In matter results in a change in its identity and properties.

The chemical change in matter is results in a change in its identity and properties.

Explanation:

There are toe type of changes physical change and chemical change.

The chemical change change in matter lead to lost its identity and properties.

Chemical change:

The changes, that occur due to change in the composition of a substance and result in a different compound is known as chemical change.

These changes are irreversible

These changes occur due to chemical reactions

These may not be observed with naked eye

Example:

Combustion of fuel or wood: that oil or wood convert into energy, CO2 and ash in case of wood

Boiling of egg: that change the chemical composition of protein in the egg .

The reaction of Hydrogen and oxygen:  

H 2 (g)  + O 2  (g) > 2H 2O  (l)

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.
