Question

define and give examples of following types of reaction 1. displacement reaction 2. decomposition reaction ​

Answer 1

Answer:

DECOMPOSITION REACTION - DEFINITION

A decomposition reaction is a type of chemical reaction in which a single compound breaks down into two or more elements or new compounds. These reactions often involve an energy source such as heat, light, or electricity that breaks apart the bonds of compounds. For

example,

CaCO 3 →CaO+CO2

Displacement reaction :

A single-displacement reaction, also known as a single-replacement reaction, is a reaction by which one

(or more) element(s) replaces an/other element(s) in a compound. It can be represented generally as:

A+B−C→A−C+B
