Concept explainers
Interpretation:The decomposition reaction needs to be explained and classified.
Concept Introduction:A
A balance chemical reaction contains same number of atoms at both sides of the chemical reaction.

Answer to Problem 35A
Decomposition reaction can be defined as chemical reaction in which one of the substance decompose to two or more components of it.
It can be further classified as:
- Thermal decomposition reaction
- Electrolytic decomposition reaction
- Photo-decomposition reaction
Explanation of Solution
Given information: Decomposition reactions can be classified in different ways.
Decomposition reaction can be defined as chemical reaction in which one of the substance decompose to two or more components of it.
For example decomposition of HgO leads to formation of Hg metal and O2 gas.
It can be further classified as:
- Thermal decomposition reaction − Such decomposition reactions occur in the presence of high temperature.
- Electrolytic decomposition reaction − These decomposition reactions takes place due to the flow of electricity.
- Photo-decomposition reaction − These decomposition reactions occur in the presence of light.
Decomposition reaction can be defined as chemical reaction in which one of the substance decompose to two or more components of it.
It can be further classified as:
- Thermal decomposition reaction
- Electrolytic decomposition reaction
- Photo-decomposition reaction

Next, for each reaction to which you answered "Yes" to in the table, draw this product in the drawing area below. Note for advanced students: for this problem, don't worry if you think this product will continue to react under the current conditions - just focus on the first stable product you expect to form in solution. ?

H3O+ If this reaction will work, draw the major organic product or products you would expect in the drawing area below. If there's more than one major product, you can draw them in any arrangement you like. Be sure you use wedge and dash bonds if necessary, for example to distinguish between major products with different stereochemistry. 0 If the major products of this reaction won't have a new CC bond, just check the box under the drawing area and leave it blank. فا Explanation Check Click and drag to start drawing a structure.arrow_forward
