Answer:
Step-by-step explanation:
Ans (A)- Homogeneous mixtures (solutions) can be separated into their component substances by physical processes that rely on differences in some physical property, such as differences in their boiling points.
Ans (B)- A heterogeneous mixture is a mixture of two or more chemical substances (elements or compounds) where the different components can be visually distinguished and easily separated by physical means. Examples include: mixtures of sand and water.
Ans (C)- Components of a homogeneous mixture cannot be separated by using physical methods.
Reason
Composition of homogeneous mixture is uniform throughout as the components react to form a single compound.
Components of a homogeneous mixture cannot be separated by using physical methods.
Ans (D)- either an element or a compound. Elements and compounds are pure substances. They have uniform composition and cannot be separated by physical means to its simpler components (for compounds) or cannot be separated at all because it is already the simplest component (elements).
