Hey mate answer your question is given below by me.
Explanation:
Major Types of Chemical Reactions
Five major types of chemical reactions: synthesis, decomposition, combustion, single replacement (also called single displacement) and double replacement (also called double displacement).
In a synthesis reaction, a compound is made from more simple materials.
In a decomposition reaction, a compound breaks down into simpler elements or compounds.
In a combustion reaction, a compound (usually with carbon, hydrogen, and sometimes oxygen) combines with oxygen to give carbon dioxide and water.
In a single replacement (displacement) reaction, one element that is on its own displaces another element in aqueous solution, kicking it out.
In a double replacement (displacement) reaction, the positive and negative ions in two ionic compounds switch places, causing a precipitate to form.

Introduction to Oxidation Reduction (Redox) Reactions
An oxidation reduction (redox) reaction happens when electrons are transferred between atoms.
A loss of electrons is called oxidation, and we say that atom has become oxidized.
A gain of electrons is called reduction, and we say that the atoms has become reduced.
The two separate parts (oxidation and reduction) of an oxidation reduction (redox) reaction are called half reactions.
Two half reactions can be put together to make the whole reaction.
Oxidation numbers are numbers that can be written above atoms to show whether they are gaining or losing electrons.

Oxidizing Agents and Reducing Agents
Oxidizing agents make oxidation happen, and reducing agents make oxidation happen.
An oxidizing agent takes electrons from something, allowing it to be oxidized, and a reducing agents gives electrons to something, allowing it to be reduced.
You can remember this by noting that the thing that is reduced is the oxidizing agent, and the thing that is oxidized is the reducing agent.
We'll then look at some equations and identify the oxidizing and reducing agents. To do this, we have to write oxidation numbers (or oxidation states) for the elements in the equation, and then figure out how electrons are moving, what is being oxidized and what is being reduced.
