Why do decomposition reactions typically have compounds as

Solution 64P:

Step 1:

Redox reaction:

It is a reaction where the electrons transfer from one reactant to another.

For example:

The formation of water from the reaction of hydrogen and oxygen molecule.

There are three type of redox reactions:

1. Combination reactions:

In the combination reaction, two or more reactant combine together to form the product.

For example:

The formation of NH3 (g).

(b) Decomposition reactions

In the decomposition reaction, one reactant forms two or more products.

For example:

Thermal decomposition of KClO3(s)

(c) Displacement reactions:

In the displacement reaction, the number of atoms remain same for the reactant and product but the atoms exchange take place.

For example:

Zn(s) displaces the Cu2+ ion from CuSO4
