Final answer:
It is true that chocolate chip cookies are a mixture because they are composed of multiple substances that are physically combined without chemical bonding, allowing for separation.
Step-by-step explanation:
The statement that chocolate chip cookies are a mixture because they have 2 or more substances (compounds and molecules) that are physically mixed together, but not chemically bonded, is true. This means that the parts retain their individual properties and can still be identified and separated physically. Chocolate chip cookies are an example of a heterogeneous mixture, where components such as chocolate chips, nuts, and cookie dough can be visually distinguished and separated from each other. Unlike compounds, where elements chemically combine to create substances with different properties, mixtures maintain the properties of their individual substances.
