Salt and pepper form a heterogeneous mixture. A) The components of a mixture do not have the same properties individually as they do when mixed. Question: Classify each of the following as a pure substance or a mixture; if it is a mixture, state whether it is heterogeneous or homogeneous: (a) concrete, (b) tomato juice, (c) marble, (d) seawater, and (e) iron. 3. Chocolate is made up of multiple ingredients (such as cocoa, oils, and sugar, as well as milk). Heterogeneous Mixtures: When two or more substances and mechanically mixed, they form a type of mixture whose. - Are similar to each other and different from those of Furthermore, thephysical properties, such as color, shine, density, and melting point, of a pure substance must be consistent throughout the entire sample. What is an example of a pure substance? A chocolate chip cookie is an example of a (2 points) a homogeneous Alcohol43. Describe the ability of a substance to change into a new substance.
