A substance that cannot be separated physically is a pure substance.
A compound, such as water (H2O), cannot be physically separated into its component elements (hydrogen and oxygen) but can be chemically separated through a chemical reaction, such as electrolysis, which breaks the bonds between the elements.
A compound.
An element or compound that cannot be physically separated is an atom. Atoms are the smallest unit of matter that retains the properties of an element and cannot be further broken down by physical means. Compounds, on the other hand, can be separated into their individual elements through chemical reactions.

One way a mixture cannot be separated is if its components are chemically bonded together, forming a compound. This results in a homogeneous mixture where the individual components cannot be physically separated.
Elements
If a substance can be physically separated into its components, it is a mixture, not a pure substance. A pure substance consists of only one type of particle and cannot be separated into other substances by physical means.
A Lipid is insoluble. Aka a fatty acid.
A substance that cannot be separated physically is called a pure substance. This is because pure substances are made up of only one type of element or compound, and their composition is uniform throughout.
The substance is a compound, which forms chemical bonds that cannot be physically separated, but only by a chemical change.
