Question

What are the definition of the three types of chemical reactions?

Answer 1

Take your pick:
Displacement
Combustion
Neutralization
Combination
Decomposition

Explanation:

In a displacement reaction , an ion (or atom) in a compound is `color(red)("replaced")` by an ion (or atom) of another element.

A combustion reaction is a reaction in which a substance `color(red)("reacts with oxygen")`, usually with the release of heat and light to produce a flame.

A neutralization reaction is a reaction `color(red)("between an acid and a base")` Generally, aqueous acid-base reactions produce water and a salt

A combination reaction is a reaction in which `color(red)("two or more substances combine")` to form a single product.

Decomposition reactions are the opposite of combination reactions. Specifically, a decomposition reaction is the `color(red)("breakdown of a compound")` into two or more components.
