What is the main identification of a chemical change?

Answer and explanation

Correct answer: Formation of a new substance

In a chemical change, the chemical composition of a substance changes and one or more new substances are formed. Therefore, formation of a new substance is its main identification. A change only in shape or state, such as melting of ice, is usually a physical change because no new substance is produced. Exam tip: rusting, burning, and curdling of milk are common examples of chemical changes.
