What is decomposition in a chemical reaction?

Answer 1

Decomposition reaction is a chemical reaction that is the opposite of synthesis. In decomposition, a single compound breaks down into two or more simpler substances.

AB --> A + B

An example of this is the decomposition of zinc carbonate, represented by the equation: ZnCO3(s) --> ZnCO(s) + CO2(g) . Likewise CaCO3 (s) --> CaO (s) + CO2 (g)
the decomposition reaction is easy it is so easy i dont know even know what it is so bye and dont go to ask.com you will end up getting in trouble.

Answer 2

Its a reaction which "breaks down" one molecule or compound into smaller molecules or atoms.

Examples:

AB ------> A + B

or water elctrolysis:

2H2O ----> 2H2 + O2.

Answer 3

Decomposition reactions are those in which one reactant splits into two or more products. Only those decomposition reaction are redox reactions in which minimum one of the products is an element.
Example-
2 H2O ---> 2H2 + O2

Answer 4

A decomposition reaction is where one single compound breaks down into two or more simpler chemicals. An example of this is the decomposition of zinc carbonate, represented by the...

Answer 5

A reaction in which a single compound breaks down to form two of more simple substances.

Answer 6

is a reaction where the molecular compound decomposes into its elements ..or an ionic compound decomposes to its ions

Answer 7

Decomposition is the breaking down of reactants in the chemical reaction.

Answer 8

When an element decomposes to form two or more compounds, it is called decomposition reaction. Eg.- electrolysis of water.

Answer 9

one reactant breaks down to form more than one products (apex)
