Question

explain decomposition reaction is involved in redox reaction​

Answer 1

Answer:

In decomposition reactions, a compound is broken down into its constituent parts. ... In combustion reactions, a compound reacts with oxygen to produce carbon dioxide, water, and heat. In disproportionation reactions, a molecule is both reduced and oxidized; these types of reactions are rare.

Answer 2

$answer$

Decomposition reactions are the reverse of combination reactions, meaning they are the breakdown of a chemical compound into its component elements.

General equation: AB → A + B

Sample 2. equation: 2 H2O → 2 H2 + O2

Calculation: (2)(+1) + (-2) = 0 → 0 + 0

In this equation, the water is “decomposed” into hydrogen and oxygen, both of which are neutral. Similar to the previous example, H2O has a total oxidation state of 0, with each H taking on a +1 state and the O a -2; thus, decomposition oxidizes oxygen from -2 to 0 and reduces hydrogen from +1 to 0.
