A Chemical Change Difference

Explanation: "You start with one molecule and turn it into another. Chemical bonds are made or broken in order to create a new molecule. One example of a chemical reaction is the rusting of a steel garbage can." by www.chem4kids.com

"In a chemical reaction, the atoms and molecules that interact with each other are called reactants.

In a chemical reaction, the atoms and molecules produced by the reaction are called products.

In a chemical reaction, only the atoms present in the reactants can end up in the products. No new atoms are created, and no atoms are destroyed.

In a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products." by www.middleschoolchemistry.com
