Types of reactions

Combustion is a rapid, exothermic chemical reaction where a substance reacts with oxygen, producing heat and light. It typically involves the burning of fuels, such as hydrocarbons, and can result in the formation of new gases like carbon dioxide and water vapor. Corrosion, on the other hand, is a slow, steady process that occurs when a metal reacts with oxygen or moisture, leading to the deterioration of the metal. This process can result in the formation of rust and other oxidation products, affecting the material’s integrity and appearance.

A precipitation reaction is a chemical reaction in which two dissolved substances react to form an insoluble solid called a precipitate.

A neutralisation reaction is a chemical reaction in which an acid and a base react to form a salt and water, effectively neutralising each other.

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

A synthesis reaction is a chemical reaction in which two or more reactants combine to form a single, more complex product.
