Which of the following most likely happens during a chemical change? no new substances are formed. properties of a substance remain unchanged. composition of a substance is same as before. different atoms than before are introduced after the change

During a chemical change, different atoms are introduced after the change than before the change.

Explanation: Chemical reactions are defined as the reaction in which two or more substances react to form a new substance. The composition of the reactants change completely when the product is formed in a chemical reaction.

For example: Formation of rust when iron metal is exposed to air and moisture for a long time.

Equation follows:

So, During a chemical change, different atoms are introduced after the change than before the change.
