Answer:

During a chemical reaction, the substances that react are known as reactants whereas the substances that are formed during a chemical reaction are known as products. Six common types of chemical reactions are discussed below.

Types of Chemical Reactions EXPLANATION General Reaction

Combination reaction Two or more compounds combine to form one compound. A + B → AB

Decomposition reaction The opposite of a combination reaction – a complex molecule breaks down to make simpler ones. AB → A + B

Precipitation reaction Two solutions of soluble salts are mixed resulting in an insoluble solid (PRECIPITATE) forming. A + Soluble salt B → Precipitate + soluble salt C

Neutralization reaction An acid and a base react with each other. Generally, the product of this reaction is a salt and water. Acid + Base → Salt + Water

Combustion reaction Oxygen combines with a compound to form carbon DIOXIDE and water. These reactions are exothermic, meaning they give off heat. A + O2 → H2O + CO2

Displacement reaction One element takes place with ANOTHER element in the compound. A + BC → AC + B

1. Combination Reaction

A reaction in which two or more reactants combine to form a SINGLE product is known as a combination reaction.

It takes the form of X + Y → XY
