Why do we say that a chemical change results in the formation of new substances? Give an example to illustrate your point.
Answer (2)
A chemical change results in new substances due to the rearrangement of atoms and bonds. For example, burning paper transforms it and oxygen into ash, carbon dioxide, and water vapor, forming entirely new products. This illustrates that chemical changes create substances with different properties from the original materials.

An example is the combustion of wood, which transforms wood and oxygen into ash, carbon dioxide, and water vapor. Thus, the original reactants become new products, illustrating the concept of chemical changes. ;
