Sugar must undergo a chemical change before it can be broken down into

carbon and water. Based on this information, what type of substance is

sugar?

O A a crystal

O B. a compound

O c. a transition element

OD. a heterogeneous mixture

B. a compound

Explanation: A mixture is a substance that is made of two or more components that are not chemically combined. For example a mixture of water and paraffin. A compound, on the other hand, is a pure substance that is made up of two or more atoms of different elements that are chemically joined together. Unlike an element which can not be broken by chemical means into simpler components, a compound can be chemically broken down to smaller substances such as smaller compounds or individual elements. Sugar is an example of a compound that is made up of carbon, hydrogen and oxygen atoms.
