When sugar combines with oxygen to form these products, is it a physical or a chemical change, and why?
Responses
a physical change, because oxygen is involved in the change
a physical change, because oxygen is involved in the change
a physical change, because the atoms that make up sugar rearrange to form the products

The correct response is:
a chemical change, because the atoms that make up sugar rearrange to form the products.
In this process, known as cellular respiration, the sugar (glucose) and oxygen undergo a chemical reaction that rearranges the atoms, resulting in the formation of carbon dioxide and water. This change involves breaking and forming chemical bonds, which is characteristic of a chemical change.
