A compound is a pure substance made up of two or more elements that are chemically combined. An element is a pure - substance made of only one type of atom. A mixture is a combination of two or more substances that are not chemically combined. A homogeneous mixture has components that cannot be distinguished and appears as a single phase, while a heterogeneous mixture has distinguishable components. The process described in F is distillation. Based on the description in E, it matches the definition of a compound.
