wood, natural gas and gasoline). The formula looks like “hydrocarbon + oxygen -> [product]”.
