Displacement
Combustion
Neutralization
Combination
Decomposition

#### Explanation:

In a displacement reaction , an ion (or atom) in a compound is $\textcolor{red}{\text{replaced}}$ by an ion (or atom) of another element.

A combustion reaction is a reaction in which a substance $\textcolor{red}{\text{reacts with oxygen}}$, usually with the release of heat and light to produce a flame.

A neutralization reaction is a reaction $\textcolor{red}{\text{between an acid and a base}}$ Generally, aqueous acid-base reactions produce water and a salt

A combination reaction is a reaction in which $\textcolor{red}{\text{two or more substances combine}}$ to form a single product.

Decomposition reactions are the opposite of combination reactions. Specifically, a decomposition reaction is the $\textcolor{red}{\text{breakdown of a compound}}$ into two or more components.
