Question

What is a chemical change????

Answer 1

Explanation:

Chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. These processes are called chemical reactions and, in general, are not reversible except by further chemical reactions.

Answer 2

A Chemical Change is one in which the molecular composition is completely altered and there is formation of a new product. The changes are irreversible and permanent. Mass is either added or removed. The energy changes occur during a chemical change.

Some of the examples of a Chemical Change are:

i) Burning of wood or paper

ii) Burning of candle

iii) Rusting of Iron

iv) Burning of camphor
