Antoine Lavoisier is widely known as the "father of modern-day brickandmortarphilly.comistry". That was one of the first to study brickandmortarphilly.comical reactions in detail. As component of his research studies on the ingredient of the atmosphere, Lavoisier reaction mercury through oxygen to type mercuric oxide; he was then able to display that the decomposition the mercuric oxide developed mercury and oxygen.

You are watching: Which of the following is a decomposition reaction?

Decomposition Reactions

A decomposition reaction is a reaction in i m sorry a compound division down right into two or more simpler substances. The general type of a decomposition reaction is:

Most decomposition reactions call for an input of power in the form of heat, light, or electricity.

Binary compounds space compounds composed of just two elements. The simplest kind of decomposition reaction is when a binary compound decomposes into its elements. Mercury (II) oxide, a red solid, decomposes once heated to produce mercury and also oxygen gas.

<2 ceHgO left( s ight) ightarrow 2 ceHg left( l ight) + ceO_2 left( g ight)>

Figure (PageIndex1): Mercury (II) oxide is a red solid. When it is heated, the decomposes into mercury metal and also oxygen gas. (CC BY-NC; CK-12)

A reaction is additionally considered to be a decomposition reaction even when one or much more of the products are still compounds. A steel carbonate decomposes into a metal oxide and also carbon dioxide gas. Because that example, calcium carbonate decomposes into calcium oxide and carbon dioxide:

Metal hydroxides decompose on heater to yield metal oxides and also water. Salt hydroxide decomposes to create sodium oxide and water:

<2 ceNaOH left( s ight) ightarrow ceNa_2O left( s ight) + ceH_2O left( g ight)>

Some turbulent acids decompose to produce nonmetal oxides and also water. Carbonic mountain decomposes quickly at room temperature right into carbon dioxide and water:
