Answer 2

Answer:

Chemical reaction is irreversible and permanent.

Explanation:

• A chemical change is the transformation of one material into another, the formation of new materials with distinct properties, and the formation of one or more new substances.
• It occurs when one substance combines with another to form a new substance (synthesis or either decomposes to form more substances).
• Burning, cooking, rusting, and rotting are all examples of chemical changes. Boiling, melting, freezing, and shredding are examples of physical changes.
• A chemical reaction is the only way to reverse a chemical change.
• In a chemical change, the atoms in the reactants rearrange and bond differently to form one or more new products with different properties than the reactants.
