Antoine Lavoisier is widely recognized as the "father of modern-day gimpppa.orgistry". That was one of the first to examine gimpppa.orgical reaction in detail. As part of his researches on the ingredient of the atmosphere, Lavoisier reaction mercury through oxygen to form mercuric oxide; he was then able to present that the decomposition the mercuric oxide produced mercury and oxygen.
You are watching: Which of the following reactions is a decomposition reaction
A decomposition reaction is a reaction in i m sorry a compound breaks down into two or more simpler substances. The general form of a decomposition reaction is:
Most decomposition reactions need an intake of power in the kind of heat, light, or electricity.
Binary compounds room compounds composed of just two elements. The simplest kind the decomposition reaction is as soon as a binary compound decomposes right into its elements. Mercury (II) oxide, a red solid, decomposes once heated to create mercury and oxygen gas.

<2 ceHgO left( s ight) ightarrow 2 ceHg left( l ight) + ceO_2 left( g ight)>
A reaction is also considered to it is in a decomposition reaction even when one or more of the products are quiet compounds. A metal carbonate decomposes right into a metal oxide and also carbon dioxide gas. Because that example, calcium lead carbonate decomposes into calcium oxide and also carbon dioxide:
Metal hydroxides decompose on heating to yield steel oxides and also water. Sodium hydroxide decomposes to create sodium oxide and also water:
<2 ceNaOH left( s ight) ightarrow ceNa_2O left( s ight) + ceH_2O left( g ight)>
Some rough acids decompose to produce nonmetal oxides and water. Carbonic mountain decomposes easily at room temperature right into carbon dioxide and also water:
